Abstract

Benzoyl derivatives of the formula I ##STR1## where the substituents L, M, X, Y and n have the meaning given in claim 1 and PA1 Q for [sic] a cyclohexane-1,3-dione ring, which is linked in the 2-position, of the formula II, ##STR2## where R.sup.15, R.sup.16, R.sup.18 and R.sup.20 are hydrogen or C.sub.1 -C.sub.4 -alkyl, PA1 R.sup.19 is hydrogen, C.sub.1 -C.sub.4 -alkyl or a group --COOR.sup.14, PA1 R.sup.17 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.3 -C.sub.4 -cycloalkyl, it being possible for these groups, if desired, to carry one to three of the following substituents: halogen, C.sub.1 -C.sub.4 -alkylthio or C.sub.1 -C.sub.4 -alkoxy, or PA1 R.sup.17 is tetrahydropyran-3-yl, tetrahydropyran-4-yl or tetrahydrothiopyran-3-yl or PA1 R.sup.17 and R.sup.20 together form a bond or a three to six-membered carbocyclic ring, PA1 where in the case where Y=C.dbd.O, X is not equal to NR.sup.23, and agriculturally utilizable salts, a process for their preparation and their use as herbicides are described.
