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.

Abstract: Reactions of secondary thioamides with diaryliodonium salts under basic, transition metal-free conditions resulted in chemoselective S-arylation to provide aryl thioimidates in good to excellent yields. Equimolar amounts of thioamide, base and diaryliodonium salt were sufficient… read more here.
