Certain bicyclic 2-iminothiazolidine oximes, which are useful as intermediates for the preparation of insecticidal compounds and compositions, have the general formula:- <CHEM> wherein R1 and R2 are the same or different and are individually hydrogen, C1-C6 alkyl or halogen; n = 0, 1 or 2; X = -N-OH including E&Z isomers; and A is an acyclic, cyclic, or bicyclic alkylene or alkenylene group, or an ortho-substituted phenylene group which forms an unsaturated five, six or seven membered heterocyclic ring which can also contain oxygen, sulfur, nitrogen, or carbonyl in addition to the two nitrogens, said alkylene, alkenylene, or phenylene ring systems being optionally substituted with one or more C1-C4 alkyl, cyclohexyl alkoxy, phenoxy, alkylthio, halogen, amido, alkylamido, nitrile, acyl, or nitro groups. |
