amide-directed 1,2-diarylation, which involves carbonyl coordination. The synthetic utility of the method arises from the dual function of the sulfonamide as both a directing group and a masked amine nucleophile. This is highlighted by various product diversifications where complex amine compounds are synthesized in a two-step sequence of N-functionalization and deprotection of the sulfonyl group.
