Abstract:
A 2-aroylcyclohexanedione of the formula I ##STR15## where the variables have the following meanings: R.sup.1 is hydrogen;R.sup.2, R.sup.3 and R.sup.4 independently of one another are hydrogen or C.sub.1 -C.sub.4 -alkyl;R.sup.5 is hydrogen, C.sub.1 -C.sub.4 -alkyl or (C.sub.1 -C.sub.4 -alkoxy)carbonyl;R.sup.6 and R.sup.7 independently of one another are C.sub.1 -C.sub.4 -alkyl, benzyl or together are an ethylene or propylene chain, where each methylene unit may carry one or two C.sub.1 -C.sub.4 -alkyl radicals;X and Y are oxygen;Ar is phenyl, which carries from one to four substituents selected from the group consisting of halogen cyano, nitro, --N.dbd.N--Ph, (C.sub.1 -C.sub.4 -alkoxy)carbonyl, --N(R.sup.9)--COR.sup.10, --N(R.sup.9)--SO.sub.2 --R.sup.11, --SO.sub.2 --N(R.sup.9)R.sup.10, --S(O).sub.m --R.sup.8, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkyl and C.sub.1 -C.sub.4 -haloalkoxy, where the four last-mentioned radicals in turn may carry one or two of the following substituents: C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio and/or cyano;Ph is phenyl which may carry one to three substituents selected from the group consisting of halogen, cyano, nitro, --S(O).sub.n --R.sup.23, (C.sub.1 -C.sub.4 -alkoxy)carbonyl, --SO.sub.2 --N(R.sup.24)R.sup.25, --N(R.sup.24)--COR.sup.25, --N(R.sup.24)--SO.sub.2 R.sup.26, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkyl and C.sub.1 -C.sub.4 -haloalkoxy, where the four last-mentioned radicals in turn may carry one or two of the following substituents: C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio and/or cyano;m and n independently of one another are 0, 1 or 2;R.sup.8 and R.sup.23 independently of one another are C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -haloalkyl, which both may carry one or two C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio and/or cyano radicals;R.sup.9, R.sup.10, R.sup.24 and R.sup.25 independently of one another are hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl or phenyl, which may carry one to three halogen, C.sub.1 -C.sub.4 -alkyl, and/or C.sub.1 -C.sub.4 -alkoxy radicals;R.sup.11 and R.sup.26 independently of one another are C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -haloalkyl, both may carry one or two cyano, phenyl and/ or benzyl radicals;or an agriculturally utilizable salt of I or an ester of I with a C.sub.1 -C.sub.10 -carboxylic, sulfonic or phosphonic acid or inorganic acid.
