title: Metal-Free Mediated Meerwein-Type Reaction: A Radical Cascade Arylation/Aryl Migration/Desulfonylation of Conjugated Alkenes.
abstract: A metal-free cascade arylation/aryl migration/desulfonylation of N-phenyl-N-(phenylsulfonyl)methacrylamide is described. The in situ generated diazonium salts from anilines and t-BuONO are used as aryl precursors. This process provides an efficient strategy for the synthesis of α-all-carbon quaternary stereocenters amides. A radical mechanism was proposed for this transformation.
