Palladium-catalyzed α-arylation/β-elimination of sulfones†
Abstract
Here, we disclose a palladium-catalyzed cross-coupling reaction of benzylic sulfones with aryl triflates for the synthesis of 1,1-diarylethylenes. This palladium-catalyzed transformation tolerates various benzylic sulfones, especially heteroaromatic-substituted sulfones, with good to excellent yields.
