A straightforward and practical palladium-catalyzed regioselective arylation of anilides is described. This method provides a new approach to prepare 2-aminobiaryls, which are valuable precursors for the synthesis of various N-containing heterocycles, using arylsulfonyl chlorides as readily available arylating agents.

An unprecedented remote amide-directed palladium-catalyzedintermolecularhighly selective benzylic C-H amination with N-fluorobenzenesulfonimide is developed, which represents the first direct benzylic C-H amination with a non-nitrene nitrogen source. This methodology provides a novel approach to circumvent the common ortho aromatic C-H selectivity in directed palladium catalyzed C-H functionalization
AbstractAn efficient o‐arylation of pivalamides by aryl iodides via rhodium(III)‐catalyzed C–H activation is demonstrated for the first time. Further, the biaryl products can be converted effectively into biologically active phenanthridine and phenanthridinone derivative.magnified image
