(Bromodimethyl)sulfonium Bromide–Mediated Thiolysis of Epoxides: An Easy Access to β-Hydroxy Sulfides and Benzoxathiepinones in Solvent-Free Conditions

A mild, rapid and highly regioselective opening of epoxides by mercaptans to β-hydroxy sulfides and benzoxathiepinones has been achieved in excellent yields, using catalytic amount of (bromodimethyl)sulfonium bromide in solvent free reaction conditions.
