Copper-Catalyzed Direct Trifluoro- and Perfluoroalkylselenolations of Boronic Acids with a Shelf-Stable Family of Reagents

Herein the copper-catalyzed direct perfluoroalkylselenolation of aryl- and vinylboronic acids is described for the first time. The key to success is the design of new shelf-stable perfluoroalkylselenolating reagents, namely perfluoroalkyl tolueneselenosulfonates. The reaction occurs at room temperature in the presence of commercially available catalyst and ligand in catalytic quantities.
