| abstract |
The invention relates to novel substituted aryl ketones of the general formula (I) n n n in which n n represents the number 0, 1 or 2, n A represents alkanediyl (alkylene), n R 1 represents one of the groupings below n n n where n m, R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 each have one of the meanings given in the description, n R 2 represents hydrogen, nitro, cyano, carboxyl, carbamoyl, thiocarbamoyl, halogen, or represents in each case optionally substituted alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, dialkylamino or dialkylaminosulphonyl, n R 3 represents nitro, cyano, carboxyl, carbamoyl, thiocarbamoyl, halogen, or represents in each case optionally substituted alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, dialkylamino or dialkylaminosulphonyl, and n R 4 represents an optionally substituted 4- to 12-membered, saturated or unsaturated, monocyclic or bicyclic heterocyclic grouping, n and to processes for their preparation, to intermediates and to the use of these compounds as herbicides. |
