A cascade alkylarylation reaction of 2-isocyanobiphenyls with simple alkanes for 6-alkyl phenanthridines has been developed through dual C(sp3)âH/C(sp2)âH functionalizations. The synthetic method has the advantages of high yields, good compatibility of functional groups and mild reaction conditions, although very unreactive alkanes were involved in the reaction. A plausible mechanism through both copper-catalyzed and DTBP mediated pathways has also been proposed.
