Abstract

Previously, It has been reported that the reaction of L.R. with Di and Tri alkyl phosphites afforded the thioproducts. Here in, we have reacted Lawesson’s reagent (L.R.,1) with triethylphosphite 2 in refluxing acetonitrile to give three phosphonate derivatives 3, 4 and 5 respectively. Structures of the later products were confirmed by analytical and spectroscopic evidences.
