CA 2373076
The invention relates to novel substituted benzoyl ketones of formula (I), wherein n represents 0, 1, 2 or 3; A represents a simple bond or alkanediyl (alkylene); R1 represents hydrogen or optionally substituted alkyl or cycloalkyl; R2 represents hydrogen, cyano, carbamoyl, halogen, or optionally substituted alkyl, alkoxy, alkoxycarbonyl, alkylthio, alkylsulfinyl or alkylsulfonyl; R3 represents hydrogen, nitro, cyano, carboxy, carbamoyl, thiocarbamoyl, halogen or optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino or dialkylaminosulfonyl; R4 represents nitro, cyano, carboxy, carbamoyl, thiocarbamoyl, halogen or optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino or dialkylaminosulfonyl; and Z represents an optionally substituted 4 to 12- membered, saturated or unsaturated, monocyclic or bicyclic, heterocyclic grouping containing 1 to 4 hetero atoms (up to 4 nitrogen atoms and optionally, - alternatively or additionally - an oxygen atom or a sulphur atom, or an SO2 grouping), which also contains one to three oxo-groups (C=O) and/or thioxo-groups (C=S) as constituents of the heterocycle. The invention also relates to methods for producing the inventive substituted benzoyl ketones and to their use as herbicides.
