Palladium-catalyzed desulfitative cross-coupling of arylsulfinates with arylboronic acids

Abstract

Palladium (Pd)-catalyzed desulfitative cross-coupling reactions of sodium arylsulfinates with a wide variety of arylboronic acids were achieved in good to excellent yields under simple aerobic conditions. These catalytic reactions could be accelerated by addition of a catalytic amount of Cu(II) salts as co-catalyst. Moreover, these reactions were tolerant to all of the tested functional groups, making them attractive alternatives to the traditional cross-coupling reactions.
