1,2-arylmethylation cascades of N-(arylsulfonyl)acrylamides for the assembly of 2,2-disubstituted-N-arylbutanamides containing an all-carbonquaternarycenter is presented. This reaction enables the one-step formation of two new C–C bonds through a sequence of methylation/1,4-aryl migration/desulfonylation using an organic peroxide as the methyl resource with a broad substrate scope and excellent functional
