The invention relates to novel aryl ketones of general formula (I), wherein n represents the numbers 0, 1 or 2, A represents alkanediyl (alkylene), R1 represents one of the following groupings, m, R5, R6, R7, R8, R9, R10, R11, R12 and R13 having one of the meanings given in the description, R2 represents hydrogen, nitro, cyano, carboxy, carbamoyl, thiocarbamoyl, halogen, or optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino or dialkylaminosulfonyl, R3 represents nitro, cyano, carboxy, carbamoyl, thiocarbamoyl, halogen or optionally substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, dialkylamino or dialkylaminosulfonyl and R4 represents an optionally substituted 4- to 12- membered, saturated or unsaturated, monocyclic or bicyclic, heterocyclic grouping. The invention also relates to methods for producing said substituted arylketones, to intermediate products and to the use of these compounds as herbicides.

L'invention concerne de nouvelles arylcétones substituées de formule générale (I) dans laquelle n est égal à 0, 1 ou 2, A désigne un alcanediyle (alkylène), R?1¿ désigne l'un des groupements (II) à (V), où m, R?5¿, R?6¿, R?7¿, R?8¿, R?9¿, R?10¿, R?11¿, R?12¿ et R?13¿ ont les significations données dans la description, R?2¿ désigne l'hydrogène, un nitro, cyano, carboxy, carbamoyle, thiocarbamoyle, un halogène, ou encore, un alkyle, alcoxy, alkylthio, alkylsulfinyle, alkylsulfonyle, alkylamino, dialkylamino ou dialkylaminosulfonyle, chacun d'eux étant éventuellement substitué, R?3¿ désigne un nitro, cyano, carboxy, carbamoyle, thiocarbamoyle, halogène, ou encore, un alkyle, alcoxy, alkylthio, alkylsulfinyle, alkylsulfonyle, alkylamino, dialkylamino ou dialkylaminosulfonyle, chacun d'eux étant éventuellement substitué et R?4¿ désigne un groupement hétérocyclique, monocyclique ou bicyclique, saturé ou insaturé, de 4 à 12 chaînons, éventuellement substitué. L'invention concerne en outre un procédé de fabrication de ces composés, ainsi que des produits intermédiaires, et l'utilisation de ces composés comme herbicides.
