Description

Herbicidal mixtures based on 3-phenyluracils
The present invention relates to herbicidally active compositions comprising 3-phenyluracils and at least one further active compound selected from herbicidally active compounds and safeners.
In crop protection products, it is desirable in principle to increase the specificity and the reliability of the action of active compounds. In particular, it is desirable for the crop protection product to control the harmful plants effectively and, at the same time, to be tolerated by the useful plants in question.
Various publications have described 3-phenyluracils as being highly effective herbicides. However, their compatibility with dicotyledonous crop plants such as cotton, oilseed rape and some graminaceous plants such as barley, millet, corn, rice, wheat and sugar cane is not always satisfactory, i.e. in addition to the harmful plants, the crop plants are also damaged to an extent which is not acceptable. It is possible to spare the useful plants by lowering the application rates; however the extent of the control of harmful plants is naturally also reduced.
It is known that certain combinations of different herbicides with specific action result in an enhanced activity of a herbicide component by synergism. As a consequence, it is possible to reduce the application rates of herbicidally active compounds required for controlling the harmful plants.
Furthermore, it is known that in some cases better crop plant compatibility can be achieved by joint application of specifically acting herbicides with organic active compounds, some of which are themselves herbicidally active. In these cases, the active compounds act as antidote or antagonist, and, owing to the fact that they can reduce or even prevent damage to the crop plants, they are also referred to as safeners.
DE 195 06 202 describes herbicidal compositions comprising a herbicidally effective amount of a 3-phenyluracil and an antagonistically effective amount of a
3- ( 2-chloroρhenylmethyl)-1- ( 1-methyl-l-phenylethyl)urea and/or a
1-( 1-methyl-l-phenylethyl) -3-(4-tolyl)urea.
3-Phenyluracils of the formula I: in which the variables R1 - R7 are as defined below:
R1 is methyl or NH2;
R2 is Cχ-C-haloalkyl;
R3 is hydrogen or halogen;
R4 is halogen or cyano;
R5 is hydrogen, cyano, Cι-C6-alkyl, Cι-C6-alkoxy,
Cι-C-alkoxy-Cι-C -alkyl, C3-C7-cycloalkyl, C3-C6-alkenyl, C3-C6-alkynyl or benzyl which is unsubstituted or substituted by halogen or alkyl;
R6, R7 independently of one another are hydrogen, Ci-Cg-alkyl, Ci-Cβ-alkoxy, C3-C6-alkenyl, C3-C6-alkynyl, C3-C7-cycloalkyl, C3-C7-cycloalkenyl, phenyl or benzyl, where each of the 8 abovementioned substituents is unsubstituted or may be substituted by 1 to 6 halogen atoms and/or by one, two or three groups selected from: OH, NH2, CN, CONH2, Cι-C4-alkoxy, Cι-C4-haloalkoxy, Cι-C-alkylthio, Cι-C-haloalkylthio, C!-C-alkylsulfonyl, Cχ-C4-haloalkylsulfonyl, Cι-C4-alkylamino, di(Cι-C4-alkyl)amino, formyl, Cι-C4-alkylcarbonyl, Cι-C4-alkoxycarbonyl, Cι-C4-alkylaminocarbonyl, di(Cι-C4-alkyl)aminocarbonyl, C3-C7-cycloalkyl, phenyl and benzyl; or
R6, R7 together with the nitrogen atom form a 3-, 4-, 5-, 6- or 7-membered saturated or unsaturated nitrogen heterocycle which may be substituted by 1 to 6 methyl groups and which may contain 1 or 2 further heteroatoms selected from the group consisting of nitrogen, oxygen and sulfur as ring members, and their agriculturally acceptable salts are disclosed in the earlier patent application PCT/EP 01/04850.
It is an object of the present invention to increase the herbicidal activity of 3-phenyluracils of the formula I against undesirable harmful plants and to improve simultaneously their compatibility with useful plants.
We have found that this object is achieved, surprisingly, by compositions comprising at least one 3-phenyluracil of the formula I and/or at least one agriculturally acceptable salt of I and at least one further active compound, selected from
B) herbicides of classes bl) to bl5):
bl) lipid biosynthesis inhibitors; b2) acetolactate synthase inhibibitors (ALS inhibitors); b3 ) photosynthesis inhibitors; b4) protoporphyrinogen-IX oxidase inhibitors; b5) bleacher herbicides; b6) enolpyruvyl shikimate 3-phosphate synthase inhibitors
(EPSP inhibitors); b7 ) glutamine synthetase inhibitors ; b8) 7,8-dihydropteroate synthase inhibitors (DHP inhibitors); b9 ) mitose inhibitors; blO) inhibitors of the synthesis of long chain fatty acids
(VLCFA inhibitors); bll) cellulose biosynthesis inhibitors; bl2 ) decoupler herbicides; bl3) auxin herbicides; bl4) auxin transport inhibitors; bl5) other herbicides selected from the group consisting of benzoylprop, flamprop, flamprop-M, bromobutide, chlorflurenol, cinmethylin, methyldyuron, etobenzanid, fosamine, metam, pyributicarb, oxaziclomefone, dazomet, triaziflam and methyl bromide;
and
C) safeners selected from: benoxacor, cloquintocet, cyometrinil, dichlormid, dicyclonon, dietholate, fenchlorazole, fenclorim, flurazole, fluxofenim, furilazole, isoxadifen, mefenpyr, mephenate, naphthalic anhydride, 2,2,5-trimethyl-3-(dichloroacetyl)-l,3-oxazolidine (R-29148) , 4-(dichloroacetyl)-l-oxa-4-azaspiro[4.5]decane (AD-67; MON 4660) and oxabetrinil,
the agriculturally acceptable salts of the active compounds B and C and the agriculturally acceptable derivatives of the active compounds B and C, provided they have a carboxyl group.
The invention relates in particular to compositions in the form of herbicidally active crop protection compositions comprising a herbicidally effective amount of at least one mixture of A with B and/or C, as defined above, and at least one liquid and/or solid carrier and, if desired, one or more surfactants and, if desired, one or more further auxiliaries customary for crop protection compositions. The invention also relates to compositions in the form of a crop protection composition formulated as a 2-component composition comprising a first component which comprises the active compound A, a solid or liquid carrier and, if appropriate, one or more surfactants, and a second component which comprises at least one further active compound selected from the herbicides B and the safeners C, a solid or liquid carrier and, if appropriate, one or more surfactants, where both components may additionally comprise further auxiliaries customary for crop protection compositions .
The invention furthermore relates to a method for controlling undesirable vegetation, in particular in crops of cereals, corn, soybeans, rice, oilseed rape, cotton, potatoes, groundnuts or in perennial crops, and also in crops which, by genetic engineering or by breeding, are resistant to one or more herbicides or to attack by insects. The invention also relates to a method for the desiccation or defoliation of plants. In the latter methods it is immaterial whether the herbicidally active compounds of components A) and B) and/or C) are formulated and applied jointly or separately, and, in the case of separate application, in which order the application takes place.
The organic moieties mentioned in the definition of the substituents R2, R5, R6, R7 in formula I and R8 to R13 in formula II or as radicals on cycloalkyl, phenyl or heterocyclic rings are - like the term halogen - collective terms for individual enumerations of the individual group members. All hydrocarbon chains, i.e. all alkyl, haloalkyl, cycloalkyl, alkoxy, haloalkoxy, alkylamino, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, alkenyl and alkynyl groups and corresponding moieties in larger groups such as alkylcarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkoxycarbonyl, etc., can be straight-chain or branched, the prefix Cn-Cm denoting in each case the possible number of carbon atoms in the group. Halogenated substituents preferably carry one, two, three, four or five identical or different halogen atoms. The term halogen denotes in each case fluorine, chlorine, bromine or iodine.

The use forms depend entirely on the intended use.
The compositions according to the invention can be applied, for example, in the form of directly sprayable aqueous solutions, powders, suspensions, also highly-concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading or granules, by means of spraying, atomizing, dusting, broadcasting or watering. The use forms depend on the intended use; in any case, they should ensure the finest possible distribution of the active compounds.
Depending on the form in which the ready-to-use preparations are present in the compositions according to the invention, they comprise one or more liquid or solid carriers, if appropriate surfactants and if appropriate further auxiliaries which are customary for formulating crop protection products. The person skilled in the art is sufficiently familiar with the recipes for such formulations.
The ready-to-use preparations comprise the components A and B and/or C and auxiliaries which are customary for formulating crop protection products, which auxiliaries may also comprise a liquid carrier.
Suitable inert additives with carrier function are essentially: mineral oil fractions of medium to high boiling point, such as kerosene and diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, e.g. paraffins, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, alkylated benzenes and their derivatives, alcohols such as methanol, ethanol, propanol, butanol and cyσlohexanol, ketones such as cyclohexanone, strongly polar solvents, e.g. amines such as N-methylpyrrolidone, and wate .
Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the active compounds A) to C), as such or dissolved in an oil or solvent, can be homogenized in water by means of wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates consisting of active substance, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, and these concentrates are suitable for dilution with water.
Suitable surfactants are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, e.g. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, of alkyl- and alkylarylsulfonates, of alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols and of fatty alcohol glycol ethers, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene or of the naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alk lphenyl polyglycol ethers, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ether or polyoxypropylene alkyl ether, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignosulfite waste liquors or methylcellulose.
Powders, materials for spreading and dusts can be prepared by mixing or concomitant grinding of the active substances with a solid carrier.
Granules, e.g. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. Solid carriers are mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders, or other solid carriers.
The concentrations of the active compounds in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise from 0.001 to 98% by weight, preferably 0.01 to 95% by weight, of active ingredients. The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum). The compounds according to the invention can, for example, be formulated as follows:
I 20 parts by weight of the active compound or active compound mixture in question are dissolved in a mixture composed of 80 parts by weight of alkylated benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide to 1 mol of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active ingredient.
II 20 parts by weight of the active compound or active compound mixture in question are dissolved in a mixture composed of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 7 mol of ethylene oxide to 1 mol of isooctylphenol and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active ingredient.
III 20 parts by weight of the active compound or active compound mixture in question are dissolved in a mixture composed of 25 parts by weight of cyclohexanone, 65 parts by weight of a mineral oil fraction of boiling point 210 to 280°C and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active ingredient.
IV 20 parts by weight of the active compound or active compound mixture in question are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalenesulfonate, 17 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 60 parts by weight of pulverulent silica gel, and the mixture is ground in a hammer mill. Finely distributing the mixture in 20 000 parts by weight of water gives a spray mixture which comprises 0.1% by weight of the active ingredient. V 3 parts by weight of the active compound or active compound mixture in question are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of the active ingredient.
VI 20 parts by weight of the active compound or active compound mixture in question are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol-urea-formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.
VII 1 part by weight of the active compound or active compound mixture in question is dissolved in a mixture composed of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.
VIII 1 part by weight of the active compound or active compound mixture in question is dissolved in a mixture composed of 80 parts by weight of cyclohexanone and 20 parts by weight of Wettol® EM 31 (nonionic emulsifier based on ethoxylated castor oil). This gives a stable emulsion concentrate.
The components A and B and/or C can be formulated jointly or separately.
The components A and B and/or C can be applied jointly or separately, simultaneously or successively, before, during or after emergence of the plants .
If the active compounds A and B and/or C are less well tolerated by certain crop plants, it is possible to use application methods in which the herbicidal compositions are sprayed with the aid of sprayers in such a way that the leaves of the sensitive crop plants are as far as possible unaffected, whereas the active compounds reach the leaves of the undesirable plants growing underneath or the uncovered soil surface (post-directed, lay-by) .
The required application rate of pure active compound composition, i.e. of A and B and/or C without formulation auxiliary, depends on the composition of the plant stand, on the development stage of the plants, on the climatic conditions of the location where the composition is used and on the application method. In general, the application rate of A and B and/or C is from 0.001 to 3 kg/ha, preferably from 0.005 to 2 kg/ha and in particular from 0.01 to 1 kg/ha of active substance (a.s.).
The required application rates of phenyluracil are generally in the range from 0.1 g/ha to 1 kg/ha and preferably in the range from 1 g/ha to 500 g/ha or from 5 g/ha to 500 g/ha of a.s.
The compositions are applied to the plants mainly by foliar spraying. Application can be carried out by customary spraying techniques using, for example, water as carrier and spray liquor rates of from about 100 to 1 000 1/ha (for example from 300 to 400 1/ha) . Application of the herbicidal compositions by the low-volume and the ultra-low-volume method is possible, as is their application in the form of microgranules .
The compositions according to the present invention are suitable for controlling common harmful plants in useful plants, in particular in crops such as wheat, barley, oats, corn, soybean, sorghum, rice, oilseed rape, cotton, potatoes, dry beans, groundnuts or in perennial crops. In another embodiment of the invention, they are useful for controlling the whole vegetation, i. e. they act as a total weedkiller. Futhermore, in another emodiment of the present invention, the compositions are useful for controlling undesirable vegetation in forestry.
Moreover, it may be useful to apply the compositions according to the invention jointly as a mixture with other crop protection products, for example with pesticides or agents for controlling phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.
The compositions according to the invention can also be used in crop plants which are resistant to one or more herbicides owing to genetic engineering or breeding or which are resistant to attack by insects owing to genetic engineering or breeding. Suitable are for example crop plants which are resistant to herbicidal EPSP synthase inhibitors, such as, for example, glyphosate, to herbicidal glutamine synthase inhibitors, such as, for example, glufosinate, to herbicidal protoporphyrinogen-IX oxidase inhibitors, such as, for example, butafenacil, or to herbicidal ALS inhibitors, such as, for example, imazamethabenz, imazamox, imazapic, imazapyr, imazaquin, imazethapyr, or crop plants which, owing to introduction of the gene for Bt toxin by genetic modification, are resistant to attack by certain insects. Surprisingly, the compositions according to the invention which comprise at least one phenyluracil of the formula I and at least one herbicide B have better herbicidal activity against harmful plants than would have been expected by the herbicidal activity of the individual compounds. In other words, the joint application of phenyluracil I and herbicide B results in an enhanced activity against harmful plants in the sense of a synergy effect (synergism). For this reason, the mixtures can, based on the individual components, be used at lower application rates to achieve a herbicidal effect comparable to the individual components .
Surprisingly, the compositions according to the invention which, in addition to the phenyluracil I and, if appropriate, the herbicide B comprise an active compound from group C are better tolerated by useful plants than the respective phenyluracil I or the respective mixture of phenyluracil + herbicide B without active compound of group C.
The 3-phenyluracils of the formula I can be prepared by the preparation processes A to D described below, which are the subject of the earlier application PCT/EP 01/04850. With respect to the preparation of individual compounds, reference is made to the examples of PCT/EP 01/04850. Compounds which are not explicitly disclosed in this document can be prepared in an analogous manner.
In the schemes below, Q has the following meaning:
A) Reaction of a benzoic acid derivtive of the formula III in which R3, R4 and Q are as defined above with a sulfonamide IV, if appropriate in the presence of a coupling agent such as N,N-carbonyldiimidazole (CDI), or conversion of III into its acid chloride and subsequent reaction of the acid chloride of III with IV:
In general, the reaction with IV is preceded by activation of the carboxylic acid III. For activation, it is possible, for example, to convert III into its acid chloride by treatment of the acid III with S0C12, P0C13, PC15, C0C12 or (COCl)2. Alternatively, it is possible to prepare the imidazole by reaction of III with N,N-carbonyldiimidazole. These processes are generally known, for example from Houben Weyl, Methoden der Organischen Chemie [Methods of Organic Chemistry], Vol. E5 (1985), Part 1, p. 587 ff. and Vol. E5 (1985), part II, p. 934 ff.
As an alternative to the activation of III via its imidazolides or acid chlorides, it is also possible to use other customary methods of activating carboxylic acids for activating III.
In a typical embodiment, for example, N,N'-carbonyldiimidazole (CDI) is added to a solution of the carboxylic acid III in an inert solvent such as tetrahydrofuran. The resulting mixture is heated, preferably at reflux temperature, until complete conversion has been achieved, and is then cooled. The unsubstituted or substituted sulfonamide IV is added to this mixture, followed, if appropriate, by a nitrogen base, for example a tertiary amine or an amidine base such as diazabicycloundecane (DBU), and the mixture is stirred until the reaction has gone to completion. Conventional work-up and isolation in a customary manner gives the target compound I.
The benzoic acid derivatives III - and their corresponding esters, which can be hydrolyzed in a customary manner to give the free acids III - are known from the prior art or can be prepared in an analogous manner.
Processes for hydrolyzing the esters of III to the corresponding acids are likewise known from the prior art or can be carried out by standard methods for hydrolyzing esters (see also: Kocienski, "Protecting Groups", Thieme Verlag
1994; Greene, Wuts, Protecting groups in organic synthesis, Wiley 1999; Houben-Weyl, Methoden der organischen Chemie [Methods of organic chemistry], Vol. E5, Part I (1985), p. 223 ff.).
The acids III, such as 2-chloro-5-[3,6-dihydro-3-methyl- 2 , 6-dioxo-4- (trifluoromethyl)-1 (2H) -pyrimidinyl] -4-fluoro- benzoic acid (CAS No. 120890-57-5), and their esters are described, for example, in EP-A 195346, WO 89/02891, WO 98/08151 and the literature cited therein, or they can be prepared in the manner described therein.
Reaction of an aniline compound of the formula V with an oxazinone compound VI, giving a 3-phenyluracil of the formula VII which is then alkylated with an alkyl halide :
(R5 = H ; R2 = CF3 )
The oxazinone compounds VI are known, for example, from WO 99/14216. Here, R1 is preferably methyl.
The reaction of the aniline compound V with the oxazinone VI is usually carried out in a carboxylic acid, for example acetic acid, at temperatures in the range from 0 to 100°C, for example at room temperature, where the components are usually employed in equimolar amounts, or one of the components is employed in excess.
The alkylation of the aniline compound VII at the free uracil nitrogen is achieved in a manner known per se for uracils by reacting VII with an alkylating agent, preferably a methylating agent, for example a methyl halide, preferably methyl iodide, or dimethyl sulfate. The reaction is preferably carried out in the presence of a base, for example an alkali metal hydroxide or alkaline earth metal hydroxide, an alkali metal bicarbonate or, in particular, in the presence of an alkali metal carbonate. The alkylating agent is preferably employed in excess, based on VII. Suitable solvents are, in principle, all inert organic solvents, for example Cι-C4-alcohols, haloalkyl compounds such as dichloromethane, ethers such as tetrahydrofuran or dioxane and, preferably, polar aprotic solvents such as dimethylformamide or dimethyl sulfoxide.
The aniline compounds of the formula V can be prepared by customary methods, for example by converting the benzoic acid compound VIII analogously to the procedure described under A into the corresponding N-sulfonylcarboxamide IX, which is initially nitrated and then reduced to give the aniline V:
Suitable nitrating agents are, for example, nitric acid in various concentrations, including concentrated and fuming nitric acid, and also mixtures of nitric acid and sulfuric acid, acyl nitrates and alkyl nitrates. The nitration can be carried out in the absence of a solvent in an excess of the nitrating agent, or in an inert solvent or diluent, for example in water, in a mineral acid, in organic acids or in anhydrides thereof, such as acetic acid and acetic anhydride, in halogenated hydrocarbons such as methylene chloride, or in mixtures of the abovementioned solvents .
The N-sulfonylbenzamide IX and the nitrating agent can be employed, for example, in equimolar amounts. In terms of the yield of IX, it may be advantageous to employ the nitrating agent in an up to 10-fold molar excess, based on VIII. If the reaction is carried out in the absence of a solvent using the nitrating agent as diluent, the nitrating agent is frequently employed in an even greater excess.
The nitration is usually carried out at temperatures in the range from (-100 )°C to 200°C, preferably in the range from (-30) to 50°C.
The resulting nitro compound X is then reduced by customary methods to give the aniline compound V.
The reduction of X to V can be carried out in a customary manner. Usually, the reduction of X is carried out using a transition metal such as iron, zinc or tin under acidic reaction conditions, or by treating X with a complex hydride such as lithium aluminum hydride or sodium borohydride.
The reduction of X can be carried out in the absence of a solvent or in a solvent or diluent. Examples of suitable solvents are water, alcohols such as methanol, ethanol and isopropanol, and also ethers, for example diethyl ether, methyl tert-butyl ether, dioxane, tetrahydrofuran and ethylene glycol dimethyl ether, where the solvent is chosen in a manner known per se according to the reducing agent used.
If a metal serves as reducing agent, the reduction is preferably carried out in an inorganic acid, in particular in dilute or concentrated hydrochloric acid, or in a liquid organic acid, such as acetic acid or propionic acid. However, it is possible to mix the acid with one of the abovementioned solvents or diluents. The reduction of X with complex hydrides is usually carried out in an organic solvent, preferably in an ether or an alcohol. Nitro compound X and the reducing agent are frequently employed in approximately equimolar amounts; with respect to optimizing the reaction, it may also be advantageous to employ a relatively large excess of reducing agent, for example an up to 10-fold excess, based on the stoichiometric amount.
The amount of acid is of minor importance. To achieve complete conversion of the starting material, it is recommended to employ at least equimolar amounts of acid.
Frequently, the acid is also employed in excess, based on the nitro compound X.
The reduction is usually carried out at temperatures in the range from (-30) to 200°C, preferably in the range from 0 to 80°C.
For work-up, the reaction mixture is usually poured into water, and the aniline compound V is isolated by filtration or extraction with a water-immiscible solvent, for example ethyl acetate, diethyl ether or methylene chloride. If desired, the aniline compound V can be purified in a customary manner, for example by crystallization.
The hydrogenation of the nitro group in X can also be effected by catalytic hydrogenation. Examples of suitable catalysts are Raney-nickel, palladium on activated carbon, palladium oxide, platinum and platinum oxide. The amount of catalyst is usually in the range from 0.05 to 50 mol%, based on the nitro compound X to be reduced.
The hydrogen partial pressure required for the hydrogenation is usually in the range from atmospheric pressure to 50 bar.
The catalytic hydrogenation is frequently carried out in an inert solvent, for example in acetic acid, acetic acid/water mixtures, ethyl acetate or toluene. Following the removal of the catalyst, the reaction mixture is worked up in a customary manner, giving the aniline compound V.
Further suitable methods can be found in the literature (see, for example, Houben-Weyl, Methoden der Organischen Chemie, Stickstoffverbindungen [Nitrogen compounds] I, Part 1 (1971), Vol. X/l, P- 463 ff.) . Further methods which can be used in a similar manner for preparing the phenyluracils I are described in Bδger, Wakabayashi: Peroxidizing herbicides, Springer Verlag 1999.
Analogously to the synthesis route described here under B, it is also possible to prepare the carboxylic acid III starting from the carboxylic acid VIII.
C) Replacement of a halogen radical by a uracil radical Q:
Rl
(XI)
Hal = Halogen, preferably bromine or iodine.
Here, the aniline V is initially converted into the corresponding diazonium salt which is then, in a Sandmeyer reaction in a manner known per se, converted into the halogen compound XI, for example by treatment with copper(I) halide or copper(II) halide or, in the case of the iodide XI (Hal = 1), also by treatment of the diazonium salt of V with iodine/potassium iodide. These methods are generally known to the person skilled in the art, for example from Houben-Weyl, Methoden der Org. Chemie, Vol. 5/4, 4th edition 1960, p. 438 ff.
The reaction of XI with a uracil compound QH, preferably in the presence of a copper(I) compound as catalyst, then affords the corresponding 3-phenyluracil I.
By this route, it is also possible to prepare phenyluracils I where Hal = iodine similarly to the methods described by T. Maruyama, K. Fujiwara and M. Fukuhara in J. Chem. Soc, Perkin Trans. 1995 (7), pp. 733-734, using Cu(l) compounds.
D) Reaction of the benzoic ester XII, for example the methyl ester, with an electrophilic aminating agent, giving 3-( l-aminouracil-3-yl)benzoic ester XIII, hydrolysis of XIII to give 3- ( l-aminouracil-3-yl)benzoic acid XIV (where Ri = NH2) and conversion of XIV by the method described under A into the compound I where R1 = NH2 : (XII
Examples of electrophilic aminating agents are 2,4-dinitro- phenylhydroxylamine and O-mesitylenesulfonylhydroxylamine . Suitable reaction conditions for the electrophilic amination are given in DE-A 19 652 431, the disclosure of which on the electrophilic amination is expressly incorporated herein by way of reference.
The esters XII can be prepared from the corresponding 3-aminobenzoic acids or 3-aminobenzoic esters using the methods described under B. The hydrolysis of XIII to acid XIV is carried out by customary methods, for example in the presence of catalytic amounts of a mineral acid such as hydrochloric acid or sulfuric acid, or in the presence of an organic sulfonic acid, preferably in an aqueous or aqueous-alcoholic solvent. Alternatively, the "hydrolysis" can also be carried out under nonaqueous reaction conditions, for example by successive cleavage with a halogen transfer reagent such as boron tribromide or trimethylsilyl iodide and subsequent aqueous work-up.
In the preparation, the 3-phenyluracils I to be used according to the invention can be obtained as isomer mixtures which can be separated into the pure isomers using conventional methods, for example crystallization, chromatography and the like.
For further details about the preparation of the 3-phenyluracils I, reference is made to PCT EP/01/04850, in particular to the preparation examples.
Use Examples The effect of the herbicidal mixtures according to the invention of components A and B and, if appropriate, C on the growth of undesirable plants compared to the herbicidally active compounds alone was demonstrated by the following greenhouse experiments (Examples 1 to 11):
For the post-emergence treatment, the test plants were first grown to a height of 3 to 20 cm, depending on the plant habit, and only then treated. Here, the herbicidal compositions were suspended or emulsified in water as distribution medium and sprayed using finely distributing nozzles
The respective components A and B and/or C were formulated as 10% by weight strength emulsion concentrate and introduced to the spray liquor with the amount of solvent system used for applying the active compound. In the examples, the solvent used was water.
The test period extended over 21 days. During this time, the plants were tended, and their response to the treatments with active compound was evaluated.
The evaluation for the damage caused by the chemical compositions was carried out using a scale from 0 to 100%, compared to the untreated control plants. Here, 0 means no damage and 100 means complete destruction of the plants.
In the examples below, the value E which is to be expected if the activity of the individual compounds, is just additive was calculated using the method of S. R. Colby (1967) "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, p. 22 ff.
E = X + Y - (X-Y/100)
where
X = effect in percent using active compound A at an application rate a;
Y = effect in percent using active compound B at an application rate b;
