The invention relates to novel substituted benzoyl ketones of the formula (I) in which n represents 0, 1, 2 or 3, A represents a single bond or represents alkanediyl (alkylene), R1represents hydrogen or represents in each case optionally substituted alkyl or cycloalkyl, R2represents hydrogen, cyano, carbamoyl, halogen, or represents in each case optionally substituted alkyl, alkoxy, alkoxycarbonyl, alkylthio, alkylsulphinyl or alkylsulphonyl, R3represents hydrogen, nitro, cyano, carboxyl, carbamoyl, thiocarbamoyl, halogen, or represents in each case optionally substituted alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, dialkylamino or dialkylaminosulphonyl, R4represents nitro, cyano, carboxyl, carbamoyl, thiocarbamoyl, halogen, or represents in each case optionally substituted alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, dialkyiamino or dialkylaminosulphonyl, and Z represents an optionally substituted 4- to 12-membered, saturated or unsaturated, monocyclic or bicyclic, heterocyclic grouping which, contains 1 to 4 hetero atoms (up to 4 nitrogen atoms and optionally—alternatively or additionally—one oxygen atom or one sulphur atom, or one SO grouping or one SO2grouping) and which additionally contains one to three oxo g of the heterocycle roups (C═O) and/or thioxo groups (C═S) as components, of the heterocycle, and to processes for their preparation and to their use as herbicides.
