摘要

1. A herbicidally active substituted diphenyl ether derivative of the formula I see diagramm : EP0005709,P15,F7 wherein R1 is a methyl group, R2 is halogen, the nitro or cyano group, R3 is halogen, C1 -C4 alkyl or the nitro group, R4 and R5 , each independently of the other, are hydrogen, CF3 , CN or NO2 , R6 is halogen, m is an integer from 0 to 3, X and Y, each independently of the other, are an oxygen or sulfur atom, Z is halogen or a -OH, -SH, -OR7 , see diagramm : EP0005709,P15,F1 or see diagramm : EP0005709,P15,F3 wherein R7 is alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, phenyl or benzyl, which radicals can also be substituted by halogen, CF3 , NO2 , CN, alkyl, alkoxy, alkylthio, -OH, NH2 , alkylamino, dialkylamino, and/or alkoxycarbonyl, and R7 can also be a -CONH-alkyl, -CO-NH-aryl, -CO-N(dialkyl), -CO-aryl or -CO-alkyl group, the alkyl and aryl moieties of which can additionally be substituted by halogen, and R7 can finally also be a radical see diagramm : EP0005709,P15,F5 in which the recurring or non-recurring substituent R10 can be the same or different and is halogen, NO2 , CN, CF3 or alkyl, Q is =CH- or =N- and n is 0, 1 or 2, and R8 and R9 , each independently of the other, are hydrogen, C1 -C4 alkyl which can be unsubstituted or substituted by halogen, CN, -OH or C1 -C4 -alkoxy, or R8 and R9 , together with the adjacent nitrogen atom, form a 5- to 6-membered heterocyclic ring which can additionally contain an oxygen, sulfur or further nitrogen atom as second heteroatom and can be substituted by C1 -C4 alkyl or phenyl, or wherein Z is one of the groups -O-CO-O-C2 H5 , -O-SO2 -CH3 or -O-SO2 -p-tolyl, if at the same time R2 is chlorine, (R6 )m is 2-chlorine, (R3 )m and R5 are hydrogen, R4 is 4-trifluoromethyl and X and Y are oxygen, or Z is the radical -O-CO-N(CH3 )OCH3 , if at the same time R2 is chlorine, (R6 )m is 2-chlorine, (R3 )m is 4-chlorine, R5 is hydrogen, R4 is 4-trifluoromethyl, and X and Y are oxygen, or at the same time R2 is nitro, (R6 )m is 2-chlorine, (R3 )m and R5 are hydrogen, R4 is 4-trifluoromethyl and X and Y are oxygen.
