Oxazole- and thiazolecarboxylic acids and derivatives thereof are known (DE-A 2,254,944, Bull. Soc. Chim. Fr., 1969, 2152 and DE-A 2,221,647). Possible uses of these substances as herbicides have not been described.
It is an object of the present invention to find and synthesize novel herbicidal compounds.
We have found that this object is achieved by the oxazole- and thiazolecarboxamides Ia and Ib defined in the first paragraph.
We have also found processes for preparing them and herbicides which contain oxazole- and thiazolecarboxamides Ia' and Ib' in which the substituents have the abovementioned meanings.
The oxazole- and thiazolecarboxamides Ia and Ib according to the invention can be prepared in a variety of ways. They are obtained, for example, by the following processes:
1. Process for preparing compounds Ia and Ib where R.sup.2 is CO.sub.2 R.sup.5 and R.sup.5 is C.sub.1 -C.sub.6 -alkyl ##STR3##
These oxazole- and thiazolecarboxamides Ia and Ib are obtained by hydrolyzing a diester of the formula II in a conventional manner with one equivalent of an aqueous base to give the monoesters IIIa and IIIb and then separating IIIa and IIIb or initially converting the mixture to the halide or another active form of the carboxylic acid and subsequently amidating these derivatives with an amine IV. ##STR4##
The individual steps A and B in this reaction sequence can be carried out as follows: Step A:
The partial hydrolysis of the diester II to the monoesters IIIa and IIIb is normally carried out at from -20.degree. to 60.degree. C., preferably -10.degree. to 30.degree. C., in an inert organic solvent which is miscible with water, in the presence of from 1.0 to 1.2 mole equivalents of a base.
Particularly suitable bases are alkali metal hydroxides. The base is generally added as an aqueous solution which is from 5 to 20% strength.
Examples of preferred solvents for this reaction are dioxane or the alcohol corresponding to the ester component in the formula II.
The reaction mixture is normally worked up by acidification, when the desired product separates out as a solid or oil. Isolation is carried out in a conventional manner by filtration or extraction.
The mixture of the two isomeric monoesters IIIa and IIIb can be separated by fractional crystallization or chromatography, or it can be reacted further without separation.
Step B:
The compounds Ia and Ib are obtained from the monoesters IIIa and IIIb by initially converting the latter in a conventional manner into the halide or another active form of the carboxyl group and subsequently amidating these derivatives with an amine IV.
Examples of active forms of carboxylic acids are, besides the halides such as, in particular, the chlorides and bromides, also the imidazolides. The halides are generally preferred.
They are obtained by reacting the carboxylic acids IIIa and IIIb with a halogenating agent such as thionyl chloride or bromide, phosphorus oxychloride or oxybromide, trichloride or tribromide or pentachloride or pentabromide, phosgene and elemental chlorine and bromine.
From 1 to 5 mole equivalents, preferably from 1 to 2 mole equivalents, of halogenating agent are used.
The reaction is carried out at from 0.degree. C. to the boiling point of the halogenating agent or, if an inert organic solvent is used, the boiling point thereof, preferably at from 20.degree. to 120.degree. C.
Examples of suitable solvents are hydrocarbons and halohydrocarbons such as tetrachloroethane, methylene chloride, chloroform, dichloroethane, chlorobenzene, 1,2-dichlorobenzene, benzene, toluene and xylene.
The active carboxylic acid derivatives are normally isolated, for example by removing the halogenating agent and, where present, the solvent by distillation and only then reacting them with the amines IV.
In this case, the amidation is carried out from -20.degree. to 100.degree. C., preferably at -10.degree. to 20.degree. C., in an inert aprotic polar organic solvent.
Particularly suitable solvents for this reaction are halohydrocarbons such as dichloromethane, and ethers such as diethyl ether and tert-butyl methyl ether.
Since hydrogen halide is formed in the amidation of acid halides, it is advisable to add the amine IV in an excess of from 2 to 5 mole equivalents, preferably 2 to 3 mole equivalents. If the amine is used in equimolar amount (from 1 to 1.2 mole equivalents), a base should be added, especially a tertiary amine such as triethylamine or pyridine, to bind the hydrogen halide.
When a mixture of the monoesters IIIa and IIIb is used as starting material, the reaction results in a mixture of the isomeric carboxamides Ia and Ib. This mixture can be fractionated into the individual components in a conventional manner, for example by fractional crystallization or chromatography.
The precursors II required for this synthesis are known (Bull. Soc. Chim. Fr. 1974, 2079) or can be obtained by known methods (Bull. Soc. Chim. Fr. 1969, 1762; J. Chem. Soc., 1953, 93).
2. Process for preparing compounds Ia and Ib where X is sulfur and R.sup.2 is CO.sub.2 H ##STR5##
These thiazolecarboxamides Ia and Ib are obtained particularly advantageously by reacting a dicarboxylic anhydride of the formula V in a conventional manner with an amine of the formula IV to give the isomers Ia and Ib and subsequently fractionating the mixture to give the isomers ##STR6##
The reaction is normally carried out at from -10.degree. to 150.degree. C., preferably 20.degree. to 120.degree. C., in an inert aprotic polar organic solvent.
Particularly suitable solvents are halohydrocarbons, e.g. tetrachloroethane, methylene chloride, chloroform, dichloroethane, chlorobenzene and 1,2-dichlorobenzene; ethers, e.g. diethyl ether, methyl tertbutyl ether, dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxan; dipolar aprotic solvents, e.g. acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone and 1,3-dimethylimidazolidin-2-one; aromatic compounds, e.g. benzene, toluene, xylene, pyridine and quinoline; ketones, e.g. acetone, methyl ethyl ketone or mixtures thereof.
The amine IV is generally used in equimolar amounts or in an excess, preferably in amounts of from 1.0 to 5.0 mole equivalents based on V.
The dicarboxylic anhydrides required for this process as known or can be prepared by known methods (Bull. Soc. Chim. Fr. 1969, 1762; CS-A-195,369; CS-A-195,370).
3. Process for preparing compounds Ia and Ib where R.sup.1 is not halogen and R.sup.2 is carboxyl or formyl ##STR7##
These isomeric oxazole- and thiazolecarboxamides are obtained by activating and amidating a carboxylic acid IIIc or IIId under the conditions described in 1B, and then reacting the resulting amides VIa and VIb in a conventional manner in the presence of a carboxylating or formylating reagent. ##STR8##
Step A in this reaction sequence is generally carried out under the conditions described in Section B in Process 1. Step B.
The carboxylation or formylation of the oxazole- and thiazolecarboxamides VIa and VIb is usually carried out at from 0.degree. to -100.degree. C., preferably -50.degree. to 80.degree. C., in an inert aprotic polar organic solvent in the presence of a base with exclusion of moisture.
The preferred carboxylating agent is gaseous or solid carbon dioxide, and dimethylformamide or N-formylmorpholine is used, in particular, as formylating reagent.
Suitable solvents are, in particular, ethers, e.g. diethyl ether, methyl tert-butyl ether, dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxan.
The bases which are preferably used are organometallic compounds, e.g. methyllithium, n-butyllithium, s-butyllithium, t-butyllithium or phenyllithium.
The reaction is normally carried out by first adding up to 3 mole equivalents of the dissolved base to a solution of the oxazole- or thiazolecarboxamide VIa or VIb, resulting in a derivative which is metalated on the heterocycle and is then converted into the desired product Ia or Ib by addition of the electrophilic carboxylating or formylating reagent.
When R.sup.3 is hydrogen, correspondingly more mole equivalents of the base are required because, in this case, the amide nitrogen is initially deprotonated. Hence, from 2 to 2.5 mole equivalents of the base are preferably used for the reaction of carboxamides VIa or VIb where R.sup.3 is hydrogen.
Compounds VIa and VIb where R.sup.1 is hydrogen react with the base initially to metalate the 2-position of the heterocycle ring.
In order to introduce the carboxyl or formyl radical adjacent to the carbamoyl group in this case, it is necessary to start from oxazole- or thiazolecarboxamides VIa or VIb where R.sup.3 is hydrogen.
Oxazole- and thiazolecarboxamides Ia and Ib where R.sup.1 is hydrogen and R.sup.3 is not hydrogen are obtained from the compounds which can be obtained by the abovementioned process and in which R.sup.1 and R.sup.3 are hydrogen in a conventional manner by subsequent alkylation or cycloalkylation.
The carboxylic acids IIIc and IIId required for the abovementioned process are known from the literature (Beilstein, Volume 27, Supplements 1-5) or can be prepared by conventional methods, for example by oxidation of the corresponding alcohols or aldehydes or by hydrolysis of the corresponding nitriles (J. V. Metzger in "The Chemistry of Heterocyclic Compounds, Vol. 34, Part 1, Thiazole and its Derivatives", Arnold Weissberger and Edward C. Taylor (Editors), John Wiley and Sons, pages 519 et sec., I. J. Turchi in "The Chemistry of Heterocyclic Compounds, Vol. 45, Oxazoles", Arnold Weissberger and Edward C. Taylor (Editors), John Wiley and Sons).
4. Process for preparing compounds Ia and Ib where R.sup.2 is carboxyl ##STR9##
These oxazole- and thiazolecarboxamides Ia and Ib are obtained, for example, by hydrolyzing an appropriate carboxamide Ia or Ib where R.sup.2 is CO.sub.2 R.sup.5 and R.sup.5 is C.sub.1 -C.sub.6 -alkyl in a conventional manner with one equivalent of an aqueous base. The reaction is shown in the following diagram only for the carboxamides Ia. It takes place similarly with the corresponding carboxamides Ib. ##STR10##
This synthesis is generally carried out under the conditions described in Section A in Process 1.
5. Process for preparing compounds Ia and Ib where R.sup.2 is COYR.sup.5 ##STR11##
These carboxamides Ia and Ib are obtained by activating a corresponding carboxylic acid Ia or Ib (R.sup.2 =CO.sub.2 H) and subsequent reaction in a conventional manner with a compound VII. ##STR12##
The reaction can be carried out at from -20.degree. C. to the reflux temperature of the solvent or mixture thereof, preferably at from 0.degree. to 60.degree. C.
Solvents expediently used for these reactions are halohydrocarbons, e.g. tetrachloroethane, methylene chloride, chloroform, dichloroethane, chlorobenzene and 1,2-dichlorobenzene; ethers, e.g. diethyl ether, methyl tert-butyl ether, dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxan; aromatic compounds, e.g. benzene, toluene or xylene; or mixtures thereof.

It is particularly preferred to use ethers such as diethyl ether, tetrahydrofuran or dioxan with propanephosphonic anhydride as condensing agent at from 20.degree. to 60.degree. C.
6. Process for preparing compounds Ia and Ib where R.sup.2 is 4,5-dihydro-2-oxazolyl ##STR13##
These compounds are obtained by reacting an appropriate carboxylic acid derivative Ia or Ib where R.sup.2 is CO.sub.2 R' or COOH and R' is C.sub.1 -C.sub.4 -alkyl in a conventional manner with an amino alcohol of the formula VIII. ##STR14##
The reaction is carried out at from 0.degree. to 180.degree. C., preferably at the reflux temperature of the mixture with an amino alcohol VIII, in the presence or absence of an inert solvent. The ratio of ester or carboxylic acid Ia or Ib to amino alcohol VIII in this reaction is from 1:1 to 1:2.5, preferably 1:1 to 1:1.5.
The solvents expediently used are halohydrocarbons such as chlorobenzene and 1,2-dichlorobenzene, ethers, e.g. methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxan; alcohols such as methanol, ethanol, propanol or ethylene glycol, dipolar aprotic solvents, e.g. acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone and 1,3-dimethylimidazolin-2-one, or aromatic compounds, e.g. benzene, toluene and xylene. The concentration of the precursors in these solvents is generally from 0.1 to 5.0 mol/l, preferably 0.2 to 2.0 mol/l.
The reaction is generally complete after 14 hours; the carboxamides Ia and Ib are then precipitated, where appropriate by adding water, filtered off with suction or extracted with an organic solvent, and purified by conventional methods such as recrystallization or chromatography.
Compounds of the formula VIa where R.sup.1 is --ZR.sup.8 are obtained in a conventional manner (Helv. Chim. Acta, 37 (1954) 2059) by reacting a 2-halothiazole-4-carboxamide VIa (DE 2,241,035) with an alcohol or thiol H--ZR.sup.8 in the presence of a base in an inert organic solvent. ##STR15##

The 2-halothiazole-5-carboxamides of the formula VIb required for the reaction can be obtained by methods known from the literature from the corresponding carbonyl halides by reaction with amines (U.S. Pat. No. 4,001,421
Compounds of the formula Ib can be obtained by reacting dicarboxylic esters of the formula II with amines in a conventional manner, and hydrolyzing the resulting amides Ib as shown in the scheme: ##STR17##
The procedure for this is expediently to dissolve the diester II in an inert organic solvent and react with an amine.
The solvents used for these reactions are ethers, e.g. diethyl ether, methyl tert-butyl ether, dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxan; aromatic compounds, e.g. benzene, toluene, xylene or mesitylene; alcohols, e.g. methanol, ethanol, iso-propanol and tert-butanol, or mixtures thereof.

The molar ratio of diester II to amine is from 1:1 to 1:2, preferably from 1:1 to 1:1.2.
The concentration of the precursors in the solvent is generally from 0.1 to 5 mol/l, preferably 0.2 to 2.0 mol/l.
It is particularly preferable to use alcohols such as ethanol in the presence of one equivalent of amine at from 50.degree. to 100.degree. C. The diesters II required for the reaction are known from the literature or can be prepared by conventional methods (Bull. Soc. Chim. Fr., 1969, 1762; J. Chem. Soc., 1953, 93).

The oxazole- and thiazolecarboxamides Ia' and Ib', or herbicidal 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 agents, or granules by spraying, atomizing, dusting, 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, 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 metal 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.
Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. 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 from 95 to 100, % (according to the NMR spectrum).
Compounds Ia and Ib according to the invention may be formulated for instance as follows:
I. 90 parts by weight of compound no. 1.003 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. 1.010 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 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.
III. 20 parts by weight of compound no. 1.004 is dissolved in a mixture consisting of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 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, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient.
IV. 20 parts by weight of compound no. 1.011 is dissolved in a mixture consisting of 25 parts by weight of cyclohexanone, 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, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient.
V. 20 parts by weight of compound no. 1.011 is well mixed with 3 parts by weight of the sodium salt of diisobutylnaphthalene-alpha-sulfonic acid, 17 parts by weight of the sodium salt of a lignin-sulfonic acid obtained from a sulfite waste liquor, and 60 parts by weight of powdered silica gel, and triturated in a hammer mill. By uniformly distributing the mixture in 20,000 parts by weight of water, a spray liquor is obtained containing 0.1% by weight of the active ingredient.
VI. 3 parts by weight of compound no. 1.003 is intimately mixed with 97 parts by weight of particulate kaolin. A dust is obtained containing 3% by weight of the active ingredient.
VII. 30 parts by weight of compound no. 1.004 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.
VIII. 20 parts by weight of compound no. 1.010 is intimately mixed with 2 parts of the calcium salt of dodecylbenzenesulfonic acid, 8 parts of a fatty alcohol polyglycol ether, 2 parts of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate and 68 parts of a paraffinic mineral oil. A stable 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).
The application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stages, and range from 0.001 to 5, and preferably from 0.01 to 2, kg/ha.
In view of the number of application methods possible, the compounds according to the invention, or agents containing them, may be used in a large number of crops for eliminating unwanted plant growth.
To increase the spectrum of action and to achieve synergistic effects, the oxazole- and thiazolecarboxamides Ia and Ib 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, triazinones, 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 compounds Ia and Ib, either alone or in combination with other herbicides, in admixture with other crop protection agents, e.g., agents for combating pests or phytopathogenic 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 oxazole- and thiazolecarboxamides of the formulae Ia' and Ib' 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 active ingredients, suspended or emulsified in water, were applied to the surface of the soil immediately after the seeds had be sown. 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 post-emergence 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 Cassia tora, Chenopodium album, Chrysanthemum coronarium, Ipomoea spp., Triticum aestivum and Veronica spp.
Active ingredients nos. 1.001, 1.003, 1.004, 1.009, 1.010, 1.011, 3.002, 3.005 and 3.024, applied postemergence at a rate of 1.0 kg/ha, provide excellent control of unwanted broadleaved plants. Compounds nos. 1.001, 1.003 and 1.009 are also tolerated by wheat. Compound no. 3.005 is excellently tolerated by Indian corn.
