| 摘要 |
The invention relates to previously unknown heterocyclic compounds of the formula <IMAGE> where R1 denotes hydrogen, C1-4-alkyl, C1-4-halogenoalkyl, C2-5- alkenyl or C3-5-alkynyl, R2 denotes halogen or cyano, R3 denotes hydrogen or halogen, R4 denotes hydrogen, halogen or C1-4-alkyl, R5 denotes C1-4-alkyl or, when R1 is different from C1-4- halogenoalkyl, it furthermore also denotes C1-4- halogenoalkyl, and Q denotes one of the groups (a) to (d) (when R1 is different from hydrogen) or a group (c) or (d) (when R1 denotes hydrogen) <IMAGE> where R6 denotes hydrogen or C1-4-alkyl, R7 denotes hydrogen, C1-4-alkyl, phenyl or benzyl, R8 denotes hydrogen or C1-6-alkyl, R9 denotes C1-6-alkyl, C3-6-cycloalkyl or phenyl, or R8 and R9 together denote tri-, tetra-, penta- or hexamethylene, n denotes the number 0 or 1, R10 denotes C1-6-alkyl, C1-6-alkylthio, C2-7- alkoxycarbonyl or C2-7-alkoxycarbonyl-C1-4-alkyl, R11 denotes C1-6-alkyl, trifluoromethyl, C1-6-alkoxy-C1-4- alkyl, C2-7-alkoxycarbonyl-C1-4-alkyl, di(C2-7- alkoxycarbonyl)-C1-4-alkyl, C3-6-cycloalkyl, C1-6-alkoxy, C1-6-alkylthio, C2-7-alkanoyl, C2-7-alkoxycarbonyl, phenyl or 2-furyl, or R10 and R11, together with the carbon atom to which they are bonded, denote a cyclopentane or cyclohexane ring which is optionally substituted by from 1 or 3 C1-4-alkyl groups, R12 denotes C1-8-halogenoalkyl, C3-5-halogenoalkenyl or C3-5-halogenoalkynyl, and R13 denotes hydrogen, C1-8-alkyl, C3-8-alkenyl, C3-8- alkynyl, C2-6-alkoxyalkyl or C3-8-cycloalkyl, phenyl or benzyl which is optionally substituted by from 1 to 3 C1- 4-alkyl groups, and also enol ethers and salts thereof and their preparation, weed-killers which comprise these compounds as active compounds, and the use of the active compounds or weed-killers for controlling weeds.
