However, the use of these compounds as herbicides is not known.
It is an object of the present invention to provide novel herbicidally active compounds.
We have found that this object is achieved by the carboxamides Ia, Ib, Ic and Id defined at the outset.
In addition, the present invention relates to processes for the preparation of these compounds, and to herbicides which contain compounds Ia, Ib, Ic and/or Id.
The novel carboxamides Ia, Ib, Ic and Id can be prepared by various processes, preferably by the following:
1. A process for the preparation of a compound of the formula Ia or Ib in which R.sup.2 is CO.sub.2 CH.sub.3 and X is oxygen ##STR6##
The carboxamide Ia or Ib is obtained by reacting the hydroxamyl chloride II in a conventional manner with a .beta.-keto ester III in the presence of a base, subsequently first hydrolyzing the resultant dimethyl diester IV using one equivalent of an aqueous base to give the monoester Va or Vb, and then converting Va or Vb, separately or as a mixture, first into the halide or another activated form of the carboxylic acid in a conventional manner and subsequently amidating this derivative using an amine VIa. ##STR7##
The individual reaction steps A, B and C of this synthesis can be carried out as follows:
Reaction step A:
The reaction is generally carried out at from 0.degree. to 50.degree. C., preferably from 10.degree. to 30.degree. C., in an inert, aprotic, polar organic solvent in the presence of a base.
The solvent used is expediently a hydrocarbon, such as, in particular, benzene, toluene, o-, m- or p-xylene, or an ether, such as diethyl ether, tert-butyl methyl ether, tetrahydrofuran, dimethoxyethane, ethylene glycol dimethyl ether or dioxane.
A particularly suitable base is sodium hydride.
The reaction is usually carried out by first converting the .beta.-keto ester III into the anion in the solvent containing from 1 to 2 mol equivalents of the base. This solution of the anion of III is subsequently treated with a solution of II, and the mixture is kept at the reaction temperature. The reaction is generally complete after from 4 to 12 hours.
Before work-up of the products, it is advisable to remove the water of reaction by azeotropic distillation.
Reaction step B:
The partial hydrolysis of the dimethyl diester IV to give the monoester Va or Vb is usually carried out at from -40.degree. to 20.degree. C., preferably from -20.degree. to 0.degree. C., in an inert, water-miscible organic solvent in the presence of from 1 to 1.1 mol equivalents of a base.
Particularly suitable bases are hydroxides of alkali metal cations. The base is generally added as a 5 to 10 percent strength aqueous solution.
Examples of preferred solvents for this reaction are tetrahydrofuran and dioxane.
For work-up, the reaction mixture is usually acidified, the desired product separating out as a solid or oil, and being isolated in a conventional manner by filtration or extraction.
The mixture of the two isomeric monoesters Va and Vb can be resolved by fractional crystallization or by chromatography or the reaction sequence can be continued without resolving the isomers.
Reaction step C:
The compound Ia or Ib is obtained form the monoester Va or Vb respectively by converting Va or Vb first into the halide or another activated form of the carboxylic acid function in a conventional manner and subsequently aminating this derivative using an amine VIa.
In addition to the halides, such as, in particular, the chlorides and the bromides, examples of activated forms of the carboxylic acid are also imidazolides. In general, the halides are preferred.
They are obtained by reacting the carboxylic acid Va or Vb with a halogenating agent, such as phosgene, thionyl chloride, thionyl bromide, phosphorus oxychloride, phosphorus oxybromide, phosphorus trichloride, phosphorus pentachloride, phosphorus tribromide, phosphorus pentabromide, elemental chlorine or elemental bromine.
The halogenating agent is employed in an amount of from 1 to 5 mol equivalents, preferably from 1 to 2 mol equivalents.
The reaction proceeds at from 20.degree. C. to the boiling point of the halogenating agent or, if using an inert organic solvent, to its boiling point.
Examples of suitable solvents are hydrocarbons, such as benzene, toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as dichloromethane, chloroform, 1,2-dichloroethane, 1,1,2,2-tetrachloroethane, chlorobenzene and 1,2-dichlorobenzene, and mixtures of these.
The activated carboxylic acid derivative is usually isolated, for example by removing the halogenating agent and, if present, the solvent by distillation and only then reacted with the amine VIa.
In this case, the amidation is carried out at from -20.degree. to 50.degree. C., preferably from 0.degree. to 30.degree. C., in an inert, aprotic, polar organic solvent
Particularly suitable solvents for this reaction are hydrocarbons, such as benzene, toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as dichloromethane, and ethers, such as dimethyl ether and tertbutyl methyl ether.
Since hydrogen halide is formed during the amidation of acyl halides, it is advisable to add the amine VIa in an excess of from 2 to 5 mole equivalents, preferably from 2 to 3 mole equivalents. If the amine is employed in an equimolar amount (from 1 to 1.2 mol equivalents), a base, in particular a tertiary amine, such as triethylamine or pyridine, should be added to bind the hydrogen halide.
If starting from a mixture of the monoesters Va and Vb, a mixture of the isomeric carboxamides Ia and Ib is obtained in the reaction. This mixture can be separated into the individual components in a conventional manner, for example by fractional crystallization or chromatography.
2. A process for the preparation of a compound Ia in which X is oxygen, R.sup.2 is CO--OR.sup.5 and R.sup.5 is not hydrogen or methyl: ##STR8##
In a similar manner to that outlined under 1., this compound Ia is obtained by reacting the hydroxamyl chloride II with a .beta.-keto ester of the formula IIIa in the above-outlined manner, subsequently cleaving the resultant diester IVa using a hydrolyzing agent to give the monoester Va', activating the latter and amidating product to give Ia. ##STR9##
Reaction steps A and C are carried out in general and specific terms under the conditions outlined for processes IA and IC.
Reaction step B:
The partial hydrolysis of the mixed diester IVa to give the monoester Va' is usually carried out at from -40.degree. to 20.degree. C., preferably from -20.degree. to 0.degree. C., in an inert organic solvent.
These processes are known in general terms and can be carried out under the conditions described in the literature.
If, in a synthesis of this type, a hydroxamyl chloride IIa is reacted with a .beta.-keto ester III, it is also possible specifically to prepare the compound Ib where X is oxygen, R.sup.2 is CO.sub.2 R.sup.5 and R.sup.5 is not hydrogen or methyl by the same route. ##STR10##
The last-mentioned process for the specific preparation of an isomer of the two carboxamides Ia and Ib is based on the possibility of selectively cleaving one ester group of the two different ester groups in a compound by using only one mole equivalent of hydrolyzing agent under mild reaction conditions.
Examples of suitable hydrolyzing agents are hydroxides of alkali metal cations in the case of unbranched alkyl esters, mineral acids in the case of .alpha.-branched alkyl esters, and hydrogen in the case of hydrogenolysis of benzyl and allyl esters.
3. A process for the preparation of a compound Ia or Ic in which R.sup.1 is not hydrogen, and R.sup.2 is carboxyl or formyl and R.sup.3 is hydrogen: ##STR11##
These isomeric carboxamides Ia and Ic are obtained activating and amidating a carboxylic acid Vc or Vd under the conditions outlined under 1C, and subsequently reacting the resultant amide VIIa or VIIb in a conventional manner in the presence of a carboxylating or formylating agent. ##STR12##
Reaction step A is carried out in general and specific terms under the conditions described under point C in process 1.
Reaction step B:
The formylation or carboxylation of the carboxamide VIIa (X.dbd.O or S) or VIIb (X.dbd.S) is generally carried out at from -100.degree. to 0.degree. C., preferably from -80.degree. to -20.degree. C., and the formylation or carboxylation of the carboxamide VIIb (X.dbd.O) is advantageously carried out at <-80.degree. C. The reaction is preferably carried out in an aprotic, polar, inert organic solvent with exclusion of moisture and in the presence of a base.
Particularly suitable formylating agents are dimethylformamide and N-formylmorpholine, and the preferred carboxylating agent is carbon dioxide.
Particularly suitable solvents are diethyl ether, tert-butyl methyl ether tetrahydrofuran and dioxane.
Preferred bases are alkali metal hydrocarbons, such as methyllithium, n-butyllithium, tert-butyllithium and phenyllithium.
The reaction is usually carried out by first adding from 2 to 2.5 mole equivalents of the dissolved base to a solution of the carboxamide VIIa or VIIb to produce a ring-metallated carboxamide derivative, which, on subsequent addition of the electrophilic formylating or carboxylating agent, reacts to form the desired product Ia or Ic.
The carboxylic acids Vc and Vd required for this process are known from the literature (Beilstein, main work and supplements 1-5, volume 27; R. W. Wiley, The Chemistry of Heterocyclic Compounds, Five- and Six-Membered Compounds with Nitrogen and Oxygen, Interscience Publishers, New York, London (1962), or can be prepared by methods known in general terms from the literature, for example by oxidizing the corresponding alcohol or aldehyde or by hydrolyzing the corresponding nitrile.
4. A process for the preparation of a compound of the formula Id in which R.sup.2 is COOR.sup.5 and R.sup.5 is hydrogen or C.sub.1 -C.sub.6 -alkyl, by hydrolyzing a dialkyl isoxazole- or isothiazole-4,5-dicarboxylate X (R.sup.5' .dbd.C.sub.1 -C.sub.6 -alkyl), converting the product into an acyl halide XII, and amidating the acyl chloride: ##STR13##
Particularly suitable isoxazole- or isothiazole- 4,5-dicarboxylates X are lower alkyl esters (R.sup.5 .dbd.R.sup.5' .dbd.C.sub.1 -C.sub.4 -alkyl), dimethyl and diethyl esters being particularly preferred.
The reaction is carried out by treating a dialkyl isoxazole- or isothiazole-4,5-dicarboxylate X in an organic solvent, eg. methanol or ethanol, at from about 0.degree. to 80.degree. C., preferably from 0.degree. to 50.degree. C., with in general about one equivalent of a strong base, eg. NaOH, KOH or Ca(OH).sub.2, in aqueous solution. When the reaction is complete, the mixture is cooled and acidified with a strong mineral acid, eg. hydrochloric acid or sulfuric acid. The resultant carboxylic acid XI can be isolated in a conventional manner, for example by suction filtration or by extraction with an organic solvent.
For conversion into the acyl halide XII, the carboxylic acid XI is reacted in a conventional manner with an inorganic acid halide, such as thionyl chloride, phosphorus trihalide or phosphorus pentahalide, the chlorides being preferred. The inorganic acid halide is expediently employed in an amount of from 1 to 5 mole equivalents, preferably from 1 to 2 mole equivalents. The reaction can be carried out without a solvent or in the presence of an inert organic solvent, eg. benzene or toluene, at from room temperature to the boiling point of the inorganic acid halide or the inert organic solvent. In some cases, the addition of a catalyst, such as dimethylformamide or 4-dimethylaminopyridine, may be advantageous. When the reaction is complete, the acyl halide XII can be isolated in a conventional manner, for example by removing the excess inorganic acid halide and organic solvent by distillation and subsequently distilling the acyl chloride XII at atmospheric pressure or reduced pressure.
The carboxamide of the formula Id in which R.sup.2 is COOR.sup.5 and R.sup.5 is C.sub.1 -C.sub.6 -alkyl is obtained from the acyl halide XII by reaction with an amine VIa, the acyl halide generally being reacted in an inert organic solvent, such as dichloromethane, or an ether, such as diethyl ether or methyl tert-butyl ether, with an amine VIa, likewise dissolved in an organic solvent. The amine VIa is expediently employed in from 2- to 5-times the molar amount, preferably from 2- to 3-times the molar amount, in order to bind the hydrogen halide produced. The reaction can also be carried out in the presence of an auxiliary base, such as a tertiary amine, eg. triethylamine. In this case, from 1 to 1.5 mole equivalents of the amine VIa are sufficient. The reaction temperature can be, for example, from 0.degree. to 50.degree. C., preferably from 0.degree. to 20.degree. C. The reaction is generally complete after from 1 to 12 hours. The mixture can be worked up in a customary manner, for example by hydrolyzing with water and subsequently extracting of the product of the formula Id (R.sup.2 .dbd.COOR.sup.5, R.sup.5 .dbd.C.sub.1 -C.sub.6 -alkyl) with an organic solvent and then evaporating the latter. The product of the formula Id (R.sup.2 .dbd.COOR.sup.5, R.sup.5 .dbd.C.sub.1 -C.sub.6 -alkyl) can be purified, for example, by recrystallization or chromatography.
The acid amide Id (R.sup.2 .dbd.COOR.sup.5, R.sup.5 .dbd.C.sub.1 -C.sub.6 -alkyl) can advantageously also be prepared from the carboxylic acid XI in one step, the carboxylic acid XI being reacted with an amine VIa at from 0.degree. to 50.degree. C., preferably from 5.degree. to 25.degree. C., in an inert solvent, such as dichloromethane, tetrahydrofuran, toluene or ethyl acetate, in the presence of a dehydrating agent, for example propanephosphonic anhydride (PPA) or dicyclohexylcarbodiimide (DCC).
The 4-alkoxycarbonylisoxazole-5-carboxamide or 4-alkoxycarbonylisothiazole-5-carboxamide Id (R.sup.2 .dbd.COOR.sup.5 where R.sup.5 .dbd.C.sub.1 -C.sub.6 -alkyl) can be converted into the free carboxylic acid Id (R.sup.2 .dbd.COOH), for example, by hydrolysis using an aqueous base and subsequently neutralizing the product using a mineral acid. The reaction is carried out by treating the ester Id (R.sup.2 .dbd.COOR.sup.5, R.sup.5 .dbd.C.sub.1 -C.sub.6 -alkyl) in an organic solvent, eg. methanol or ethanol, at from 0.degree. to 80.degree. C., preferably from 0.degree. to 50.degree. C., with a base, eg. NaOH, KOH or Ca(OH).sub.2. In general, from about 1 to 3 equivalents, preferably from 1 to 1.5 equivalents, of the strong base are employed in aqueous solution. When the reaction is complete, the mixture is acidified using a strong mineral acid, eg. hydrochloric acid or sulfuric acid, with cooling. The resultant carboxylic acid Id (R.sup.2 .dbd.COOH) can be isolated by suction filtration or by extraction with an organic solvent and evaporation of the latter. The product is further purified, for example, by recrystallization or chromatography.
10 5. A process for the synthesis of a dicarboxamide of the formula Ic in which R.sup.2 .dbd.CO--NR.sup.3 R.sup.4 (R.sup.3 and R.sup.4 .noteq.H), by reacting the acid Id' with a primary amine VIa in the presence of a dehydrating agent: ##STR14##
Examples of suitable dehydrating agents are propanephosphonic anhydride and dicyclohexylcarbodiimide. In general, the process is carried out at from -20.degree. to 50.degree. C., preferably from 20.degree. to 40.degree. C., in an inert organic solvent, such as dichloromethane or an ether, such as diethyl ether or methyl tert-butyl ether. The starting materials are reacted in approximately stoichiometric amounts. The mixture can be worked up in the cutomary manner, for example by hydrolysis using water, extraction of the product of the formula Ic (R.sup.2 .dbd.CO--NR.sup.3 R.sup.4) with an organic solvent, and evaporation of the latter. The product of the formula Ic (R.sup.2 .dbd.CO--NR.sup.3 R.sup.4) can be further purified, for example, by recrystallization or chromatography.
The resultant isoxazole-4,5-dicarboxamide of the formula Ic in which X is oxygen and R.sup.2 is CO--NR.sup.3 R.sup.4 (R.sup.3 and R.sup.4 .noteq.H) can be used to prepare the carboxylic acid Ic (R.sup.2 .dbd.COOH) by reaction with excess potassium tert-butoxide. This reaction is expediently carried out by treating the diamide Ic (R.sup.2 .dbd.CO--NR.sup.3 R.sup.4) in an inert organic solvent, such as diethyl ether or tetrahydrofuran, at from 0.degree. to 30.degree. C., preferably at room temperature, with potassium tert-butoxide in water (ratio 3 to 6:1). The reaction is generally complete after from 1 to 12 hours. The free carboxylic acid Ic (R.sup.2 .dbd.COOH) can be isolated, after acidification using a mineral acid, either by suction filtration or by extraction with an organic solvent and evaporation of the latter. The acid Ic (R.sup.2 .dbd.COOH) can be further purified by either recrystallization or chromatography.
The isothiazole-4,5-dicarboxylates X (X.dbd.sulfur) required as starting material for this process are known (R. M. Paton, J. Stobie, R. M. Mortier, Phosphorus Sulfur, 15 (2), (1983), 137, or can be prepared by conventional methods.
The dialkyl isoxazole-4,5-dicarboxylates X (X.dbd.oxygen) required as starting material for this process are known from the literature [J. Org. Chem. 43, (1978), 3736; Chem. Pharm. Bull. 28, (1980), 3296; Tetrahedron 30, (1974), 1365] or can be prepared by methods which are known in general terms from the literature [cf., for example, DE-A 27 54 832, and Synthesis, (1982), 508], for example from the aldoxime XIII and the acetylenedicarboxylate XIV: ##STR15##
In this process, the aldoxime XIII is oxidized in the reaction medium by the hypohalite to give the corresponding nitrile oxide, which is a very reactive 1,3-dipole. This nitrile oxide is continuously scavenged, as it is produced, by the acetylene dicarboxylate XIV, likewise present in the reaction medium, in a 1,3-dipolar cycloaddition reaction with formation of the isoxazole compound X.
Expediently, equimolar amounts of the aldoxime XIII and of the acetylenedicarboxylate XIV are reacted with the hypohalite, which can be added to the reaction mixture in a stoichiometric amount. However, it is usually metered into the reaction batch in a slight excess, up to a two-fold excess. For technical reasons, it may be advantageous to limit the conversion by using sub-stoichiometric amounts of hypohalite, from about 50 to 90 mol-% per mole of XIII. It is also possible to use sub- or super-stoichiometric amounts of the reactants XIII and XIV.
The hypohalites used are generally hypobromites or hypochlorites, of which the latter are preferred. For this purpose, aqueous solutions of hypochlorous or hypobromous acid may be employed, but alkali metal or alkaline earth metal hypochlorites or hypobromites, for example sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, strontium hypochlorite, barium hypochlorite or the corresponding hypobromides, are preferred. Particular preference is given to sodium hypochlorite, potassium hypochlorite and calcium hypochlorite, in the form of their commercially available, aqueous solutions.
Examples of suitable solvents for the process are alcohols, such as methanol, ethanol, propanol and isopropanol, ketones, such as acetone and methyl ethyl ketone, ethers, such as diethyl ether, methyl tert-butyl ether, tetrahydrofuran and dioxane, hydrocarbons, such as pentane, hexane, cyclohexane, petroleum ether, white oils and ligroin, halogenated aliphatic hydrocarbons, such as methylene chloride, chloroform, carbon tetrachloride, dichlorethane, trichloroethane, tetrachloroethane and perchloroethane, aromatic compounds, such as benzene, toluene, xylenes and chlorobenzenes, esters, such as ethyl acetate, and dimethylformamide, N-methylpyrrolidone, dimethyl sulfoxide, sulfolane, etc.
The temperature at which the reaction is carried out can be varied within broad limits. In general, it takes place even at -15.degree. C. and lower, and the upper limit is in principle set only by the boiling point of the solvent used, since the reaction is expediently carried out at atmospheric pressure. The preferred temperature range is from 0.degree. to 40.degree. C. The reaction can also be carried out under superatmospheric pressure, in particular under autogenous pressure, but atmospheric pressure is preferred.
The aldoximes XIII required for this process are either known or can be prepared in a conventional manner (eg. Houben-Weyl, Methoden der organischen Chemie, Vol. 10/4, pages 55 to 56, Thieme Verlag, Stuttgart, 1968) by reacting the corresponding aldehydes with hydroxylamine. The aldoximes XIII can of course be used either in the form of their E- or Z-isomers or as mixtures of these. The acetylenedicarboxylates are commercially available or can be prepared by conventional methods (eg. Organic Syntheses Coll. Vol. 4, page 329).
6. A process for the preparation of compounds Ia and Ib, in which R.sup.2 is carboxyl and X is sulfur: ##STR16##
These carboxamides Ia and Ib are particularly advantageously obtained by reacting an isothiazoledicarboxylic anhydride VIII in a conventional manner with an amine VIa, and separating the resultant mixture of isomers Ia and Ib into the individual components. ##STR17##
The reaction is usually carried out at from -10.degree. to 50.degree. C., preferably from 0.degree. to 30.degree. C., in an inert, aprotic, polar organic solvent.
Particularly preferred solvents are halogenated hydrocarbons, such as methylene chloride, and ethers, such as diethyl ether, tert-butyl methyl ether and tetrahydrofuran.
The amine VIa is generally employed in an equimolar amount or in an excess, preferably in an amount of from 1 to 1.2 mol equivalents, based on VIII.
In this process, the isomeric carboxamides of the formulae Ia and Ib (R.sub.2 =COOH) are produced in different amounts. The isomer mixture is resolved either by fractional crystallization or by chromatography.
The isothiazoledicarboxylic anhydrides VIII required for this process are known or can be prepared by conventional methods (Beilstein, Main Work and Supplements 1-5, Volume 27).
7. A process for the preparation of a compound Ia, Ib, Ic or Id, in which R.sup.2 is CO.sub.2 H: ##STR18##
These compounds Ia, Ib, Ic and Id are obtained by hydrolyzing the corresponding ester Ia, Ib, Ic or Id in which R.sup.2 is CO.sub.2 R.sup.5 and R.sup.5 is C.sub.1 -C.sub.4 -alkyl in a conventional manner in the presence of an aqueous base.
This ester hydrolysis is carried out under the general and specific conditions outlined for process 2 under point B.
8. A process for the preparation of compounds Ia, Ib, Ic and Id in which R.sup.2 is COYR.sup.5 or CONR.sup.6 R.sup.7 (shown as an example for the carboxamide Ia): ##STR19##
Expediently, a carboxylic acid Ia, Ib, Ic or Id (R.sup.2 =COOH) is reacted with an alcohol or thiol IX or with an amine VIb in the presence of a dehydrating agent, for example propane phosphonic anhydride (PPA) or dicyclohexylcarbodiimide (DCC), at from -20.degree. to 50.degree. C., preferably from 0.degree. to 40.degree. C., in particular from 20.degree. to 30.degree. C.
All the starting compounds are advantageously employed in an approximately stoichiometric ratio, but an excess of one or other component, approximately up to 10 mol-%, may also be advisable in some cases.
Expedient solvents are hydrocarbons, such as toluene and o-, m- and p-xylene, halogenated hydrocarbons, such as dichloromethane, and ethers, such as diethyl ether, tert-butyl methyl ether and tetrahydrofuran.
A variant of the process comprises activating the carboxylic acid Ia, Ib, Ic or Id (R.sup.2 =COOH) as described for process 1C, and subsequently esterifying or amidating the product without using a dehydrating agent.
The process is normally carried out at atmospheric pressure.
The amines VIb are known or can be prepared by conventional processes Some of the alcohols and thiols HY--R.sup.5 are known. If R.sup.5 is --CR.sup.10 .dbd.N--R.sup.11 -substituted C.sub.1 -C.sub.6 -alkyl (iminoalcohols XVI), these alcohols and thiols are novel; however, they can be prepared by one of the following known processes (shown as an example for Y.dbd.O and R.sup.5 .dbd.--CH.sub.2 -CR.sup.10 =N--R.sup.11 where R.sup.10 .dbd.H and R.sup.11 .dbd.C.sub.2 H.sub.5): ##STR20##
The following alcohols, for example, were prepared by the process mentioned:
HO--CH.sub.2 --CH.dbd.N--OCH.sub.3

HO--CH.sub.2 --CH.dbd.N--OCH.sub.2 --CH.dbd.CH.sub.2
HO--CH.sub.2 --C(CH.sub.3).dbd.N--OCH.sub.2 --C.sub.6 H.sub.5
HO--CH.sub.2 --C(CH.sub.3).dbd.N--OCH.sub.2 --CH.dbd.CH.sub.2
9. A process for the preparation of a compound Ia, Ib, Ic or Id in which R.sup.2 is 4,5-dihydrooxazol-2-yl, by the conventional reaction of a carboxamide Ia, Ib, Ic or Id where R.sup.2 is COOH or COOR.sup.5 (R.sup.5 =unsubstituted or substituted C.sub.1 -C.sub.4 -alkyl, as indicated under the radicals R.sup.5), with an aminoalcohol of the formula XV [cf. Wehrmeister, J. Org. Chem. 26, (1961), 3821]: ##STR21##
The reaction is carried out by reacting the compound at from 0.degree. to 180.degree. C., preferably under reflux temperature of the mixture used, with an aminoalcohol XV, if desired in the presence of an inert solvent. The ester or carboxylic acid and the aminoalcohol XV are employed in a ratio of from 1:1 to 1:2.5, preferably from 1:1 to 1:1.5.
The solvents expediently used are halogenated hydrocarbons, such as chlorobenzene and 1,2-dichlorobenzene, ethers, eg. 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, eg. acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone and1,3-dimethylimidazolin-2-one, or aromatic compounds, eg. benzene, toluene and xylene. 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 reaction is generally complete after 14 hours; the carboxamide Ia, Ib, Ic or Id (where R.sup.2 =4,5-dihydrooxazol-2-yl) is then precipitated, if necessary, by adding water, and filtered off with suction or extracted with an organic solvent, and purified by customary standard methods, such as recrystallization or chromatography.
The process is generally carried out at atmospheric pressure or under the autogenous pressure of the particular solvent.
10. A process for the preparation of a compound Ia; Ib, Ic or Id in which R.sup.2 is formyl: ##STR22##
The compound Ia, Ib, Ic or Id is obtained, for example, by activating a corresponding carboxamide of the formula Ia, Ib, Ic or Id where R.sup.2 is CO.sub.2 H, under the conditions outlined in the case of process 1, and reducing the resultant activated form of the carboxylic acid in a conventional manner.
The carboxylic acid is preferably converted into the corresponding chloride, which is reduced at from -100.degree. to 0.degree. C., in particular from -80.degree. to -50.degree. C., using a complex hydride, such as, in particular, lithium tri-t-butoxyaluminum hydride. Particularly preferred solvents in this case are ethers, such as dimethyl ether, diethyl ether, tetrahydrofuran, 1,2-dimethoxyethane, diethylene glycol dimethyl ether and dioxane (J. Am. Chem. Soc. 80, (1958), J. Am. Chem. Soc. 80, (1958), 5377).
11.

J. March, Advanced Organic Chemistry, Third Edition, John Wiley and Sons, 1985, pp. 735ff.).

The carboxamides Ia, Ib, Ic and Id, or herbicidal agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspension (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, 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 metal and ammonium salts of aromatic sulfonic acids, e.g., ligninsulfonic acid, phenolsulonic acid, naphthalene sulfonic 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, heptadeconals, 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 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 l to 1, kg/ha.
In view of the numerous application methods possible, the compounds according to the invention, or agents containing them, may be used in a large number of crops for removing unwanted plants. The crops which follow are given by way of example:

USE EXAMPLES
The herbicidal action of the carboxamides of the formulae Ia', Ib', Ic' and Id 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 been 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 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., Polygonum persicaria, Stellaria media and Triticum aestivum.
Compounds 3.002, 3.005, 3.006, 3.008, 3.016, 3.017, 3.018, 3.019, 3.020, 3.023, 3.028, 3.029, 3.037. 3.052, 3.053, 6.04, 6.05, 6.06 and 6.08, applied postemergence at a rate of 1 kg/ha, provided excellent control of unwanted broadleaved plants. The carboxamides 3.006, 3.016 to 3.020, 3.028, 3.029, 3.037, 3.052, 3.053, 6.04, 6.05, 6.06 and 6.08 were also well tolerated by graminaceous crops such as wheat, Indian corn and rice.
