Description

TITLE HERBICIDAL PYRIDAZINONE DERIVATIVES
FIELD OF THE INVENTION
This invention relates to certain pyridazinone derivatives, their JV-oxides, salts and compositions, and methods of their use for controlling undesirable vegetation.
BACKGROUND OF THE INVENTION
The control of undesired vegetation is extremely important in achieving high crop efficiency. Achievement of selective control of the growth of weeds especially in such useful crops as rice, soybean, sugar beet, maize, potato, wheat, barley, tomato and plantation crops, among others, is very desirable. Unchecked weed growth in such useful crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of undesired vegetation in noncrop areas is also important. Many products are commercially available for these purposes, but the need continues for new compounds that are more effective, less costly, less toxic, environmentally safer or have different sites of action.
SUMMARY OF THE INVENTION
This invention is directed to compounds of Formula 1 (including all geometric and stereoisomers), //-oxides, and salts thereof, agricultural compositions containing them and their use as herbicides:

"Haloalkylaminoalkyl" denotes a halogen group substituted with an alkylaminoalkyl group. "Haloalkylaminoalkyl" includes a halogen group attached to any alkyl groups as well as nitrogen. Examples of "haloalkylaminoalkyl" include CH3NHCH2CHCl-,
(CH3)CHCICH(CH3)NHCH2- and CH3NClCH(CH3)-. The term "halodialkylamino" denotes at least one halogen group substituted on any alkyl moiety of the dialkylamino group. Examples of "halodialkylamino" include CF3(CH3)N-, (CF3)2N- and CH2Cl(CH3)N-. "Cycloalkylamino" means the amino nitrogen atom is attached to a cycloalkyl radical and a hydrogen atom and includes groups such as cyclopropylamino, cyclobutylamino, cyclopentylamino and cyclohexylamino.
"Alkylcarbonyl" denotes a straight-chain or branched alkyl moieties bonded to a C(=0) moiety. Examples of "alkylcarbonyl" include CH3C(=O)-, CH3CH2CH2C(=O)- and (CH3)2CHC(=O)-. Examples of "alkoxycarbonyl" include CH3OC(=O)-, CH3CH2OC(=O)-, CH3CH2CH2OC(=O)-, (CH3)2CHOC(=O)- and the different butoxy- or pentoxycarbonyl isomers. The term "cycloalkylalkoxycarbonyl" denotes a cycloalkylalkyl moiety bonded to an oxygen atom of an oxycarbonyl moiety. Examples of "cycloalkylalkoxycarbonyl" include cyclopropyl-CH2OC(=O)-, cyclopropyl-CH(CH3)OC(=O)- and cyclopentyl- CH2OC(O)-.
The total number of carbon atoms in a substituent group is indicated by the "Ci-Cj" prefix where i and j are numbers from 1 to 14. For example, C1-C4 alkylsulfonyl designates methylsulfonyl through butylsulfonyl; C2 alkoxyalkyl designates CH3OCH2-; C3 alkoxyalkyl designates, for example, CH3CH(OCH3)-, CH3OCH2CH2- or CH3CH2OCH2-; and C4 alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH3CH2CH2OCH2- and CH3CH2OCH2CH2-.
The term "optionally substituted" means unsubstituted or substituted. Therefore an optionally substituted group (i.e. radical) is unsubstituted or has at least 1 non-hydrogen substituent. When an optionally substituted group is defined without specifying the optional substituents, the group is unsubstituted or has at least one non-hydrogen substituent that does not extinguish the biological activity possessed by the unsubstituted analog. When a list of possible substituents is specified, the optional substituents are independently selected from the list. Unless a particular limit is recited, a group can be substituted with as many optional substituents as can be accommodated by replacing a hydrogen atom with a non-hydrogen substituent on any available carbon or nitrogen atom in the group. Furthermore, each substitution is independent of the other. When the term "optionally substituted" is accompanied by a limit such as for the groups listed for J, the number of optional substituents cannot exceed the limit even if further positions for substitution are available. Therefore, for example, the phrase "optionally substituted with up to 5 substituents" means no substituent may be present, 1 substituent may be present, or up to 5 substituents may be present if accommodated by the number of positions available for substitution.
When the subscript indicates a range, e.g. (R)i-j, then the number of substituents may be selected from the integers between i and j inclusive. When a group contains a substituent which can be hydrogen, for example R1, R2, R3, R9, R10, R11, R12 or R13, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted. When a linking group is shown to be optionally present, for example (CR11R^)n wherein n may be 0, then the linking group may be a direct bond (i.e. when n is 0). When one or more positions on a group are said to be "not substituted" or "unsubstituted", then hydrogen atoms are attached to take up any free valency.
"Aromatic" indicates that each of the ring atoms is essentially in the same plane and has a /?-orbital perpendicular to the ring plane, and that (4n + T) π electrons, where n is a positive integer, are associated with the ring to comply with Hϋckel's rule. When a fully unsaturated carbocyclic ring satisfies Hϋckel's rule, then said ring is also called an "aromatic ring". When a fully unsaturated heterocyclic ring satisfies Hϋckel's rule, then said ring is also called a "heteroaromatic ring". Unless otherwise indicated, heterocyclic rings can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.
When J, G, or GA is a 5- or 6-membered nitrogen-containing heteroaromatic ring, it can be attached to the remainder of Formula 1 through any available carbon or nitrogen ring atom, unless otherwise described. As noted above, each J and GA can be (among others) independently a phenyl optionally substituted with one or more substituents selected from a group of substituents as defined in the Summary of Invention. An example of phenyl optionally substituted with one to five substituents is the ring illustrated as U-I in Exhibit 1, wherein Rv is Ru as defined in the Summary of the Invention for J and GA and r is an integer from 0 to 5.
As noted above, J and GA can be (among others) a 5- or 6-membered heteroaromatic ring, substituted or optionally substituted with one or more substituents selected from a group of substituents as defined in the Summary of the Invention. Examples of a 5- or 6- membered heteroaromatic ring, substituted or optionally substituted with one or more substituents include the rings U-2 through U-61 illustrated in Exhibit 1 wherein Rv is any substituent as defined in the Summary of the Invention for J and GA (i.e. Ru) and r is an integer from 0 to 4, limited by the number of available positions on each U group. In U-I through U-61, the radical (Rv)r correspond to (Ru)p in the Summary of the Invention and all Embodiments, Examples, Tables and Schemes. The subscript "r" represents the number of Rv (corresponding to "p" representing the number of Ru) substituents that can be present on U-I through U-61. As U-29, U-30, U-36, U-37, U-38, U-39, U-40, U-41, U-42 and U-43 have only one available position, for these U groups r is limited to the integers 0 or 1 , and r being 0 means that the U group is unsubstituted and a hydrogen is present at the position indicated by (Rv)r.

U-61 Although Rv (i.e Ru) groups are shown in the structures U-I through U-61, it is noted that they do not need to be present since they are optional substituents. The nitrogen atoms that require substitution to fill their valence are substituted with H or Rv (i.e Ru). Note that when the attachment point between (Rv)r (i.e (Ru)p) and the U group is illustrated as floating, (Rv)r (i.e (Ru)p) can be attached to any available carbon atom or nitrogen atom of the U group. Note that when the attachment point on the U group is illustrated as floating, the U group can be attached to the remainder of Formula 1 through any available carbon or nitrogen of the U group by replacement of a hydrogen atom. Note that some U groups can only be substituted with less than 4 Rv groups (e.g., U-2 through U-5, U-7 through U-48, and U-52 through U-61).
A wide variety of synthetic methods are known in the art to enable preparation of aromatic and nonaromatic heterocyclic rings and ring systems; for extensive reviews see the eight volume set of Comprehensive Heterocyclic Chemistry, A. R. Katritzky and C. W. Rees editors-in-chief, Pergamon Press, Oxford, 1984 and the twelve volume set of Comprehensive Heterocyclic Chemistry II, A. R. Katritzky, C. W. Rees and E. F. V. Scriven editors-in-chief, Pergamon Press, Oxford, 1996.
Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers or as an optically active form.
One skilled in the art will appreciate that not all nitrogen-containing heterocycles can form JV-oxides since the nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen containing heterocycles which can form TV-oxides. One skilled in the art will also recognize that tertiary amines can form JV-oxides. Synthetic methods for the preparation of //-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for the preparation of //-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J. Boulton and A. McKillop, Eds., Pergamon Press; M. R. Grimmett and B. R. T. Keene in Advances in Heterocyclic Chemistry, vol. 43, pp 149-161, A. R. Katritzky, Ed., Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemistry, vol. 9, pp 285-291, A. R. Katritzky and A. J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk in Advances in Heterocyclic Chemistry, vol. 22, pp 390-392, A. R. Katritzky and A. J. Boulton, Eds., Academic Press.
One skilled in the art recognizes that because in the environment and under physiological conditions salts of chemical compounds are in equilibrium with their corresponding nonsalt forms, salts share the biological utility of the nonsalt forms. Thus a wide variety of salts of the compounds of Formula 1 are useful for control of undesired vegetation (i.e. are agriculturally suitable). The salts of the compounds of Formula 1 include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. When a compound of Formula 1 contains an acidic moiety such as a carboxylic acid or enol (e.g., when R3 is H), salts also include those formed with organic or inorganic bases such as pyridine, triethylamine or ammonia, or amides, hydrides, hydroxides or carbonates of sodium, potassium, lithium, calcium, magnesium or barium. Accordingly, the present invention comprises compounds selected from Formula 1, JV-oxides and agriculturally suitable salts thereof.
One skilled in the art appreciates compounds of Formula 1, JV-oxides and salts thereof typically exist in more than one form, and Formula 1, JV-oxides and salts thereof thus include all crystalline and non-crystalline forms of the compounds they represent. Non-crystalline forms include embodiments which are solids such as waxes and gums as well as embodiments which are liquids such as solutions and melts. Crystalline forms include embodiments which represent essentially a single crystal type and embodiments which represent a mixture of polymorphs (i.e. different crystalline types). The term "polymorph" refers to a particular crystalline form of a chemical compound that can crystallize in different crystalline forms, these forms having different arrangements and/or conformations of the molecules in the crystal lattice. Although polymorphs can have the same chemical composition, they can also differ in composition due the presence or absence of co- crystallized water or other molecules, which can be weakly or strongly bound in the lattice. Polymorphs can differ in such chemical, physical and biological properties as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspensibility, dissolution rate and biological availability. One skilled in the art will appreciate that a polymorph of a compound of Formula 1 or //-oxides or salts thereof can exhibit beneficial effects (e.g., suitability for preparation of useful formulations, improved biological performance) relative to another polymorph or a mixture of polymorphs of the same compound of Formula 1 or JV-oxides or salts thereof. Preparation and isolation of a particular polymorph of a compound of Formula 1 or //-oxides or salts thereof can be achieved by methods known to those skilled in the art including, for example, crystallization using selected solvents and temperatures.

Scheme 4 shows the synthesis of compounds of Formula Ia by the dealkylation of compounds of Formula 3a (Formula 3 wherein Y is OAlkyl). Many dealkylation reagents which dealkylate ethers (such as compounds of Formula 3a), including aluminum trichloride, hydrogen bromide, iodotrimethylsilane and boron tribromide, are known in the art. Boron tribromide is preferred for the dealkylation. The alkoxy compound of Formula 3a is treated with boron tribromide in a solvent such as a chlorinated hydrocarbon (e.g., dichloromethane and chloroform). The reaction is typically carried out at 0 to 30 0C, but can also be carried out at more elevated temperatures such as between about 50 and 120 0C. Other conditions and reagents for dealkylation are described by Larock, "Comprehensive Organic Transformations", VCH Publishing, New York, 1989, pp 501-504.

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula 1 may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula 1. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than those implied by the particular sequence presented to prepare the compounds of Formula 1.
One skilled in the art will also recognize that compounds of Formula 1 and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Formulation/Utility
A compound Formula 1 of this invention will generally be used as a herbicidal active ingredient in a composition, i.e. formulation, with at least one additional component selected from the group consisting of surfactants, solid diluents and liquid diluents, which serves as a carrier. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature.
Useful formulations include both liquid and solid compositions. Liquid compositions include solutions (including emulsifϊable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like, which optionally can be thickened into gels. The general types of aqueous liquid compositions are soluble concentrate, suspension concentrate, capsule suspension, concentrated emulsion, microemulsion and suspo-emulsion. The general types of nonaqueous liquid compositions are emulsifϊable concentrate, microemulsifiable concentrate, dispersible concentrate and oil dispersion.
The general types of solid compositions are dusts, powders, granules, pellets, prills, pastilles, tablets, filled films (including seed coatings) and the like, which can be water-dispersible ("wettable") or water-soluble. Films and coatings formed from film- forming solutions or flowable suspensions are particularly useful for seed treatment. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the active ingredient. An emulsifϊable granule combines the advantages of both an emulsifϊable concentrate formulation and a dry granular formulation. High-strength compositions are primarily used as intermediates for further formulation.
Sprayable formulations are typically extended in a suitable medium before spraying. Such liquid and solid formulations are formulated to be readily diluted in the spray medium, usually water. Spray volumes can range from about from about one to several thousand liters per hectare, but more typically are in the range from about ten to several hundred liters per hectare. Sprayable formulations can be tank mixed with water or another suitable medium for foliar treatment by aerial or ground application, or for application to the growing medium of the plant. Liquid and dry formulations can be metered directly into drip irrigation systems or metered into the furrow during planting.
The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Liquid diluents also include glycerol esters of saturated and unsaturated fatty acids (typically C6-C22), such as plant seed and fruit oils (e.g., oils of olive, castor, linseed, sesame, corn (maize), peanut, sunflower, grapeseed, safflower, cottonseed, soybean, rapeseed, coconut and palm kernel), animal-sourced fats (e.g., beef tallow, pork tallow, lard, cod liver oil, fish oil), and mixtures thereof. Liquid diluents also include alkylated fatty acids (e.g., methylated, ethylated, butylated) wherein the fatty acids may be obtained by hydrolysis of glycerol esters from plant and animal sources, and can be purified by distillation. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950.
The solid and liquid compositions of the present invention often include one or more surfactants. When added to a liquid, surfactants (also known as "surface-active agents") generally modify, most often reduce, the surface tension of the liquid. Depending on the nature of the hydrophilic and lipophilic groups in a surfactant molecule, surfactants can be useful as wetting agents, dispersants, emulsifϊers or defoaming agents.
Surfactants can be classified as nonionic, anionic or cationic. Nonionic surfactants useful for the present compositions include, but are not limited to: alcohol alkoxylates such as alcohol alkoxylates based on natural and synthetic alcohols (which may be branched or linear) and prepared from the alcohols and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof; amine ethoxylates, alkanolamides and ethoxylated alkanolamides; alkoxylated triglycerides such as ethoxylated soybean, castor and rapeseed oils; alkylphenol alkoxylates such as octylphenol ethoxylates, nonylphenol ethoxylates, dinonyl phenol ethoxylates and dodecyl phenol ethoxylates (prepared from the phenols and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof); block polymers prepared from ethylene oxide or propylene oxide and reverse block polymers where the terminal blocks are prepared from propylene oxide; ethoxylated fatty acids; ethoxylated fatty esters and oils; ethoxylated methyl esters; ethoxylated tristyrylphenol (including those prepared from ethylene oxide, propylene oxide, butylene oxide or mixtures thereof); fatty acid esters, glycerol esters, lanolin-based derivatives, polyethoxylate esters such as polyethoxylated sorbitan fatty acid esters, polyethoxylated sorbitol fatty acid esters and polyethoxylated glycerol fatty acid esters; other sorbitan derivatives such as sorbitan esters; polymeric surfactants such as random copolymers, block copolymers, alkyd peg (polyethylene glycol) resins, graft or comb polymers and star polymers; polyethylene glycols (pegs); polyethylene glycol fatty acid esters; silicone-based surfactants; and sugar-derivatives such as sucrose esters, alkyl polyglycosides and alkyl polysaccharides.
Useful anionic surfactants include, but are not limited to: alkylaryl sulfonic acids and their salts; carboxylated alcohol or alkylphenol ethoxylates; diphenyl sulfonate derivatives; lignin and lignin derivatives such as lignosulfonates; maleic or succinic acids or their anhydrides; olefin sulfonates; phosphate esters such as phosphate esters of alcohol alkoxylates, phosphate esters of alkylphenol alkoxylates and phosphate esters of styryl phenol ethoxylates; protein-based surfactants; sarcosine derivatives; styryl phenol ether sulfate; sulfates and sulfonates of oils and fatty acids; sulfates and sulfonates of ethoxylated alkylphenols; sulfates of alcohols; sulfates of ethoxylated alcohols; sulfonates of amines and amides such as 7V,iV-alkyltaurates; sulfonates of benzene, cumene, toluene, xylene, and dodecyl and tridecylbenzenes; sulfonates of condensed naphthalenes; sulfonates of naphthalene and alkyl naphthalene; sulfonates of fractionated petroleum; sulfosuccinamates; and sulfosuccinates and their derivatives such as dialkyl sulfosuccinate salts.
Useful cationic surfactants include, but are not limited to: amides and ethoxylated amides; amines such as JV-alkyl propanediamines, tripropylenetriamines and dipropylenetetramines, and ethoxylated amines, ethoxylated diamines and propoxylated amines (prepared from the amines and ethylene oxide, propylene oxide, butylene oxide or mixtures thereof); amine salts such as amine acetates and diamine salts; quaternary ammonium salts such as quaternary salts, ethoxylated quaternary salts and diquaternary salts; and amine oxides such as alkyldimethylamine oxides and bis-(2-hydroxyethyl)-alkylamine oxides.
Also useful for the present compositions are mixtures of nonionic and anionic surfactants or mixtures of nonionic and cationic surfactants. Nonionic, anionic and cationic surfactants and their recommended uses are disclosed in a variety of published references including McCutcheon 's Emulsifiers and Detergents, annual American and International Editions published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964; and A. S. Davidson and B. Milwidsky, Synthetic Detergents, Seventh Edition, John Wiley and Sons, New York, 1987.
Compositions of this invention may also contain formulation auxiliaries and additives, known to those skilled in the art as formulation aids (some of which may be considered to also function as solid diluents, liquid diluents or surfactants). Such formulation auxiliaries and additives may control: pH (buffers), foaming during processing (antifoams such polyorganosiloxanes), sedimentation of active ingredients (suspending agents), viscosity (thixotropic thickeners), in-container microbial growth (antimicrobials), product freezing (antifreezes), color (dyes/pigment dispersions), wash-off (film formers or stickers), evaporation (evaporation retardants), and other formulation attributes. Film formers include, for example, polyvinyl acetates, polyvinyl acetate copolymers, polyvinylpyrrolidone-vinyl acetate copolymer, polyvinyl alcohols, polyvinyl alcohol copolymers and waxes. Examples of formulation auxiliaries and additives include those listed in McCutcheon 's Volume 2: Functional Materials, annual International and North American editions published by McCutcheon's Division, The Manufacturing Confectioner Publishing Co.; and PCT Publication WO 03/024222.
The compound of Formula 1 and any other active ingredients are typically incorporated into the present compositions by dissolving the active ingredient in a solvent or by grinding in a liquid or dry diluent. Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. If the solvent of a liquid composition intended for use as an emulsifiable concentrate is water-immiscible, an emulsifier is typically added to emulsify the active-containing solvent upon dilution with water. Active ingredient slurries, with particle diameters of up to 2,000 μm can be wet milled using media mills to obtain particles with average diameters below 3 μm. Aqueous slurries can be made into finished suspension concentrates (see, for example, U.S. 3,060,084) or further processed by spray drying to form water-dispersible granules. Dry formulations usually require dry milling processes, which produce average particle diameters in the 2 to 10 μm range. Dusts and powders can be prepared by blending and usually grinding (such as with a hammer mill or fluid-energy mill). Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, December 4, 1967, pp 147-48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. 4,144,050, U.S. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. 5,180,587, U.S. 5,232,701 and U.S. 5,208,030. Films can be prepared as taught in GB 2,095,558 and U.S. 3,299,566.

Test results indicate that the compounds of the present invention are highly active preemergent and/or postemergent herbicides and/or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or postemergence weed control in areas where complete control of all vegetation is desired such as around fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, air fields, river banks, irrigation and other waterways, around billboards and highways and railroad structures. Many of the compounds of this invention, by virtue of selective metabolism in crops versus weeds, or by selective activity at the locus of physiological inhibition in crops and weeds, or by selective placement on or within the environment of a mixture of crops and weeds, are useful for the selective control of grass and broadleaf weeds within a crop/weed mixture. One skilled in the art will recognize that the preferred combination of these selectivity factors within a compound or group of compounds can readily be determined by performing routine biological and/or biochemical assays. Compounds of this invention may show tolerance to important agronomic crops including, but not limited to, alfalfa, barley, cotton, wheat, rape, sugar beets, corn (maize), sorghum, soybeans, rice, oats, peanuts, vegetables, tomato, potato, perennial plantation crops including coffee, cocoa, oil palm, rubber, sugarcane, citrus, grapes, fruit trees, nut trees, banana, plantain, pineapple, hops, tea and forests such as eucalyptus and conifers (e.g., loblolly pine), and turf species (e.g., Kentucky bluegrass, St. Augustine grass, Kentucky fescue and Bermuda grass). Compounds of the present invention are particularly useful for selective weed control in crops of corn, rice (both upland and paddy), soybeans and wheat. Compounds of this invention can be used in crops genetically transformed or bred to incorporate resistance to herbicides, express proteins toxic to invertebrate pests (such as Bacillus thuringiensis toxin), and/or express other useful traits. Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful to modify plant growth.
As the compounds of the invention have both preemergent and postemergent herbicidal activity, to control undesired vegetation by killing or injuring the vegetation or reducing its growth, the compounds can be usefully applied by a variety of methods involving contacting a herbicidally effective amount of a compound of the invention, or a composition comprising said compound and at least one of a surfactant, a solid diluent or a liquid diluent, to the foliage or other part of the undesired vegetation or to the environment of the undesired vegetation such as the soil or water in which the undesired vegetation is growing or which surrounds the seed or other propagule of the undesired vegetation.
A herbicidally effective amount of the compounds of this invention is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general, a herbicidally effective amount of compounds of this invention is about 0.0001 to 20 kg/ha with a preferred range of about 0.001 to 5 kg/ha and a more preferred range of about 0.004 to 3 kg/ha. One skilled in the art can easily determine the herbicidally effective amount necessary for the desired level of weed control.
Compounds of this invention can also be mixed with one or more other biologically active compounds or agents including herbicides, herbicide safeners, fungicides, insecticides, nematocides, bactericides, acaricides, growth regulators such as insect molting inhibitors and rooting stimulants, chemosterilants, semiochemicals, repellents, attractants, pheromones, feeding stimulants, plant nutrients, other biologically active compounds or entomopathogenic bacteria, virus or fungi to form a multi-component pesticide giving an even broader spectrum of agricultural protection. Mixtures of the compounds of the invention with other herbicides can broaden the spectrum of activity against additional weed species, and suppress the proliferation of any resistant biotypes. Thus the present invention also pertains to a composition comprising a herbicidally effective amount of a compound of Formula 1 and a biologically effective amount of at least one additional biologically active compound or agent and can further comprise at least one of a surfactant, a solid diluent or a liquid diluent. The other biologically active compounds or agents can be formulated in compositions comprising at least one of a surfactant, solid or liquid diluent. For mixtures of the present invention, one or more other biologically active compounds or agents can be formulated together with a compound of Formula 1, to form a premix, or one or more other biologically active compounds or agents can be formulated separately from the compound of Formula 1, and the formulations combined together before application (e.g., in a spray tank) or, alternatively, applied in succession.
A mixture of one or more of the following herbicides with a compound of this invention may be particularly useful for weed control: acetochlor, acifluorfen and its sodium salt, aclonifen, acrolein (2-propenal), alachlor, alloxydim, ametryn, amicarbazone, amidosulfuron, aminocyclopyrachlor and its esters (e.g., methyl, ethyl) and salts (e.g., sodium, potassium), aminopyralid, amitrole, ammonium sulfamate, anilofos, asulam, atrazine, azimsulfuron, beflubutamid, benazolin, benazolin-ethyl, bencarbazone, benfluralin, benfuresate, bensulfuron-methyl, bensulide, bentazone, benzobicyclon, benzofenap, bifenox, bilanafos, bispyribac and its sodium salt, bromacil, bromobutide, bromofenoxim, bromoxynil, bromoxynil octanoate, butachlor, butafenacil, butamifos, butralin, butroxydim,

In certain instances, combinations of a compound of this invention with other biologically active (particularly herbicidal) compounds or agents (i.e. active ingredients) can result in a greater-than-additive (i.e. synergistic) effect on weeds and/or a less-than-additive effect (i.e. safening) on crops or other desirable plants. Reducing the quantity of active ingredients released in the environment while ensuring effective pest control is always desirable. Ability to use greater amounts of active ingredients to provide more effective weed control without excessive crop injury is also desirable. When synergism of herbicidal active ingredients occurs on weeds at application rates giving agronomically satisfactory levels of weed control, such combinations can be advantageous for reducing crop production cost and decreasing environmental load. When safening of herbicidal active ingredients occurs on crops, such combinations can be advantageous for increasing crop protection by reducing weed competition.
Of note is a combination of a compound of Formula 1 with at least one other herbicidal active ingredient. Of particular note is such a combination where the other herbicidal active ingredient has a different site of action from the compound of Formula 1. In certain instances, a combination with at least one other herbicidal active ingredient having a similar spectrum of control but a different site of action will be particularly advantageous for resistance management. Thus, a composition of the present invention can further comprise a biologically effective amount of at least one additional herbicidal active ingredient having a similar spectrum of control but a different site of action. Herbicidally effective amounts of compounds of the invention as well as herbicidally effective amounts of other herbicides can be easily determined by one skilled in the art through simple experimentation.

Compounds of this invention can also be used in combination with herbicide safeners such as benoxacor, BCS (l-bromo-4-[(chloromethyl)sulfonyl]benzene), cloquintocet-mexyl, cyometrinil, cyprosulfamide, dichlormid, dicyclonon, dietholate, 2-(dichloromethyl)-2- methyl-l,3-dioxolane (MG 191), fenchlorazole-ethyl, fenclorim, flurazole, fluxofenim, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, mephenate, methoxyphenone ((4-methoxy-3- methylphenyl)(3-methylphenyl)methanone), naphthalic anhydride (1,8-naphthalic anhydride) and oxabetrinil to increase safety to certain crops. Antidotally effective amounts of the herbicide safeners can be applied at the same time as the compounds of this invention, or applied as seed treatments. Therefore an aspect of the present invention relates to a herbicidal mixture comprising a compound of this invention and an antidotally effective amount of a herbicide safener. Seed treatment is particularly useful for selective weed control, because it physically restricts antidoting to the crop plants. Therefore a particularly useful embodiment of the present invention is a method for selectively controlling the growth of undesired vegetation in a crop comprising contacting the locus of the crop with a herbicidally effective amount of a compound of this invention wherein seed from which the crop is grown is treated with an antidotally effective amount of safener. Antidotally effective amounts of safeners can be easily determined by one skilled in the art through simple experimentation.
Compounds of this invention can also be used in combination with plant growth regulators such as aviglycine, Λ/-(phenylmethyl)-lH-purin-6-amine, epocholeone, gibberellic acid, gibberellin A4 and Aγ, harpin protein, mepiquat chloride, prohexadione calcium, prohydrojasmon, sodium nitrophenolate and trinexapac-methyl, and plant growth modifying organisms such as Bacillus cereus strain BPOl.

For embodiments where one or more of these various mixing partners are used, the weight ratio of these various mixing partners (in total) to the compound of Formula 1 is typically between about 1 :3000 and about 3000:1. Of note are weight ratios between about 1 :300 and about 300:1 (for example ratios between about 1 :30 and about 30:1). One skilled in the art can easily determine through simple experimentation the biologically effective amounts of active ingredients necessary for the desired spectrum of biological activity. It will be evident that including these additional components may expand the spectrum of weeds controlled beyond the spectrum controlled by the compound of Formula 1 alone.
The following Tests demonstrate the control efficacy of the compounds of this invention against specific weeds. The weed control afforded by the compounds is not limited, however, to these species. See Index Table A for compound descriptions. The following abbreviations are used in the Index Tables which follow: t is tertiary, i is iso, c is cyclo, Me is methyl, CΗ3O or OMe is methoxy, Pr is propyl, z-Pr is isopropyl, c-Pr is cyclopropyl, t-Bu is tert-butyl SO2 means sulfonyl (S(O )j), and naphthyl means naphthalenyl, CF3 is trifluoromethyl, CF3O is trifluoromethoxy, THP means tetrahydropyranyl, Ph means phenyl, NO2 is nitro, Cl is chloro, F is fluoro and Br is bromo.

Cmpd. No. means Compound number. a H NMR data are in ppm downfield from tetramethylsilane. Couplings are designated by (s)-singlet, (m)-multiplet, (d)-doublet, (q)-quartet, (dd) doublet of doublets, (br)- broad and (t)-triplet. " Mass spectra are reported as the molecular weight of the highest isotopic abundance parent ion (M+l) formed by addition of H+ (molecular weight of 1) to the molecule, observed by mass spectrometry using atmospheric pressure chemical ionization (AP+). BIOLOGICAL EXAMPLES OF THE INVENTION
TEST A
Seeds of species selected from barnyardgrass (Echinochloa crus-galli), large crabgrass {Digitaria sanguinalis), giant foxtail (Setaria faberi), blackgrass (Alopecurus myosuroides), canarygrass (Phalaris minor), morningglory (Ipomoea coccinea), pigweed (Amaranthus retroflexus), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), and corn (Zea mays) were planted into a blend of loam soil and sand and treated preemergence with a directed soil spray using test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant. At the same time these species were also treated with postemergence applications of test chemicals formulated in the same manner.
Plants ranged in height from 2 to 10 cm and were in the one- to two-leaf stage for the postemergence treatment. Treated plants and untreated controls were maintained in a greenhouse for approximately 10 days, after which time all treated plants were compared to untreated controls and visually evaluated for injury. Plant response ratings, summarized in Table A, are based on a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash (-) response means no test results.

TEST B
Seeds of plant species selected from blackgrass (Alopecurus myosuroides), downy bromegrass (Bromus tectorum), green foxtail (Setaria viridis), Italian ryegrass (Lolium multiflorum), wheat (Triticum aestivum), wild oat (Avena fatua), catchweed bedstraw (Galium aparine), bermudagrass (Cynodon dactyloή), Surinam grass (Brachiaria decumbens), cocklebur (Xanthium strumarium), corn (Zea mays), large crabgrass (Digitaria sanguinalis), woolly cupgrass {Eήochloa villosά), giant foxtail (Setaria faberii), goosegrass (Eleusine indica), johnsongrass {Sorghum halepense), kochia (Kochia scoparia), lambsquarters (Chenopodium album), morningglory (Ipomoea coccinea), eastern black (E.B.) nightshade (Solarium ptycanthum), yellow nutsedge (Cyperus esculentus), pigweed (Amaranthus retroflexus), common ragweed (Ambrosia elatior), Russian thistle (Salsola iberica), soybean (Glycine max), common (oilseed) sunflower (Helianthus annuus), and velvetleaf (Abutilon theophrasti) were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant.
At the same time, plants selected from these crop and weed species and also winter barley (Hordeum vulgare), canarygrass (Phalaris minor), chickweed (Stellaria media) and windgrass (Apera spica-venti) were treated with postemergence applications of some of the test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments.
Plant species in the flooded paddy test consisted of rice (Oryza sativa), umbrella sedge (Cyperus difformis), ducksalad (Heteranthera limosa) and barnyardgrass (Echinochloa crus- galli) grown to the 2-leaf stage for testing. At time of treatment, test pots were flooded to 3 cm above the soil surface, treated by application of test compounds directly to the paddy water, and then maintained at that water depth for the duration of the test. Treated plants and controls were maintained in a greenhouse for 13 to 15 days, after which time all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table B, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

TESTC
Seeds of plant species selected from annual bluegrass (Poa annua), blackgrass (Alopecurus myosuroides), canola (Brassica rapa), downy bromegrass (Bromus tectorum), green foxtail (Setaria viridis), Italian ryegrass (Lolium multiflorum), canarygrass (Phalaris minor), pigweed (Amaranthus retroflexus), spring barley (Hordeum vulgare), spring wheat (Triticum aestivum), wild mustard {Sinapis arvensis), wild oat {Avena fatua), windgrass (Apera spica-venti), winter barley {Hordeum vulgare), and winter wheat {Triticum aestivum) were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant. At the same time, plants selected from these crop and weed species were treated with postemergence applications of some of the test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4- leaf stage) for postemergence treatments.
Treated plants and controls were maintained in a controlled growth environment for 15 to 25 days after which time all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table C, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

TEST D
Three plastic pots (ca. 16-cm diameter) for each application rate were partially filled with sterilized Tama silt loam soil comprising a 35:50:15 ratio of sand, silt and clay and 2.6% organic matter. Separate plantings for each of the three pots were as follows. Seeds from the U.S. of ducksalad (Heteranthera limosά), umbrella sedge (Cyperus difformis) and purple redstem (Ammannia coccinea), were planted into one 16-cm pot for each rate. Seeds from the U.S. of rice flatsedge {Cyperus iriά), bearded (Brdd.) sprangletop (Leptochloa fascicularis), one stand of 9 or 10 water-seeded rice seedlings (Oryza sativa cv. 'Japonica - M202'), and one stand of 6 transplanted rice seedlings {Oryza sativa cv. 'Japonica - M202') were planted into one 16-cm pot for each rate. Seeds from the U.S. of barnyardgrass {Echinochloa crus-galli), late watergrass {Echinochloa oryzicola), early watergrass {Echinochloa oryzoides) and junglerice {Echinochloa colona) were planted into one 16-cm pot for each rate. Plantings were sequential so that crop and weed species were at the 2.0 to 2.5-leaf stage at time of treatment.
Potted plants were grown in a greenhouse with day/night temperature settings of 30/27 0C, and supplemental balanced lighting was provided to maintain a 16-hour photoperiod. Test pots were maintained in the greenhouse until test completion.
At time of treatment, test pots were flooded to 3 cm above the soil surface, treated by application of test compounds directly to the paddy water, and then maintained at that water depth for the duration of the test. Effects of treatments on rice and weeds were visually evaluated by comparison to untreated controls after 21 days. Plant response ratings, summarized in Table D, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

TESTE
Seeds of plant species selected from bermudagrass (Cynodon dactyloή), Surinam grass (Brachiaria decumbens), large crabgrass (Digitaria sanguinalis), green foxtail (Setaria viridis), goosegrass (Eleusine indica), johnsongrass {Sorghum halepense), kochia (Kochia scoparia), pitted morningglory (Ipomoea lacunosa), purple nutsedge (Cyperus rotundus), common ragweed {Ambrosia elatior), black mustard (Brassica nigra), guineagrass (Panicum maximum), dallisgrass (Paspalum dilatatum), barnyardgrass (Echinochloa crus-galli), southern (S.) sandbur (Cenchrus echinatus), common sowthistle (Sonchus oleraceous), prickly sida (Sida spinosa), Italian ryegrass (Lolium multiflorum), common purslane (Portulaca oleracea), broadleaf signalgrass (Brachiaria platyphylla), common groundsel (Senecio vulgaris), common chickweed (Stellaria media), Virginia (V.) dayflower (Commelina virginica), tropical (T.) spiderwort (Commelina benghalensis), annual bluegrass (Poa annua), naked crabgrass (Digitaria nuda), itchgrass (Rottboellia cochinchinensis), quackgrass (Elytrigia repens), Canada horseweed (Conyza canadensis), field bindweed (Convolvulus arvensis), spanishneedles (Bidens bipinnata), common mallow (Malva sylvestris) and Russian thistle (Salsola kali) were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant. At the same time, plants selected from these weed species were treated with postemergence applications of some of the test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments.
Treated plants and controls were maintained in a greenhouse for 14 to 21 days, after which time all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table E, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

TESTF
This test evaluated the effect of mixtures of Compound 3, Compound 11, or Compound 12 with the commercial crop safener cloquintocet-mexyl on three plant species. Seeds of test plants consisting of winter wheat (TRZAW, Tήticum aestivum), winter barley (HORVX, Hordeum vulgare), and wild oat (AVEFA, Avena fatua) (a weed) were planted into a blend of loam soil and sand and treated preemergence with a directed soil spray using test chemicals formulated in a non-phytotoxic solvent mixture that included a surfactant. At the same time, plants selected from these crop and weed species were treated with postemergence applications of the test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments.
Plants were grown in a greenhouse using supplemental lighting to maintain a photoperiod of about 16 hours; daytime and nighttime temperatures were about 24-30 0C and 19-21 0C, respectively. Balanced fertilizer was applied through the watering system. Treatments consisted of Compound 3, Compound 11, or Compound 12 and the above mentioned safener alone and in combination using a spray volume of 457 L/ha. Each treatment was replicated three times. Treated plants and controls were maintained in a greenhouse for 14 to 21 days, after which time all treated plants were compared to controls and visually evaluated. Plant response ratings were calculated as the means of the three replicates and are summarized in Tables Fl to F6, and are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. Because cloquintocet-mexyl alone caused no injury at the rates tested, the expected effect of a mixture of Compound 3 with cloquintocet- mexyl is the same as the observed effect of Compound 3 applied alone. The observed and expected additive effects are listed in Tables Fl to F6. Table Fl - Observed and Expected Results from Compound 3 Alone and in Combination with cloquintocet-mexyl*

Application rates are grams of active ingredient per hectare (g a.i./ha). "Obsd." is observed effect. "Exp; is expected effect.
As can be seen from the results listed in Table Fl, the observed results for TRZAW at three of the six combination treatments and for HORVX at five of the six combination treatments were less than expected, thereby indicating safening at these mixture application rates of Compound 3 and cloquintocet-mexyl.

TEST G
This test evaluated the effect of mixtures of Compound 26 with commercial crop safeners cloquintocet-mexyl, mefenpyr-diethyl, and fenchlorazole-ethyl on three plant species. Seeds of winter wheat (TRZAW, Triticum aestivum), winter barley (HORVX, Hordeum vulgare), and wild oat (AVEFA, Avena fatua) (a weed) were planted into a silt loam soil. Plants from these seeds were treated postemergence using test chemicals formulated in a non-phytotoxic solvent mixture that included a surfactant. Plants ranged in height from 6 to 10 cm (2- to 3 -leaf stage).
Plants were grown in a greenhouse using supplemental lighting to maintain a photoperiod of about 14 hours; daytime and nighttime temperatures were about 22-26 0C and 15-19 0C, respectively. Balanced fertilizer was applied through the watering system. Treatments consisted of Compound 26 and the above mentioned safeners alone and in combination using a spray volume of 281 L/ha. Each treatment was replicated four times. Treated plants and controls were maintained in a greenhouse for 15 days, after which time all treated plants were compared to controls and visually evaluated. Plant response ratings were calculated as the means of the four replicates based on a scale of 0 to 100 where 0 is no effect and 100 is complete control and are summarized in Tables Gl to G3. Because the safeners alone caused no injury at the rates tested, the expected effect of a mixture of Compound 26 with a safener is the same as the observed effect of Compound 26 alone. The observed and expected effects are listed in Tables Gl to G3.
The highest application rate of each safener was tested alone to confirm the absence of herbicidal activity on the test species when appled postemergence at 125 g ai/ha. Therefore, an extrapolated result of zero for each safener alone at 16, 31, or 62 g ai/ha was used to calculate the mixture response of Compound 26 and these safener application rates.
