Abstract

A novel and efficient method has been developed for the synthesis of N,N-dialkylamino-O-alkyl-2-(1-methyl-2-oxopropylidene)phosphorohydrazido oximes 5. The reactions involve the condensation of diacetylmonoxime and N,N-dialkylamino-O- alkylphosphorohydrazides in the presence of activated silica and give the corresponding target oximes in excellent yields under mild conditions.
Keywords: Hydrazides; diacetylmonoxime; marine fish toxin; phosphorohydrazido Hydrazides; diacetylmonoxime; marine fish toxin; phosphorohydrazido oximes. Hydrazides; diacetylmonoxime; marine fish toxin; phosphorohydrazido Hydrazides; diacetylmonoxime; marine fish toxin; phosphorohydrazido oximes.
