Photocatalytic hydrogen atom transfer and aryl migration strategy for the arylalkylation of activated alkenes with 1-(o-iodoaryl)-alkan-1-ones

A visible-light promoted photocatalysis for remote C(sp3)–H alkylation of 1-(o-iodoaryl)alkan-1-ones with N-(arylsulfonyl)acrylamides via 1,5-hydrogen atom transfer (HAT), 1,4-aryl migration, and SO2-extrusion sequence to achieve various β-alkyl arylalkanones is described. The...
