In addition, DE-A-33 32 633 describes pyrazole-3-carboxamides which are substituted in the 5-position of the heterocyclic ring by nitro, trifluoromethyl, halogen or C.sub.1 -C.sub.4 -alkoxy, as pharmaceuticals.
However, a herbicidal action of substances of this type was not found.
It is an object of the present invention to provide novel herbicidally active substances.
We have found that this object is achieved by the pyrazole-3-carboxamides I defined at the outset.
We have also found that the pyrazole-3-carboxamides I and the pyrazole-3-carboxamides Ia are suitable for controlling undesired plant growth.
The pyrazole-3-carboxamides I according to the invention can be prepared by various processes, for example by the following:
1. A process for the preparation of a compound I in which R.sup.5 is CO.sub.2 R' and R' is C.sub.1 -C.sub.4 -alkyl ##STR6##
These pyrazole-3-carboxamides I are obtained by reacting a dialkyl pyrazole-3,4-dicarboxylate of the formula II in a conventional manner in an inert organic solvent with an amine of the formula III ##STR7##
R' in the formulae II and I is C.sub.1 -C.sub.4 -alkyl, such as methyl, ethyl, propyl, 1-methylethyl, butyl, 1-methylpropyl, 2-methylpropyl or 1,1-dimethylethyl, preferably methyl, ethyl or 1-methylethyl.
The reaction is generally carried out at from 0.degree. to 100.degree. C., preferably from 50.degree. to 80.degree. C., in an inert organic solvent.
Suitable solvents are halogenated hydrocarbons, such as chlorobenzene and 1,2-dichlorobenzene, ethers, such as methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxane; alcohols, such as methanol, ethanol, propanol and ethylene glycol, dipolar aprotic solvents, such as acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone and 1,3-dimethylimidazolin-2-one, or aromatic compounds, such as benzene, toluene and xylene. The process is particularly preferably carried out in the alcohol corresponding to the ester component.
The concentration of the starting materials in the solvent is generally from 0.1 to 5.0 mol/l, preferably from 0.2 to 2.0 mol/l.
The molar ratio between II and III is generally from 1:2.5 to 1:1, preferably from 1:1.5 to 1:1.
A particularly preferred process involves the use of a diester II and an amine III in the ratio 1:1 in the absence of solvents at from 50.degree. to 80.degree. C.
The pyrazoledicarboxylates II required as starting materials for this process are known from the literature or can be prepared by methods known from the literature (cf. J. Heterocyclic Chem. 25, (1988) 1293; J. Am. Chem. Soc. 73, (1951) 3684; J. Org. Chem. 31, (1966) 2491; J. Heterocyclic Chem. 22, (1985) 565; Chem. Ber. 101, (1968) 536; Chem. Ber. 101, (1968) 1059; Chem. Ber. 107, (1974) 3036).
The amines V required are either commercially available or can be prepared by conventional processes.
A particularly preferred process for the preparation of the pyrazole-3-carboxamides of the formula I comprises converting a pyrazole-3,4-dicarboxylate of the formula IIa into a monocarboxylic acid IIb using an aqueous base. The compound IIb can be converted into the desired amide via the acyl chloride intermediate using an amine of the formula III. ##STR8## R' is C.sub.1 -C.sub.4 -alkyl, such as methyl, ethyl, propyl, iso-propyl, n-butyl or sec-butyl, preferably ethyl or iso-propyl.
The reaction is carried out by reacting a pyrazoledicarboxylate IIa in an inert solvent with an aqueous base at from -30.degree. C. to 120.degree. C., preferably from -10.degree. C. to 40.degree. C. The pyrazolemonocarboxylic acid of the formula IIa is then liberated at from -30.degree. C. to 100.degree. C., preferably from -10.degree. C. to 10.degree. C., by adding a mineral acid.
Suitable solvents are alcohols, such as methanol, ethanol, propanol or ethylene glycol, preferably the alcohol which corresponds to the ester component in II. The concentration of the starting material II is generally from 0.1 to 0.5 mol/l, preferably from 0.2 to 2.0 mol/l.
The aqueous base employed is a 5 to 20% strength aqueous solution of an alkali metal hydroxide or alkaline earth metal hydroxide, such as LiOH, NaOH, KOH, Ca(OH).sub.2 or Ba(OH).sub.2, preferably NaOH or KOH.
The molar ratio between the diester IIa and hydroxide is from 1:0.95 to 1:1 for an alkali metal hydroxide and from 1:0.48 to 1:0.55 for an alkaline earth metal hydroxide.
The reaction is generally complete after 14 hours. The monocarboxylic acid IIb is then liberated by adding a strong mineral acid such as hydrochloric acid or sulfuric acid and isolated in a conventional manner, for example by suction filtration or extraction with an organic solvent.
For conversion into the acyl halide, the carboxylic acid IIb is reacted with a halogenating agent, preferably an inorganic acid halide, if desired in an inert solvent, with addition of a catalytic amount of N,N-dimethylformamide or 4-N,N-dimethylaminopyridine, at from 0.degree. C. to the boiling point of the solvent (mixture) or halogenating agent used.
Suitable inert solvents are halogenated hydrocarbons, such as tetrachloroethane, methylene chloride, chloroform, dichloroethane, chlorobenzene and 1,2-dichlorobenzene, or aromatic compounds, such as benzene, toluene or zylene, preferably benzene or toluene.
Expedient halogenating agents are inorganic acid halides, such as thionyl chloride, phosphorus trichloride or phosphorus pentachloride. The carboxylic acid III and halogenating agent are employed in a ratio of from 1:1 to 1:10, preferably from 1:1 to 1:5. The concentration of the catalyst (N,N-dimethylformamide or 4-N,N-dimethylaminopyridine) is from 1 to 20 mol-%, preferably from 1 to 5 mol-%, based on the carboxylic acid IIb employed.
If the reaction is carried out in a solvent, the concentration of the starting material IIb is from 0.1 to 5.0 mol/l, preferably from 0.2 to 2.0 mol/l.
The process is particularly preferably carried out using five equivalents of thionyl chloride in the presence of 2 mol-% of N,N-dimethylformamide at the reflux temperature of the reaction mixture.
The reaction is generally complete after 5 hours; the acyl chloride IV can be isolated in a conventional manner, for example by removing the excess inorganic acid halide and solvent by distillation and subsequently distilling the acyl halide which remains, if necessary under reduced pressure.
The amide I is obtained in a conventional manner by reacting a pyrazole-3-carbonyl chloride of the formula IV with an amine V. An expedient procedure is to react a solution of the acyl halide in an inert solvent with an amine III, likewise in an inert solvent. The acyl chloride and the amine III are expediently employed in a ratio of from 1:2 to 1:5, but it is also possible to carry out the reaction in the presence of an acid acceptor, in which case the acyl chloride and the amine III are expediently employed in a ratio of from 1:1 to 1:1.5 and the acyl chloride and the acid acceptor in a ratio of from 1:1.5 to 1:5.
The solvent used for these reactions is preferably a halogenated hydrocarbon, such as tetrachloroethane, methylene chloride, chloroform, dichloroethane, chlorobenzene or 1,2-dichlorobenzene, or an ether, e.g. diethyl ether, methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane; a dipolar aprotic solvent, e.g. acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone or 1,3-dimethylimidazolin-2-one; an aromatic compound, e.g. benzene, toluene or xylene, or a ketone, such as acetone or methyl ethyl ketone. The concentration from 0.1 to 5.0 mol/l, preferably from 0.2 to 2.0 mol/l.
The reaction can be carried out at from -30.degree. C. to the reflux temperature of the solvent (mixture) used.
Preferred acid acceptors are aromatic nitrogen bases, such as pyridine, 4-dimethylaminopyridine and quinoline; tertiary aliphatic amines, such as triethylamine, N-ethyldiisopropylamine and N-methylmorpholine; bicyclic and tricyclic amines, such as diazabicyclooctane (DABCO) and diazabicycloundecane (DBU); and carbonates or bicarbonates of alkali metals or of alkaline earth metals, e.g. sodium carbonate, potassium carbonate, sodium bicarbonate and potassium bicarbonate. It may in some cases also be useful to use combinations of the abovementioned bases.
The process is particularly preferably carried out at from 0.degree. to 30.degree. C. in a halogenated hydrocarbon, such as tetrachloroethane, methylene chloride, chloroform or dichloroethane, in the presence of three equivalents of the amine III. The reaction is generally complete after 14 hours; the mixture can be worked up in a conventional manner, for example by hydrolysis using water and extraction of the amide VI with an organic solvent. The product of formula VI can be purified as usual by recrystallization or chromatography.

C., preferably from 10.degree. to 80.degree. C. The pyrazolecarboxylic acid of the formula I (R.sup.5 =CO.sub.2 H) is then liberated at from -30.degree. to 100.degree. C., preferably from -10.degree. to 10.degree. C., by adding a mineral acid.

3. A process for the preparation of a compound I in which R.sup.5 is COYR.sup.6 ##STR11##
This compound is obtained, for example, by converting a pyrazole-3-carboxamide I in which R.sup.5 is CO.sub.2 H in a conventional manner into an activated form of the carboxylic acid, and subsequently esterifying the latter using a compound IV. ##STR12##
This reaction is usually carried out at from -20.degree. to 60.degree. C., preferably from 0.degree. to 40.degree. C.

The concentration of the starting materials in the solvent is generally from 0.1 to 5.0mol/l, preferably from 0.2 to 2.0 mol/l.
In general, from 1 to 1.5 mol equivalents, preferably from 1 to 1.15 mol equivalents, of the compound IV are employed, based on the carboxylic acid I (R.sup.5 =CO.sub.2 H).
Suitable dehydrating agents are diimides, such as dicyclohexylcarbodiimide, or anhydrides, such as propanephosphonic anhydride. The reaction is also successful in the presence of 1-methyl-2-halopyridinium iodides as the dehydrating agent (cf. Chem. Lett., (1975) 1045; ibid., (1976), 13; ibid., (1976), 49.

Suitable salts of compounds of the formula Ia are agriculturally useful salts, for example alkali metal salts, such as potassium and sodium salts, alkaline earth metal salts, such as calcium, magnesium and barium salts, manganese, copper, zinc or iron salts, e.g., ammonium salts, tetraalkylammonium salts, benzyltrialkylammonium salts, trialkylsulfonium salts and trialkylsulfoxonium salts.
The herbicidal compounds I, or agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), dispersions, emulsions, oil dispersions, pastes, dusts broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.
For the preparation of solutions, emulsions, pastes and oil dispersions to be sprayed direct, mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, further coal-tar oils, and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons such as toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, methanol, ethanol, propanol, butanol, cyclohexanol, cyclohexanone, chlorobenzene, isophorone, etc., and strongly polar solvents such as N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, water, etc. are suitable.
Aqueous formulations may be prepared from emulsion concentrates, pastes, oil dispersions, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes and oil dispersions the ingredients as such or dissolved in an oil or solvent may be homogenized in water by means of wetting or dispersing agents, adherents or emulsifiers. Concentrates which are suitable for dilution with water may be prepared from active ingredient, wetting agent, adherent, emulsifying or dispersing agent and possibly solvent or oil.
Examples of surfactants are: alkali metal, alkaline earth methal and ammonium salts of aromatic sulfonic acids, e.g., ligninsulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl and alkylaryl sulfonates, and alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexadecanols, heptadecanols, and octadecanols, salts of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ethers, ethoxylated isooctylphenol, ethoxylated octylphenol and ethoxylated nonylphenol, alkylphenol polyglycol ethers, tributylphenyl polyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignin-sulfite waste liquors and methyl cellulose.
Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients with a solid carrier.

Examples of solid carriers are mineral earths such as silicic acids, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain meals, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.
The formulations contain from 0.1 to 95, and preferably 0.5 to 90, % by weight of active ingredient. The active ingredients are used in a purity of 90 to 100, and preferably 95 to 100, % (according to the NMR spectrum).
Compounds I according to the invention may be formulated as follows:
I. 90 parts by weight of compound no. 1.014 is mixed with 10 parts by weight of N-methyl-alpha-pyrrolidone. A mixture is obtained which is suitable for application in the form of very fine drops.
II. 20 parts by weight of compound no. 1.022 is dissolved in a mixture consisting of 80 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 moles of ethylene oxide and 1 mole of oleic acid-N-monoethanolamide, 5 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, and 5 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mol of castor oil. By pouring the solution into 100,000 parts by weight of water and uniformly distributing it therein, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient.

By pouring the solution into 100,000 parts by weight of water and finely distributing it therein, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient.
IV. 20 parts by weight of compound no. 1.040 is dissolved in a mixture consisting of 25 parts by weight of cyclohexnanone, 65 parts by weight of a mineral oil fraction having a boiling point between 210.degree. and 280.degree. C., and 10 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into 100,000 parts by weight of water and uniformly distributing it therein, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient.

VII. 30 parts by weight of compound no. 1.022 is intimately mixed with a mixture consisting of 92 parts by weight of powdered silica gel and 8 parts by weight of paraffin oil which has been sprayed onto the surface of this silica gel. A formulation of the active ingredient is obtained having good adherence.

A stably oily dispersion is obtained.
The active ingredients or the herbicidal agents containing them may be applied pre- or postemergence. If certain crop plants tolerate the active ingredients less well, application techniques may be used in which the herbicidal agents are sprayed from suitable equipment in such a manner that the leaves of sensitive crop plants are if possible not touched, and the agents reach the soil or the unwanted plants growing beneath the crop plants (post-directed, lay-by treatment).
When the active ingredients are used as herbicides, the application rates depend on the objective to be achieved, the time of the year, the plants to be combated with their growth stage, and are from 0.001 to 5, preferably 0.01 to 2, kg of active ingredient per hectare.
To increase the spectrum of action and to achieve synergistic effects, the compounds I may be mixed with each other, or mixed and applied together with numerous representatives of other herbicidal or growth-regulating active ingredient groups. Examples of suitable components are diazines, 4H-3,1-benzoxazine derivatives, benzothiadiazinones, 2,6-dinitroanilines, N-phenylcarbamates, thiolcarbamates, halocarboxylic acids, triazines, amides, ureas, diphenyl ethers, triazinone, uracils, benzofuran derivatives, cyclohexane-1,3-dione derivatives, quinolinecarboxylic acids, (hetero)-aryloxyphenoxypropionic acids and salts, esters, amides thereof, etc.
It may also be useful to apply the herbicidal compounds Ia, either alone or in combination with other herbicides, in admixture with other crop protection agents, e.g., agents for combating pests or phytophathogenic fungi or bacteria. The compounds may also be mixed with solutions of mineral salts used to remedy nutritional or trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.

USE EXAMPLES
The herbicidal action of the pyrazole-3-carboxamides of the formula Ia is demonstrated in greenhouse experiments:
The vessels employed were plastic flowerpots having a volume of 300 cm.sup.3 and filled with a sandy loam containing about 3.0% humus. The seeds of the test plants were sown separately, according to species.
For the preemergence treatment, the formulated active ingredients were applied to the surface of the soil immediately after the seeds had been sown. The compounds were emulsified or suspended in water as vehicle, and sprayed through finely distributing nozzles. After the agents had been applied, the vessels were lightly sprinkler-irrigated to induce germination and growth. Transparent plastic covers were then placed on the vessels until the plants had taken root. The cover ensured uniform germination of the plants, insofar as this was not impaired by the active ingredients.
For the postemergence treatment, the plants were grown, depending on growth form, to a height of 3 to 15 cm before being treated with the compounds, suspended or emulsified in water. The application rate for postemergence treatment was 1.0 kg/ha.
The pots were set up in the greenhouse, heat-loving species at 20.degree. to 35.degree. C, and species from moderate climates at 10.degree. to 25.degree. C. The experiments were run for from 2 to 4 weeks. During this period the plants were tended and their reactions to the various treatments assessed. The assessment scale was 0 to 100, 100 denoting nonemergence or complete destruction of at least the visible plant parts, and 0 denoting no damage or normal growth.
The plants used in the experiments were Chenopodium album, Sinapis alba and Solanum nigrum.
Active ingredient nos. 1.014 and 1.022, applied postemergence at a rate of 1.0 kg/ha, provided excellent control of unwanted broadleaved plants.
