Abstract

A simple and rapid one-pot protocol is described for the preparation of α- and β-hydroxy sulfides. The direct solvent-free microwave irradiation of diaryliodonium salts, potassium thiocyanate, and ethylene glycol/β-propylene glycol without any catalyst or base affords the final compounds in good yields (65–95 %) in around 10–25 min.
