Palladium‐Catalyzed Atom‐Transfer Radical Cyclization at Remote Unactivated C(sp³)−H Sites: Hydrogen‐Atom Transfer of Hybrid Vinyl Palladium Radical Intermediates

Abstract

A novel mild, visible-light-induced palladium-catalyzed hydrogen atom translocation/atom-transfer radical cyclization (HAT/ATRC) cascade has been developed. This protocol involves a 1,5-HAT process of previously unknown hybrid vinyl palladium radical intermediates, thus leading to iodomethyl carbo- and heterocyclic structures.
