摘要：
A cobalt-catalyzed regioselective C-3 alkylation of coumarins was realized under mild reaction conditions, during which a variety of substituted coumarins including those containing sensitive functional groups could smoothly undergo the selective C(sp(2))-C(sp(3)) bond formation with a series of cyclic or straight-chain alkyl ethers.
