A simple and rapid one-pot protocol is described for the preparation of α- and β-hydroxy sulfides. The direct solvent-free microwaveirradiation of diaryliodoniumsalts, 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.
Abstract A variety of arylsulfides were synthesized by aryl bromides with thiols, with PEG400 and nickel as catalysts under basic conditions in the absence of solvents. This article reported an easy and convenient method for formation of aryl‐sulfur bonds.
