- 2. A 1-cycloalkylpyrazolylbenzoyl derivative of the formula I as claimed in claim 1 whereR1 is nitro, halogen, C1-C4-alkyl or C1-C4-alkoxy; R4 is halogen, nitro, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy, C1-C4-alkylthio or C1-C4-alkylsulfonyl.
- 3. A 1-cycloalkylpyrazolylbenzoyl derivative of the formula I as claimed in claim 1, whereR1 is halogen, C1-C4-alkyl or C1-C4-alkoxy; R4 is C1-C4-alkylsulfonyl; R13 is C3-C6-cycloalkyl.
- 4. A 1-cycloalkylpyrazolylbenzoyl derivative of the formula I as claimed in claim 1, whereR5 is hydrogen.
- 5. A process for preparing 1-cycloalkylpyrazolylbenzoyl derivatives of the formula I where R12=hydroxyl as claimed in claim 1, which comprises acylating a pyrazole of the formula II with an activated benzoic acid IIIa or a benzoic acid IIIb, where the variables X, Y, R1 to R5 and R13 to R14 are as defined in claim 1 and L1 is a nucleophilically displaceable leaving group, rearranging the acylation product in the presence or the absence of a catalyst to give the compounds of the fornula I where R12 is hydroxyl, and, optionally, to prepare 1-cycloalkylpyrazolylbenzoyl derivatives of the formula I where R12 hydroxyl by reacting the product with a compound of the formula VIL3—R12a VI whereL3 is a nucleophilically displaceable leaving group; R12a is C1-C6-alkyl, C3-C6-alkenyl, C1-C6--alkylsulfonyl, C1-C6--alkylcarbonyl, phenylsulfonyl or phenylcarbonyl, where the phenyl radical of the two last-mentioned substituents may be partially or fully halogenated and/or may carry one to three of the following groups: nitro, cyano, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy or C1-C4-haloalkoxy.
- 6. A composition comprising a herbicidally effective amount of at least one 1-cycloalkylpyrazolylbenzoyl derivative of the formula I or an agriculturally useful salt of I as claimed in claim 1 and auxiliaries which are customarily used for formulating crop protection agents.
- 7. A method for controlling undesirable vegetation, which comprises allowing a herbicidally effective amount of at least one 1-cycloalkylpyrazolylbenzoyl derivative of the formula I or an agriculturally useful salt of the compound of formula I as claimed in claim 1 to act on plants, their habitat or seeds, or on their habitat and seeds.
