[0001] The present invention relates to 1-phenylpyrrolidin-2-one-3-carboxa- mides and their agriculturally useful salts, to compositions comprising such compounds and to the use of the 1-phenylpyrrolidin-2-one-3-carboxami- des, of their salts or of compositions comprising them as herbicides.

[0002] WO 95/33719 describes 1-arylthiazolidinones, 1-aryloxazolidinones and 1-arylpyrrolidinones of the formula: where A is an aromatic or heteroaromatic radical, n is 0 or 1, x is in particular S, O or CH.sub.2, Y is in particular S, O, CH.sub.2 or CH(CH.sub.3) or a group NR.sup.6, Z is in particular NH or O, R.sup.1 is preferably selected from unsubstituted or substituted alkyl, alkenyl, alkynyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted phenyl, benzyl or hetaryl, acyl, alkoxycarbonylalkyl and silyl, R.sup.2 and R.sup.3 are in particular hydrogen and R.sup.6 is inter alia hydrogen, formyl, unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl or unsubstituted or substituted aryl.

[0003] WO 95/33718 describes 1-phenylpyrrolidinethiones having herbicidal activity which, in the 3-position of the pyrrolidinethione ring, contain a group O--C(O)--NR.sup.1R.sup.2 where R.sup.1R.sup.2 are, for example, hydrogen, an unsubstituted or substituted hydrocarbon radical or hetaryl, or together with the nitrogen atom to which they are attached form a heterocycle.

[0004] Furthermore, U.S. Pat. No. 4,874,422 discloses herbicidally active 1-phenylpyrrolidin-2-one-3-carboxamides of the formula A where X is hydrogen or halogen, Y and Z independently of one another are O or S, n is 0 or 1, R.sup.1 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, phenyl, halophenyl, benzyl, halobenzyl, or alkyl which is substituted by alkoxy, alkylthio, phenyl, hydroxyl or cyano, R.sup.2 is hydrogen or alkyl, R.sup.3 is alkyl or alkenyl and R.sup.4 is selected from the group consisting of hydrogen, halogen, methyl, trifluoromethyl, 1,1,2,2-tetrafluoroethyl, 1,1,2,2-tetrafluoroethyloxy, difluoromethoxy, trifluoromethoxy, methylsulfanyl, methylsulfinyl, methylsulfonyl, methoxyiminomethyl, methoxyimino-1-ethyl, benzyloxyiminomethyl and benzyloxyimino-1-ethyl.

[0005] The herbicidal activity of the 1-arylpyrrolidinones described in the prior art is not always satisfactory. Their selectivity for harmful plants is unsatisfactory, too. In particular, even at low application rates, such herbicides tend to interfere with the generation of chlorophyll even in crop plants, which is undesirable in principle and may lead to yield losses.

[0006] It is an object of the present invention to provide novel herbicidally active compounds which allow a better targeted control of unwanted plants than the known herbicides. Advantageously, the novel herbicides should be highly active against harmful plants. Moreover, high compatibility with crop plants is desirable. Moreover, the compounds should have no adverse effect on the chlorophyll synthesis in crop plants.

[0007] We have found that this object is achieved by 1-phenylpyrrolidin-2-one-3-carboxamides of the formula I defined below and their agriculturally useful salts: where the variables R.sup.1, R.sup.2, R.sup.3, X, Y, A, n, R.sup.a, R.sup.b, R.sup.c, R.sup.d and R.sup.e are as defined below: [0008] R.sup.1 is hydrogen, OH, Cl, Br, C.sub.1-C.sub.6-alkyl, C.sub.3-C.sub.6-cycloalkyl, C.sub.3-C.sub.6-alkenyl, C.sub.3-C.sub.6-alkynyl, C(O)R.sup.4 or OC(O)R.sup.4; [0009] R.sup.2 and R.sup.3 independently of one another are hydrogen, C.sub.1-C.sub.10-alkyl, C.sub.3-C.sub.10-cycloalkyl, C.sub.7-C.sub.10-polycycloalkyl, C.sub.3-C.sub.8-alkenyl, C.sub.3-C.sub.10-alkynyl, C.sub.5-C.sub.10-cycloalkenyl, C.sub.3-C.sub.8-cycloalkyl-C.sub.1-C.sub.4-alkyl, phenyl or 3- to 7-membered heterocyclyl, where the 9 last-mentioned groups may be unsubstituted, partially or fully halogenated and/or contain 1, 2 or 3 radicals selected from the group consisting of OH, CN, NO.sub.2, COOH, C.sub.1-C.sub.6-alkyl, C.sub.1-C.sub.6-haloalkyl, C.sub.1-C.sub.6-alkoxy, C.sub.1-C.sub.4-haloalkoxy, C.sub.2-C.sub.6-alkenyl, C.sub.2-C.sub.6-alkynyl, C.sub.1-C.sub.6-alkylthio, C.sub.1-C.sub.4-haloalkyl-thio, unsubstituted or substituted phenyl, COOR.sup.5, NR.sup.6R.sup.7, C(O)NR.sup.8SO.sub.2R.sup.13, C(O)NR.sup.8R.sup.9 and 3- to 7-membered heterocyclyl, and each heterocyclyl may contain 1, 2 or 3 heteroatoms selected from the group consisting of oxygen, nitrogen, sulfur, a group NR.sup.10 and a group SO.sub.2, and, if appropriate, 1, 2 or 3 carbonyl groups and/or thiocarbonyl groups as ring members; and/or may contain a ring-fused phenyl ring which is unsubstituted or substituted; or [0010] R.sup.2 and R.sup.3 with the group N-(A).sub.n to which they are attached form a saturated 3- to 7-membered heterocycle which, in addition to the nitrogen atom, may contain 1, 2 or a further 3 heteroatoms selected from the group consisting of oxygen, nitrogen, sulfur and a group NR.sup.10 and, if appropriate, 1, 2 or 3 carbonyl groups and/or thiocarbonyl groups as ring members; [0011] R.sup.a, R.sup.b, R.sup.c, R.sup.d and R.sup.e independently of one another are hydrogen, OH, CN, NO.sub.2, halogen, C.sub.1-C.sub.10-alkyl, C.sub.3-C.sub.6-cycloalkyl, C.sub.2-C.sub.6-alkenyl, C.sub.2-C.sub.6-alkynyl, C.sub.1-C.sub.6-haloalk- yl, C.sub.2-C.sub.6-haloalkenyl, C.sub.1-C.sub.6-alkoxy, C.sub.1-C.sub.4-haloalkoxy, C.sub.1-C.sub.6-alkylthio, C.sub.1-C.sub.4-haloalkylthio, C(O)R.sup.4, COOR.sup.5, NR.sup.6R.sup.7, C(O)NR.sup.8R.sup.9, S(O).sub.2NR.sup.8R.sup.9, S(O)R.sup.11, S(O).sub.2R.sup.11 or C.sub.1-C.sub.4-alkoxy-C.sub.1-C.sub.6-alkyl; or [0012] two adjacent radicals R.sup.a to R.sup.e together with the atoms to which they are attached form a 5-, 6- or 7-membered saturated or unsaturated ring which may contain one or two heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur and a group NR.sup.10 as ring-forming atom and/or may carry one, two, three or four radicals selected from the group consisting of halogen and C.sub.1-C.sub.4-alkyl; [0013] X, Y independently of one another are oxygen or sulfur; [0014] n is 0 or 1; [0015] A is O, S(O).sub.k or NR.sup.12, where k is 0, 1 or 2; [0016] R.sup.4, R.sup.8, R.sup.9 independently of one another are hydrogen or C.sub.1-C.sub.4-alkyl; [0017] R.sup.5, R.sup.11 are C.sub.1-C.sub.4-alkyl; [0018] R.sup.6, R.sup.7 independently of one another are hydrogen, C.sub.1-C.sub.6-alkyl, C.sub.3-C.sub.6-alkenyl, C.sub.3-C.sub.6-alkynyl, C(O)R.sup.4, COOR.sup.5 or S(O).sub.2R.sup.11; [0019] R.sup.10, R.sup.12 independently of one another are hydrogen, C.sub.1-C.sub.6-alkyl, C.sub.3-C.sub.6-alkenyl or C.sub.3-C.sub.6-alkynyl- ; and [0020] R.sup.13 is phenyl which is unsubstituted or carries 1, 2, 3 or 4 substituents, where the substituents are selected from the group consisting of halogen, nitro, cyano, OH, alkyl, alkoxy, haloalkyl, haloalkoxy, COOR.sup.5, NR.sup.6R.sup.7 and C(O)NR.sup.8R.sup.9.

[0026] Depending on the substitution pattern, the compounds of the formula I may contain one or more centers of chirality, in which case they are present as mixtures of enantiomers or diastereomers. The invention provides both the pure enantiomers or diastereomers and their mixtures. The invention also provides tautomers of compounds of the formula I.

[0027] If R.sup.1 represents hydrogen, the 1-phenylpyrrolidin-2-one-3-carb- oxamides of the formula I according to the invention can be present in the form of their agriculturally useful salts.
