2-Benzoyl-cyclohexan-1,3-diones, of formula (I) that have herbicidal activity, as well as their salts for use in agriculture are described. They also disclose the procedures and intermediates for preparing the compounds of laformula (I), the herbicidal compositions containing them and their preparation, as well as the application of these derivatives or of the compositions containing them to combat harmful plants. In formula (I) the variables have the following meaning: R1, R2 are hydrogen, nitro, halogen, cyano, thiozinate, C1-C6-alkyl, C1-C6-halogenoalkyl, C1-C6-alkoxy-C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, -OR5, -OCOR6, -OSO2R6, -SH, -S (O) nR7, -SO2OR5, -S02NR5R8, -NR8S O2R6 or -NR8COR6; R3 is hydrogen C1-C6-alkyl, C1-C6-halogenoalkyl, C3-C6-alkenyl or C3-C6-alkynyl; R4 is hydrogen, C1-C6-alkyl, C3-C6, -cycloalkyl, C3-C6alkenyl, C4-C6-cycloalkenyl, C3-C6-alkynyl. -COR9, -CO2R9, -COSR9 or -CONR8 R9, where said alkyl, cycloalkyl, alkenyl, cycloalkenyl and alkynyl radicals, as well as R9 of the radicals -COR9, -CO2R9, -COSR9 and -CONR8R9 can be partially or completely halogenated and / or carry one of the following three groups defined in the description: X is oxygen or sulfur Z-oxygen or NR8; m 0 or 1; n 0, 1 or 2; and Q is a cyclohexane-1,3-dione ring attached at position 2, optionally substituted; where m means 1 when R3 is hydrogen. |
