α-arylated amines from simple linear N-sulfonyl amines and aryl boroxines utilizing dual palladium catalysis involving amine dehydrogenation. Bromobenzene serves as a hydride acceptor, and the ensuing imineintermediate undergoes a novel umpolung arylation. Given the wide availability of primaryamines, this method can be expected to be useful for the synthesis of structurally complex amines with varied

A palladium-catalyzed domino N-benzylation/intramolecular directarylation involving sulfonanilides and 2-bromobenzyl bromides has been developed for the first time, providing a workable access to N-sulfonyl dihydrophenanthridines in good to excellent yields. Under the optimized conditions, the formation of 5,6-dihydrophenanthridines was largely controlled over the formation of biaryl sultams containing
