[0006] It will be appreciated by those skilled in the art that the most preferred compounds are generally those which are comprised of combinations of the above preferred classes.
[0007] The invention includes herbicidal compositions comprising an herbicidally effective amount of a compound of Formula I and agriculturally acceptable derivatives of the carboxylic acid group in a mixture with an agriculturally acceptable adjuvant or carrier. The invention also includes a method of use of the compounds and compositions of the present invention to kill or control undesirable vegetation by application of an herbicidal amount of the compound to the vegetation or to the locus of the vegetation as well as to the soil prior to emergence of the vegetation.
[0008] The herbicidal compounds of the present invention are derivatives 1of 6-amino-5-(alkyl, alkenyl or alkynyl)-4-pyrimidinecarboxylic acids of the formula:
la wherein A represents N; R1 represents CrC2 alkyl, CrC2 haloalkyl, C2-C3 alkenyl or C2-C3 haloalkenyl; R2 represents cyclopropyl, CrC6 haloalkyl, C2-C6 alkenyl, C2-C6 haloalkenyl or wherein

The amino group can be further derivatized as an amide, a carbamate, a urea, a sulfonamide, a silylamine or a phos-phoramidate. Such derivatives are capable of breaking down into the amine. An unsubstituted amino group or one substituted with one or two alkyl substituents is preferred.
[0010] The carboxylic acids of Formula la are believed to be the compounds that actually kill or control undesirable vegetation and are typically preferred. Analogs of these compounds in which the acid group of the pyrimidine carboxylic acid; is derivatized to form a related substituent that can be transformed within plants or the environment to an acid group possess essentially the same herbicidal effect and are within the scope of the invention. Therefore, an "agriculturally acceptable derivative", when used to describe the carboxylic acid functionality at the 4-position of the pyrimidine ring is defined as any salt, ester, or amide which (a) does not substantially affect the herbicidal activity of the active ingredient, i.e., the 2-(substituted)-6-amino-5-(alkyl, alkenyl or alkynyl)-4-pyrimidinecarboxylic acid and (b) is or can be hydrolyzed, oxidized or metabolized in plants or soil to the 4-pyrimidinecarboxylic acid of Formula la that, depending upon the pH, is in the dissociated or the undissociated form.
[0011] Likewise, an "agriculturally acceptable derivative", when used to describe the amine functionality at the 6-position, is defined as any salt, silylamine, phosphorylamine, phosphinimine, phosphoramidate, sulfonamide, sulfilimine, sulfoximine, aminal, hemiaminal, amide, thioamide, carbamate, thiocarbamate, amidine, urea, imine, nitro, nitroso, azide, or any other nitrogen containing derivative well known in the art which (a) does not substantially affect the herbicidal activity of the active ingredient, i.e., the 2-(substituted)-6-amino-5-(alkyl, alkenyl or alkynyl)-4-pyrimidinecarboxylic acid and (b) is or can be hydrolyzed in plants or soil to a free amine. N-Oxides which are also capable of breaking into the parent pyrimidine are also covered by the scope of this invention.
[0012] Suitable salts include those derived from alkali or alkaline earth metals and those derived from ammonia and amines. Preferred cations include sodium, potassium, magnesium, and aminium cations of the formula:
wherein Rg, R9 and R10 each, independently represents hydrogen or C.|-C12 alkyl, C3-C12 alkenyl or C3-C12 alkynyl, each of which is optionally substituted by one or more hydroxy, C^-C4 alkoxy, CyC4 alkylthio or phenyl groups, provided that Rg, R9 and R10 are sterically compatible. Additionally, any two of R8, Rg and R10 together may represent an aliphatic difunctional moiety containing 1 to 12 carbon atoms and up to two oxygen or sulfur atoms. Salts of the compounds of Formula I can be prepared by treatment of compounds of Formula I with a metal hydroxide, such as sodium hydroxide, or an amine, such as ammonia, trimethylamine, diethanolamine, 2-methylthiopropylamine, bisallylamine, 2-butoxyethyl-amine, morpholine, cyclododecylamine, or benzylamine. Amine salts are often preferred forms of the compounds of Formula I because they are water-soluble and lend themselves to the preparation of desirable aqueous based herbicidal compositions.
[0013] Suitable esters include those derived from CpC12 alkyl, C3-C12 alkenyl or C3-C12 alkynyl alcohols, such as methanol, /so-propanol, butanol, 2-ethylhexanol, butoxyethanol, methoxypropanol, allyl alcohol, propargyl alcohol or cyclohexanol. Esters can be prepared by coupling of the 4-pyrimidine carboxylic acids with the alcohol using any number of suitable activating agents such as those used for peptide couplings such as dicyclohexylcarbodiimide (DCC) or carbonyl diimidazole (CDI), by reacting the corresponding acid chloride of a 4-pyrimidinecarboxylic acid of Formula I with an appropriate alcohol, by reacting the corresponding 4-pyrimidinecarboxylic acid of Formula I with an appropriate alcohol in the presence of an acid catalyst or by transesterification. Suitable amides include those derived from ammonia or from C.|-C12 alkyl, C3-C12 alkenyl or C3-C12 alkynyl mono- or disubstituted amines, such as but not limited to dimeth-ylamine, diethanolamine, 2-methylthiopropylamine, bisallylamine, 2-butoxyethylamine, cyclododecylamine, benzylamine or cyclic or aromatic amines with or without additional heteroatoms such as but not limited to aziridine, azetidine, pyrrolidine, pyrrole, imidazole, tetrazole or morpholine. Amides can be prepared by reacting the corresponding 4-pyri-midinecarboxylicacid :chloride, mixed anhydride, or carboxylic ester of Formula I with ammonia or an appropriate amine.

Scheme 5
[0027] It is recognized that some reagents and reaction conditions disclosed herein or in the chemical literature for preparing compounds of Formula I 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 protection groups will be apparent to one skilled in chemical synthesis.
[0028] One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as disclosed herein or in the chemical literature, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula I. One skilled in the art will also recognize that it may necessary to perform a combination of the steps disclosed herein or in the chemical literature in an order other than that implied by the particular sequence presented to prepare the compounds of Formula I.
[0029] Finally, one skilled in the art will also recognize that compounds of Formula I and the intermediates described herein or in the chemical literature can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.
[0030] The compounds of Formula I have been found to be useful as preemergence and post-emergence herbicides. They can be employed at non-selective (higher) rates of application to control a broad spectrum of the vegetation in an area or at lower rates of application for the selective control of undesirable vegetation. Areas of application include pasture and rangelands, roadsides and rights of way, power lines and any industrial areas, as well as turf and ornamental environments where control of undesirable vegetation is desirable. Another use is the control of unwanted vegetation in crops such as corn, rice and cereals. They can also be used to control undesirable vegetation in tree crops such as citrus, apple, rubber, oil palm, forestry and others. It is usually preferred to employ the compounds postemergence. It is further usually preferred to use the compounds to control a wide spectrum of woody plants, broad leaf and grass weeds, and sedges. Use of the compounds to control undesirable vegetation in established crops is especially indicated. While each of the 2-(substituted)-6-amino-5-(alkyl, alkenyl or alkynyl)-4-pyrimidinecarboxylate compounds encompassed by Formula I is within the scope of the invention, the degree of herbicidal activity, the crop selectivity, and the spectrum of weed control obtained varies depending upon the substituents present. An appropriate compound for any specific herbicidal utility can be identified by using the information presented herein and routine testing.
[0031] The term herbicide is used herein to mean an active ingredient that kills, controls or otherwise adversely modifies the growth of plants. An herbicidally effective or vegetation controlling amount is an amount of active ingredient which causes an adversely modifying effect and includes deviations from natural development, killing, regulation, desiccation, retardation, and the like. The terms plants and vegetation include germinant seeds, emerging seedlings and established vegetation.
[0032] Herbicidal activity is exhibited by the compounds of the present invention when they are applied directly to the plant or to the locus of the plant at any stage of growth or before planting or emergence. The effect observed depends upon the plant species to be controlled, the stage of growth of the plant, the application parameters of dilution and spray drop size, the particle size of solid components, the environmental conditions at the time of use, the specific compound employed, the specific adjuvants and carriers employed, the soil type, and the like, as well as the amount of chemical applied. These and other factors can be adjusted as is known in the art to promote non-selective or selective herbicidal action. Generally, it is preferred to apply the compounds of Formula I postemergence to relatively immature undesirable vegetation to achieve the maximum control of weeds.
[0033] Application rates of 1 to 1,000 g/Ha are generally employed in postemergence operations; for preemergence applications, rates of 10 to 2,000 g/Ha are generally employed. The higher rates designated generally give non-selective control of a broad variety of undesirable vegetation. The lower rates typically give selective control and can be employed in the locus of crops.
[0034] The herbicidal compounds of the present invention are often applied in conjunction with one or more other herbicides to control a wider variety of undesirable vegetation. When used in conjunction with other herbicides, the presently claimed compounds can be formulated with the other herbicide or herbicides, tank mixed with the other herbicide or herbicides or applied sequentially with the other herbicide or herbicides.

It is generally preferred to use the compounds of the invention in combination with herbicides that are selective for the crop being treated and which complement the spectrum of weeds controlled by these compounds at the application rate employed. It is further generally preferred to apply the compounds of the invention and other complementary herbicides at the same time, either as a combination formulation or as a tank mix.
[0035] The compounds of the present invention can generally be employed in combination with known herbicide safeners, such as benoxacor, benthiocarb, brassinolide, cloquintocet (mexyl), cyometrinil, daimuron, dichlormid, dicy-clonon, dimepiperate, disulfoton, fenchlorazole-ethyl, fenclorim, flurazole, fluxofenim, furilazole, isoxadifen-ethyl, mefen-pyr-diethyl, MG 191, MON 4660, naphthalic anhydride (NA), oxabetrinil, R29148 and N-phenyl-sulfonylbenzoic acid amides, to enhance their selectivity. They can additionally be employed to control undesirable vegetation in many crops that have been made tolerant to or resistant to them or to other herbicides by genetic manipulation or by mutation and selection. For example, corn, wheat, rice, soybean, sugarbeet, cotton, canola, and other crops that have been made tolerant or resistant to compounds that are acetolactate synthase inhibitors in sensitive plants can be treated. Many glyphosate and glufosinate tolerant crops can be treated as well, alone or in combination with these herbicides. Some crops (e.g. cotton) have been made tolerant to auxinic herbicides such as 2,4-dichlorophenoxyacetic acid. These herbicides may be used to treat such resistant crops or other auxin tolerant crops.
[0036] While it is possible to utilize the 2-(substituted)-6-amino-5-(alkyl, alkenyl or alkynyl)-4-pyrimidinecarboxylate compounds of Formula I directly as herbicides, it is preferable to use them in mixtures containing an herbicidally effective amount of the compound along with at least one agriculturally acceptable adjuvant or carrier. Suitable adjuvants or carriers should not be phytotoxic to valuable crops, particularly at the concentrations employed in applying the compositions for selective weed control in the presence of crops, and should not react chemically with the compounds of Formula I or other composition ingredients. Such mixtures can be designed for application directly to weeds or their locus or can be concentrates or formulations that are normally diluted with additional carriers and adjuvants before application. They can be solids, such as, for example, dusts, granules, water dispersible granules, orwettable powders, or liquids, such as, for example, emulsifiable concentrates, solutions, emulsions or suspensions.
[0037] Suitable agricultural adjuvants and carriers that are useful in preparing the herbicidal mixtures of the invention are well known to those skilled in the art.
[0038] Liquid carriers that can be employed include water, toluene, xylene, petroleum naphtha, crop oil, acetone, methyl ethyl ketone, cyclohexanone, trichloroethylene, perchloroethylene, ethyl acetate, amyl acetate, butyl acetate, propylene glycol monomethyl ether and diethylene glycol monomethyl ether, methanol, ethanol, isopropanol, amyl al cohol, ethylene glycol, propylene glycol, glycerine, A/-methyl-2-pyrrolidinone, A/.W-dimethyl alkylamides, dimethyl sulfoxide, liquid fertilizers and the like. Water is generally the carrier of choice for the dilution of concentrates.
[0039] Suitable solid carriers include talc, pyrophyllite clay, silica, attapulgus clay, kaolin clay, kieselguhr, chalk, dia-tomaceous earth, lime, calcium carbonate, bentonite clay, Fuller’s earth, cotton seed hulls, wheat flour, soybean flour, pumice, wood flour, walnut shell flour, lignin, and the like.
[0040] It is usually desirable to incorporate one or more surface-active agents into the compositions of the present invention. Such surface-active agents are advantageously employed in both solid and liquid compositions, especially those designed to be diluted with carrier before application. The surface-active agents can be anionic, cationic or nonionic in character and can be employed as emulsifying agents, wetting agents, suspending agents, or for other purposes. Typical surface-active agents include salts of alkyl sulfates, such asdiethanolammonium lauryl sulfate; alkylarylsulfonate salts, such as calciumdodecyl-benzenesulfonate; alkylphenol-alkylene oxide addition products, such as nonylphenol-C18 ethoxylate; alcohol-alkylene oxide addition products, such as tridecyl alcohol-C16 ethoxylate; soaps, such as sodium stearate; alkylnaphthalene-sulfonate salts, such as sodium dibutylnaphthalenesulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di(2-ethylhexyl) sulfosuccinate; sorbitol esters, such as sorbitol oleate; quaternary amines, such as lauryl trimethylammonium chloride; polyethylene glycol esters of fatty acids, such as polyethylene glycol stearate; block copolymers of ethylene oxide and propylene oxide; and salts of mono and dialkyl phosphate esters.
[0041] Other adjuvants commonly used in agricultural compositions include compatibilizing agents, antifoam agents, sequestering agents, neutralizing agents and buffers, corrosion inhibitors, dyes, odorants, spreading agents, penetration aids, sticking agents, dispersing agents, thickening agents, freezing point depressants, antimicrobial agents, and the like. The compositions may also contain other compatible components, for example, other herbicides, plant growth régulants, fungicides, insecticides, and the like and can be formulated with liquid fertilizers or solid, particulate fertilizer carriers such as ammonium nitrate, urea and the like.
[0042] The concentration of the active ingredients in the herbicidal compositions of this invention is generally from 0.001 to 98 percent by weight. Concentrations from 0.01 to 90 percent by weight are often employed. In compositions designed to be employed as concentrates, the active ingredient is generally present in a concentration from 5 to 98 weight percent, preferably 10 to 90 weight percent. Such compositions are typically diluted with an inert carrier, such as water, before application. The diluted compositions usually applied to weeds or the locus of weeds generally contain 0. 0001.to 1 weight percent active ingredient and preferably contain 0.001 to 0.05 weight percent.
[0043] The present compositions can be applied to weeds or their locus by the use of conventional ground or aerial dusters, sprayers, and granule applicators, diffusion in standing water, by addition to irrigation water, and by other conventional means known to those skilled in the art.
