Reaction of phosphorus monothio acids with oxetanes

Conclusions The reaction of dialkylthiophosphoric and cyclic six and seven-membered thiophosphoric acids with oxetanes gives the S-3-hydroxyalkyl esters of these acids. During synthesis the S-3-hydroxyalkyl esters of the five-membered cyclic thioacids undergo rearrangement to the 3-mercaptoalkyl derivatives.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1128–1130, May, 1981.
