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.

Using Se powder as the selenating reagent, the copper-catalyzed double C-Se cross-coupling of aryl iodides, epoxides, and elemental selenium has been developed. This strategy provides a straightforward approach to the synthesis of β-hydroxy phenylselenides with excellent regioselectivity of the ring opening reaction. This process proceeds in generally good yields and is compatible with a broad range of functional groups.

The ring opening reaction of a wide range of mono-, di- and trisubstituted epoxides with the phenylselenide anion under PTC conditions provides a simple, mild and efficient method for preparation of β-hydroxy phenylselenides with high regio- and stereoselectivity in yields from 67 to 98%. The reactions are carried out in aqueous NaOH/ THF using aminoiminomethanesulfinic acid (thiourea dioxide, TDO) to generate sodium phenylselenide from diphenyldiselenide.
