THE CHEMISTRY OF α, ω-MERCAPTOALCOHOLS IN THE PRESENCE OF DIETHOXYTRIPHENYLPHOSPHORANE. TEMPERATURE DEPENDENCE OF CYCLODEHYDRATIONS AND S-ETHYLATIONS

Abstract
Diethoxytriphenylphosphorane (DTPP) is easily prepared by oxidative addition of triphenylphosphine with diethyl peroxide. DTPP converts a variety of mercaptoalcohols to cyclic sulfides as well as hydroxythioethers. The temperature dependence (+25 → −25°C) of the product distribution has synthetic potential.
