โœฆ Synopsis

Synthesis and Insecticidal Activity of O-Aryl O-(1,2,2,2-Tetrachloroethyl)phosphoramidothioates and Their Thiophosphoric Hydrazides.

-The title O-aryl-phosphoramidothioates (V) and their thiophosphoric hydrazides (VI) are synthesized by reactions of O-aryl-Otetrachloroethylthiophosphorochloridates (III) with amines and hydrazine, respectively. Products (VI) can be easily transformed into oxadiazaphospholanes (VII). Some of the compounds (V) and (VI) show good insecticidal activity against nematodes and pea aphids.
