Abstract
O-Aryl O-(1,2,2,2-tetrachoroethyl)phos- phoramidothioates 3a–h and their thiophosphoric hydrazides 4a–e were synthesized by reactions of O-aryl O-(1,2,2,2-tetrachoroethyl)thiophosphorochloridates 2 with amines and hydrazines, respectively. Their structures were characterized by elemental analysis IR 1H NMR, 31P NMR, and MS. The O-aryl O-(1,2,2,2-tetrachloroethyl)thiophosphoric hydrazides 4a–d (R2=H) can be transformed into 1,3,4,2-oxadiazaphospholanes 5a–d by the reaction of triethylamine. The results of preliminary bioassays indicated that some of the title compounds have good insecticidal activities against nematodes (Meloidogyne spp.) and pea aphids. © 1999 John Wiley & Sons, Inc.
