摘要
A cobalt-N -heterocyclic carbene catalytic system promotes pyridine-directed olefinic C-H alkylation reactions using a variety of primary and secondary alkyl chlorides under mild conditions. Radical clock experiments suggest that the reaction involves single-electron transfer from the cobalt intermediate to the alkyl chloride
