摘要

2-aroylcyclohexandiones have general formula (I), in which X, Y stand for O or S; Ar stands for phenyl or heteroaryl with 1 to 4 substituents; or two adjacent carbon atoms of the phenyl or heteroaryl ring may also be bridged by a chain; R1, R2, R3, R4 stand for hydrogen or C1-C4-alkyl; R5 stands for H, C1-C4-alkyl or C1-C4-alkoxycarbonyl; R6, R7 stand for C1-C4-alkyl, benzyl or stand together for an optionally substituted ethylene or propylene chain. Also disclosed are the salts and esters of these compounds with acids, except for 2-(4-chloro-2-nitrobenzoyl)-5-dimethoxymethyl-5-methyl-cyclohexan-1,3-di one, and their use as herbicides and growth regulators.
