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.

Ultrasound assisted ring-opening of epoxides with 1,2-diphenyldiselenide in PEG-400/H2O in the presence of sodium dithionite has been developed, affording β-hydroxy selenides with high regioselectivity in good to excellent yields. Importantly,
Regioselective ring-opening reactions of 1,2-epoxides with thiols and arylselenols directly promoted by [Bmim]BF4
