摘要
Compounds of the formulae I and II IMAGE (I) IMAGE (II) wherein R1, R2 and R3 independently of one another are each hydrogen, C1-C4-alkyl, methoxy, halogen, trifluoromethyl or nitro, R4 is hydrogen or methyl, R5 is C1-C3-alkyl, R6 is C1-C6-alkyl, C2-C6-alkenyl, C3-C5-alkynyl, C3-C6-cycloalkyl, C2-C4-(alkoxyalkyl) or C2-C4-(alkylthioalkyl), and R7 is C1-C12-alkyl, C3-C5-alkenyl or C3-C8-cycloalkyl, and the acid addition salts of compounds of the formula I, are novel. The compounds of the formula II can be used as starting materials for producing compounds of the formula I. The mentioned compounds of the formulae I and II have a pesticidal action, especially an acaricidal and insecticidal action, and are particularly effective against plant pests.
