Abstract: A palladium-catalyzed α-arylation reaction of unactivated sulfones with aryl chlorides is presented. High reactivity and chemoselectivity was achieved with a combination of Buchwald's 2nd generation palladium precatalyst and Kwong's indole-based phosphine ligand. A variety of aryl… read more here.
