摘要

Substituted triazolinones of formula (I) are disclosed, in which R1, R2 represent C1-C6 alkyl or C1-C6 alkyl halide; R3 represents H or a halogen; R4 represents CN, a halogen, C1-C6 alkyl, C1-C6 alkyl halide, C1-C6 alkoxy or C1C6 alkoxyl halide; R5 represents NO2, CN or hydrogen; R6 represents -OR7, SR7, -N(R8)-R9 or -N(R8)-OR10; R7 represents H, C1-C6 alkyl, C3-C6 alkenyl, C3C6 alkinyl, C3-C6 cycloalkyl, C1-C6 alkyl halide, cyano-C1-C6 alkyl, C1-C6 alkoxy-C1-C6-alkyl, C1-C6 alkylthio-C1-C6-alkyl, C1-C6 alkoxycarbonyl-C1-C6-alkyl, C1-C6-alkylaminocarbonyl-C1-C6-alkyl, Di-(C1-C6-alkyl)-aminocarbonyl-C1-C6 alkyl, C1-C6 alkyloxyamino-C1-C6 alkyl, Di-(C1-C6-alkoxy)-C2-C6-alkyl, Di (C1-C6-alkylthio)-C2-C6 alkyl, C3-C6 alkenyl halide, (as required) substituted phenyl or benzyl; R8, R9, R10 represent C1-C6 alkylcarbonyl, C1-C6 alkylcarbonyl halide or one of the possible R7 groups; R8 + R9 represent a halide 4 to 6-membered C chain in which one methylene unit can be replaced by oxygen or C1-C4 alkylamino. Also disclosed are the salts of compounds of formula (I). Use as herbicides, for desiccation and defoliation of plants.
