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’sreagent (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.
Reaction of esters, ortho esters, acetals, thioacetals and epoxides with 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (Lawesson reagent)
