A convenient, multi-component reaction of organoboronic acids, selenium powder and epoxides has been developed, providing an efficient protocol for the synthesis of β-hydroxy selenides with excellent selectivity and good functional group tolerance. Preliminary mechanistic studies suggest that the reaction proceeds through the silver-catalyzed radical selenation of the arylboronic acids to generate a diselenide, and subsequent selenium-mediated selective ring-opening arylselenation of epoxides.

Regioselective ring-opening reactions of 1,2-epoxides with ArSH and ArSeH promoted by ionic liquid [Bmim]BF4 were investigated. A variety of β-hydroxy selenides and β-hydroxy sulfides were obtained in excellent yields (81-99%) with good regiose
