Abstract

Compounds of the formula I and II ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 independently of one another are each hydrogen, C.sub.1 -C.sub.4 -alkyl, methoxy, halogen, trifluoromethyl or nitro, R.sub.4 is hydrogen or methyl, R.sub.5 is C.sub.1 -C.sub.3 -alkyl, R.sub.6 is C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -aklenyl, C.sub.3 -C.sub.5 -alkynyl, C.sub.3 -C.sub.6 -cycloalkyl, C.sub.2 -C.sub.4 -(alkoxyalkyl) or C.sub.2 -C.sub.4 -(alkylthioalkyl), and R.sub.7 is C.sub.1 -C.sub.12 -alkyl, C.sub.3 -C.sub.5 -alkenyl or C.sub.3 -C.sub.8 -cycloalkyl, and the acid addition salts of compounds of the formulae 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 pest
