Next, various alkyl radical precursors, including primary, secondary and tertiary radicals, were efficiently engaged in the alkenylation process, resulting in moderate to very good product yields (41-46). The structure of adamantane derivative 44 was confirmed via single crystal XRD. γ-Radicals derived from tetrahydropyran and Boc-protected piperidine, along with αoxy radicals, were successfully engaged under our mild reaction conditions (products 47-49). The optimized protocol tolerated esters, alkynes and alkyl bromides (50-52), with no 'back' radical cyclization of the incipient benzylic radical observed.
