The preparation of these compounds and their use as herbicidally active ingredients are described.
Description




The present invention relates to novel herbicidally active substituted pyrazole derivatives, to processes for their preparation, to compositions comprising these compounds, and to their use for controlling weeds, in particular in crops of useful plants, for example cereals, maize, rice, cotton, soya, oilseed rape, sorghum, sugar cane, sugar beet, sunflowers, vegetables and fodder plants, or for inhibiting the growth of plants.




Herbicidally active pyrozole compounds have been disclosed and are described, for example, in JP-A-03 093 774, JP-A-02 300 173, JP-A-03 072 460, EP-A-0 361 114 and WO 96/01254.




There have now been found novel substituted pyrazole derivatives which have herbicidal and growth-inhibiting properties.




The present invention thus relates to compounds of the formula I

This condensation reaction and all subsequent reaction steps up to the nitrilo- and thioamidopyrazole derivatives of the formula I (Ia


1


, Ib

, Id and Ie) in accordance with reaction diagram 1 can be carried out in analogy to the procedure described in, for example, WO 96/01254 (page 20 et seq.).




According to this procedure, the diketo esters of the formula XIa are cyclized with a compound of the formula XIII, for example N-alkylhydrazine, at elevated temperature (reflux), preferably in glacial acetic acid, toluene or an alcohol as the solvent, to give the compounds of the formula V. If desired, an acid, for example sulfuric acid or p-toluenesulfonic acid may be employed as catalyst.




The subsequent conversion of the ester derivatives of the formula V into the corresponding amides of the formula II (Ila or llb) in accordance with reaction diagram 1 can be effected for example either directly by heating the ester derivatives in aqueous ammonia or, alternatively, via hydrolysis of the ester derivatives of the formula V to give the corresponding carboxylic acid derivatives of the formula Vi or Vj (R

or Ib

The choice of the suitable preparation method and the corresponding reaction conditions depends on the properties (reactivities) of the substituents in the intermediates in question.




The preparation processes of the pyrazole rings are illustrated in greater detail in reaction diagrams 2, 3 and 4 which follow.



























The pyrazole rings of the formulae Vc (reaction diagram 2, method a)) and XIXc (reaction diagram 3, method a)) are prepared by reacting the compounds of the formulae XIa, XId and XIe with hydrazine or hydrazine hydrate at elevated temperature.




To prepare the compound of the formula Vc, it is preferred to use glacial acetic acid or an alcohol as the solvent under mild reflux conditions, and for the preparation of the compound of the formula XIXc it is preferred to use toluene at elevated temperature. If desired, an acid, for example sulfuric acid or p-toluenesulfonic acid, may be employed as catalyst.




The pyrazole ring of the formula VIc, which is unsubstituted on the nitrogen atom (reaction diagram 4, method a), is preferably prepared from the compounds of the formula IXb in alcoholic solution with hydrazine hydrate at elevated temperature.




To prepare the pyrazole rings which are substituted on the nitrogen atom (reaction diagrams 2, 3 and 4, method b)) the procedure is as defined in analogy to method a), the reagent employed being the compound of the formula XIII, for example N-alkylhydrazine, preferably N-methylhydrazine.




The processes in accordance with method b) lead to isomer mixtures Va and Vb, XIXa and XIXb or VIa and VIb, the ratio of the two isomers depending, on the one hand, on the reaction conditions and, on the other hand, on the relevant intermediates of the formulae XIa, XId, XIe or XIb.




The mixtures of the isomeric pyrazole esters of the formulae Va and Vb can be readily separated into the pure isomers by means of silica gel chromatography and/or recrystallization. In general, the same also applies to the isomer mixtures of the formulae XIXa and XIXb, and VIa and VIb.




In certain cases, it is advantageous to prepare the N-alkyl-substituted pyrazole derivatives, in particular the N-methyl-substituted pyrazole derivatives, via N-alkylation of the corresponding unsubstituted pyrazoles of the formulae Vc, XIXc or VIc. This is illustrated in reaction diagram 5.

These solvents can also be employed in the form of a mixture.




This cyclization is successfully carried out at temperatures of from 0° C. to 100° C., preferably at from 5° C. to 80° C., over 0.5 to 24 hours.

The end products of the formula I can be isolated in the customary manner by concentrating or evaporating the solvent and purified by recrystallization or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons, by distillation or by means of column chromatography and a suitable eluent.




Those skilled in the art will furthermore know in which sequence certain reactions, for example in reaction diagrams 1, 12 and 14, are to be carried out expediently to avoid secondary reactions which may occur.




Unless a target-orientated synthesis is carried out for isolating pure isomers, the product may be obtained in the form of a mixture of two or more isomers. The isomers can be separated by methods known per se.




Suitable application methods for the use according to the invention of the compounds of the formula I or compositions comprising them are all those which are conventionally used in agriculture, for example pre-emergence application, post-emergence application and seed dressing, and also various methods and techniques, for example the controlled release of active ingredient. To this end, the dissolved active ingredient is applied to mineral carriers for granules or polymerized granules (urea/formaldehyde) and dried. If desired, a coating can additionally be applied (coated granules) which allows controlled release of the active ingredient over a specific period.




The compounds of the formula I can be employed in unaltered form, i.e. as obtained in synthesis, but they are preferably processed in the customary manner together with the auxiliaries conventionally used in the art of formulation, for example to give emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules or microcapsules. The application methods, such as spraying, atomizing, dusting, wetting, spreading or pouring and also the type of the compositions are chosen to suit the intended aims and the prevailing circumstances.




The formulations, i.e. the compositions, preparations or products comprising the active ingredient of the formula I or at least one active ingredient of the formula I and, as a rule, one or more solid or liquid formulation auxiliaries, are prepared in the known manner, for example by intimately mixing and/or grinding the active ingredients with the formulation auxiliaries, for example solvents or solid carriers. Furthermore, surface-active compounds (surfactants) may additionally be used when preparing the formulations.




Suitable solvents can be: aromatic hydrocarbons, preferably the fractions C


8


to C


12


, for example xylene mixtures or substituted naphthalenes, phthalic esters such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols, and their ethers and esters such as ethanol, ethylene glycol, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or N,N-dimethylformamide, and epoxidized or unepoxidized vegetable oils, such as epoxidized coconut oil or soya oil, or water.




Solid carriers which are used for example for dusts and dispersible powders are, as a rule, ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties of the formulation, it is also possible to add highly disperse silica or highly disperse absorptive polymers. Possible particulate, adsorptive carriers for granules are porous types, for example pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carrier materials are, for example, calcite or sand. In addition, a large number of pregranular materials of inorganic or organic nature, such as, in particular dolomite or comminuted plant residues, may be used.




Suitable surface-active compounds are, depending on the type of the active ingredient of the formula I to be formulated, non-ionic, cationic and/or anionic surfactants and surfactant mixtures which have good emulsifying, dispersing and wetting properties.




Suitable anionic surfactants can be not only so-called water-soluble soaps, but also water-soluble synthetic surface-active compounds.




Soaps which may be mentioned are the alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts of higher fatty acids (C


10


-C


22


), for example the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained, for example, from coconut or tallow oil. Mention must also be made of the fatty acid methyltaurinates.




However, so-called synthetic surfactants are used more frequently, in particular fatty alcohol sulfonates, fatty alcohol sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.




As a rule, the fatty alcohol sulfonates or fatty alcohol sulfates are present in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and have an alkyl radical of 8 to 22 C atoms, alkyl also including the alkyl moiety of acyl radicals, for example the sodium or calcium salt of lignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This section also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfo groups and one fatty acid radical of 8-22 C atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid of dibutylnaphthalene-sulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensate.




Other possible substances are suitable phosphates, for example salts of the phosphoric ester of a p-nonylphenol, (4-14)ethyleneoxide adduct, or phospholipids.




Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols.




Other suitable non-ionic surfactants are the water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The abovementioned compounds normally contain 1 to 5 ethylene glycol units per polypropylene glycol unit.




Examples which may be mentioned of non-ionic surfactants are nonylphenylpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol.




Also suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.




The cationic surfactants are, in particular, quaternary ammonium salts which contain, as N-substituents, at least one alkyl radical of 8 to 22 C atoms and as further substituents lower halogenated or unhalogenated alkyl, benzyl or lower hydroxyalkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.




The surfactants conventionally used in the art of formulation, which may also be used in the compositions according to the invention, are described, inter alia, in “Mc Cutcheon's Detergents and Emulsifiers Annual” MC Publishing Corp., Ridgewood N.J., 1981, Stache, H., “Tensid-Taschenbuch” [Surfactant Guide], Carl Hanser Verlag, Munich/Vienna, 1981, and M. and J. Ash, “Encyclopedia of Surfactants”, Vol I-III, Chemical Publishing Co., New York, 1980-81.




The herbicidal formulations comprise, as a rule, 0.1 to 99% by weight, in particular 0.1 to 95% by weight, of herbicide, 1 to 99.9% by weight, in particular 5 to 99.8% by weight, of a solid or liquid formulation auxiliary and 0 to 25% by weight, in particular 0.1 to 25% by weight, of a surfactant.




While concentrated compositions are more preferred as commercially available goods, the end user uses, as a rule, dilute compositions.




The compositions can also comprise other additives such as stabilizers, for example epoxidized or unepoxidized vegetable oils (epoxidized coconut oil, rapeseed oil or soya oil), antifoams for example silicone oil, preservatives, viscosity regulators, binders, tackifiers and fertilizers or other active ingredients.




Preferred formulations are composed in particular as follows:




(%=per cent by weight)





















Emulsifiable concentrates:








Active ingredient:




1 to 90%, preferably 5 to 50%







Surfactant:




5 to 30%, preferably 10 to 20%

15 to 94%, preferably 70 to 85%

Granules:







Active ingredient:




0.1 to 30%, preferably 0.1 to 15%







Solid carrier:

As a rule, the active ingredients of the formula I can be applied successfully to the plant or its environment at rates of application of 0.001 to 4 kg/ha, in particular 0.005 to 2 kg/ha, either as a mixture composed of the isomers Ia and Ib or as pure isomers Ia or Ib. The dosage required for the desired action can be determined by experiments. It depends on the type of action, the developmental stage of the crop plant and of the weed and on the application (location, timing, method) and it can vary within wide ranges due to these parameters.




The compounds of the formula I and, as a rule, especially the isomers of the formula Ia are distinguished by herbicidal and growth-inhibiting properties which make them suitable for use in crops of useful plants, in particular in cereals, cotton, soya, sugar beet, sugar cane, plantations, oilseed rape, maize and rice, and for non-selective weed control (‘total vegetation mangement’, TVM).




Crops are also to be understood as including those which have been made tolerant to herbicides or classes of herbicides by conventional plant-breeding or genetic engineering methods. The weeds to be controlled can be not only monocotyledoneous, but also dicotyledoneous weeds, for example Stellaria, Nasturtium, Agrostis, Digitaria, Avena, Setaria, Sinapis, Lolium, Solanum, Phaseolus, Echinochloa, Scirpus, Monochoria, Sagittaria, Bromus, Alopecurus, Sorghum halepense, Rottboellia, Cyperus, Abutilon, Sida, Xanthium, Amaranthus, Chenopodium, Ipomoea, Chrysanthemum, Galium, Viola and Veronica.

, n-hexane/ethyl acetate/glacial acetic acid=20/20/1 (v/v/v), UV) of a worked-up sample shows that all of the starting material has reacted.




The reaction mixture is poured into a mixture of ice and 2-molar hydrochloric acid and extracted with diethyl ether. The ether phase is washed with water and saline, dried over sodium sulfate, filtered and concentrated in vacuo. This gives 18.0 9 of a yellow solid which is introduced into 80 ml of glacial acetic acid. Thereupon, 3.2 ml of hydrazine hydrate are added slowly, using a syringe (exothermic). The mixture is subsequently refluxed gently overnight with stirring. The reaction mixture is evaporated to dryness in vacuo, and the residue is diluted with carbon tetrachloride and reconcentrated. The residue obtained is applied to 40 g of silica gel from ethyl acetate. After the silica gel had been applied to a flash chromatography column, it is eluted with a mixture of n-hexane/ethyl acetate/glacial acetic acid=100/50/1 (v/v/v).

) are placed into a 100 ml pressurized container and stirred for 16 hours at a temperature of 100° C. and a carbon monoxide pressure of 10 megapascal (Mpa). The solvent is subsequently evaporated and the crude product which remains is purified over a silica gel column (eluent: ethyl acetate/hexane 1/5). This gives 3.1 g (69.3% of theory) of the desired product.




EXAMPLE H14




3-(4-chloro-2-fluoro-5-carboxyphenyl)-4-methyl-5-cyano-1-methyl-[1H]-pyrazole
















3.1 g of 3-(4-chloro-2-fluoro-5-carbethoxyphenyl)-4-methyl-5-cyano-1-methyl-[1H]-pyrazole (Example H13) are dissolved in 22 ml of dioxane, and 10 ml of 2N aqueous sodium hydroxide solution are added dropwise at 22° C. The mixture is stirred until the reaction is complete, the solvent is evaporated, the resulting residue is dissolved in water and the solution is brought to pH 1using hydrochloric acid. The precipitate formed is filtered off and dried. This gives the desired product in a yield of 2.63 g (89.8% of theory).




EXAMPLE H15




3-(4-chloro-2-fluorophenyl)-4-methyl-5-cyano-1-methyl-[1H]-pyrazole (isomer A) and 3-(4-chloro-2-fluorophenyl)-4-cyano-1,5-dimethyl-[1H]-pyrazole (isomer B)
















16.3 g of 4-chloro-2-fluorophenylmethylhydrazonoyl bromide.hydrobromide are added to 275 ml of toluene and the mixture is stirred. 8.92 g of 2-bromo-2-butenonitrile are added to this stirred suspension, followed by the dropwise addition of 8.5 ml of triethylamine (exothermic). Stirring of the suspension is continued for 2 hours at 60° C. The mixture is cooled and then filtered, the solids are washed with toluene and the toluene phase is extracted with 1N aqueous hydrochloric acid, then washed with water and saline and dried over sodium sulfate. The solvent is evaporated and the resulting crude product is purified over a silica gel column (eluent: ethyl acetate/hexane 1/4). The products obtained are the desired isomer A in a yield of 7.68 g (65.4% of theory) and isomer B in a yield of 0.91 g (7.7% of theory).




EXAMPLE H16




3-(4-chloro-2-fluoro-5-(carboxylic acid-1-ethoxycarbonyl-1-methylethylester)phenyl)-4-methyl-5-cyano-1-methyl-[1H]-pyrazole
















2 drops of N,N-dimethylformamide (DMF) and then, dropwise, 1.01 g of oxalyl chloride are added to a stirred solution of 1.17 g of 3-(4-chloro-2-fluoro-5-carboxyphenyl)-4-methyl-5-cyano-1-methyl-[1H]-pyrazole (Example H14) in 30 ml of dry dichloromethane. This mixture is stirred for 1hour at 22° C. and subsequently refluxed for 10 minutes. The solvent and excess oxalyl chloride are evaporated and the resulting residue is dissolved in 30 ml of dry dichloromethane. A solution of 0.605 g of ethyl 2-hydroxyisobutyrate in 8 ml of pyridine is added dropwise to this solution, and this mixture is stirred overnight at 22° C. The solvent is subsequently evaporated, the resulting residue is dissolved in ethyl acetate, and this solution is washed first with water and then with saline and dried over sodium sulfate. The solvent is evaporated and the crude product is purified over a silica gel column (eluent: ethyl acetate/hexane 1/8). The desired product is obtained in a yield of 1.06 g (65.4% of theory).

Biological Examples




EXAMPLE B1




Herbicidal Action Before Emergence of the Plants (Pre-emergence Action)




Monocotyledoneous and dicotyledoneous test plants are grown in standard soil in plastic pots. Immediately after sowing, the test substances are sprayed on in the form of an aqueous suspension or emulsion, prepared from a 25% emulsion concentrate (Example F1, c)), which corresponds to a dosage of 500 g of a.i./ha (500 l of water/ha). The test plants are subsequently grown in the greenhouse under optimal conditions. After a test period of 3 weeks, the experiment is evaluated on a nine-step scale (1=complete damage, 9=no action). Score figures of 1 to 4 (in particular 1 to 3) denote a good to very good herbicidal action.




Test plants: Avena, Setaria, Solanum, Stellaria, Ipomoea.




The compounds according to the invention have good herbicidal activity.




Examples of the good herbicidal activity of the compounds of the formula I are given in Table B1.

The same results are obtained when the compounds of the formula I are formulated in accordance with Examples F2 to F8.




EXAMPLE B2




Post-emergence Herbicidal Action




In the greenhouse, monocotyledoneous and dicotyledoneous test plants are grown in standard soil in plastic pots and, in the 4- to 6-leaf stage, sprayed with an aqueous suspension or emulsion of the test substances of the formula I, prepared from a 25% emulsion concentrate (Example F1, c)), which corresponds to a dosage of 500 g of a.i./ha (500 l of water/ha). The test plants are subsequently grown on in the greenhouse under optimal conditions. After a test period of approximately 18 days, the experiment is evaluated on a nine-step scale (1=complete damage, 9=no action). Score figures of 1 to 4 (in particular 1 to 3) denote a good to very good herbicidal action.




Test plants: Setaria, Sinapis, Solanum, Stellaria, Ipomoea.




In this test too, the compounds of the formula I show a potent herbicidal activity.




Examples of the good herbicidal activity of the compounds of formula I are given in Table B2.
