Metallaphotoredox-enabled enantioselective aryldifluoromethyl-alkynylation of alkenes via C(sp3)–F bond activation

Enantioselective aryldifluoromethyl-alkynylation of alkenes through C(sp 3 )–F bond activation of ArCF 3 via photoredox/copper catalysis has been reported for the first time. Various products were synthesized with high yields and enantioselectivities.
