The first enantioselective alkynylation of benzylic C-H bonds via copper-catalyzed radical relay has been established herein, which provides an easy access to structurally diverse benzylic alkynes in good yields with excellent enantioselectivities. A key step for the asymmetriccopper-catalyzed radical relay process is the enantioselective capture of a benzylic radical with chiral (Box)CuII-alkynyl
