标题：silver-catalyzed one-pot three-component selective synthesis of β-hydroxy selenides
abstract: 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 silvercatalyzed radical selenation of the arylboronic acids to generate a diselenide, and subsequent selenium-mediated selective ring-opening arylselenation of epoxides.
