Abstract

Substituted 2-benzoylcyclohexane-1,3-diones of the formula I where:R1 and R2 are each hydrogen, mercapto, nitro, halogen, cyano, thiocyanato, C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-alkoxy, C2-C6-alkenyl, C2-C6-alkynyl, —OR3, —OCOR3, —OSO2R3, —S(O)nR3, —SO2OR3, —SO2N(R3)2, —NR3SO2R3 or —NR3COR3;R3 is hydrogen, C1-C6-alkyl, C1-C6-haloalkyl, C2-C6-alkenyl, C2-C6-alkynyl, phenyl or phenyl-C1-C6-alkyl; where the abovementioned alkyl radicals may be partially or fully halogenated and/or may carry one to three of the following groups:hydroxyl, mercapto, amino, cyano, R3, —OR3, —SR3, —N(R3)2, ═NOR3, —OCOR3, —SCOR3, —NR3COR3, —CO2R3, —COSR3, —CON(R3)2, C1-C4-alkyliminooxy, C1-C4-alkoxyamino, C1-C4-alkylcarbonyl, C1-C4-alkoxy-C2-C6-alkoxycarbonyl, C1-C4-alkylsulfonyl, heterocyclyl, heterocyclyloxy, phenyl, benzyl, hetaryl, phenoxy, benzyloxy and hetaryloxy, where the eight last mentioned radicals may in turn be substituted;n is 0, 1 or 2;Q is a cyclohexane-1,3-dione ring with or without substitution which is attached in position 2;X1 is a straight-chain or branched C1-C6-alkylene, a C2-C6-…
