novel catalytic enantioselective protocol generating chiral trifluoromethylated alkynes with high yields and selectivities has been established. It uses a cooperative photoredox and nickel catalysis system, and expands the nickel-catalysed asymmetric reductive cross-coupling of organohalides from the traditional single-electron transfer to halogen-atom transfer.
