The direct C–H activation of inert C(sp3)–H bonds in a hydrocarbon chain is an attractive target in organic synthesis but C-H activation driven by vinyl carbocations remains underdeveloped. Here, the authors design a double C(sp3)–H functionalization of unactivated alkyl CH2 groups to produce substituted quaternary carbon stereocenter via insertion of vinyl carbocations.
