Iron‐Catalysed Reductive Cross‐Coupling of Alkenes

Radical stuff: Iron‐catalyzed alkene hydrofunctionalization has been reported by a number of groups using the reaction of unactivated alkenes with sodium borohydride or phenylsilane to give alkyl radical intermediates. Reaction with a range of radical traps has been applied to the formation of carbon–carbon and carbon–heteroatom bonds and used recently for reductive cross‐coupling of alkenes.
