| abstract |
The invention concerns benzoyl derivatives of formula (I) in which the variables have the following meanings: R<1>, R<2>: hydrogen, nitro, halogen, cyano, alkyl, alkyl halide, alkoxy, alkoxy halide, alkylthio, alkylthio halide, alkylsulphinyl, alkylsulphinyl halide, alkylsulphonyl, or C1-C6 alkylsulphonyl halide; R<3>: hydrogen, halogen or alkyl; R<4>, R<5>: hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylthio, dialkylamino, phenyl or carbonyl, wherein the six last-mentioned groups can be substituted; X: O, S, NR<9>, CO or CR<10>R<11>; Y: O, S, NR<12>, CO or CR<13>R<14>; R<15>: optionally substituted pyrazole which is bonded in position 4 and carries a hydroxy or sulphonyloxy group in position 5. The invention also concerns: the salts of these 3-heterocyclyl-substituted benzoyl derivatives which can be used for agricultural purposes; processes and intermediate products for preparing these substances; agents containing them; and the use as herbicides of these derivatives or agents containing them. |
