dissociation energy. Here we report a divergent radical transformation of a rich library of structurally diverse gem-dichloroalkanes by the controllable dechloroalkylation of alkenes by excited-state dinuclear gold catalysis. The gem-dichloroalkanes can be used to assemble C(sp3)–C(sp3) bonds as a chloroalkyl radical, an alkyl radical cation and a carbeneequivalent precursor for carbon-chain propagation
