✦ Synopsis

a b s t r a c t

Regioselective ring-opening reactions of 1,2-epoxides with ArSH and ArSeH promoted by ionic liquid [Bmim]BF 4 were investigated. A variety of b-hydroxy selenides and b-hydroxy sulfides were obtained in excellent yields (81-99%) with good regioselectivities using a mild, simple and environmentally benign procedure.
