Abstract
Abstract IN WHICH X is oxygen or sulphur, R3 is hydrogen, alkyl or alkenyl, R4 is alkyl or cycloalkyl, and R1 and R2 are each lower alkyl or alkenyl, R1 is lower alkyl and R2 is alkoxyalkyl or haloalkyl, or R1 and R2 together with the nitrogen atom to which they are attached, form a heterocyclic ring and possess insecticidal and acaridicidal activity. The compounds have the formula
