Studies on the Synthesis and Perporties of Ethyl-N-Alkylphosphoro(Thioureido)Thioates

Abstract

Abstract O-Ethyl-N-alkylphosphoro(thioureido)thioates(II) were synthesized by the addition of O-ethyl-N-alkylphosphor-isothiocyanatidothioates(I) with corresponding alkyl or aryl amines, in which R=C1, -C3, R1, R2=H, alkyl or aryl. Their structures were confirmed by IR, 1H NMR, MS and elemental analysis. The results of bioassay showed that they had fairly good fungicidal and herbicidal activities. When II(R1=H,R2=i-Pr,Ph,aryl etc.) reacted with chloroacetyl chloride, the compounds III were given.
