enantioconvergent C(sp3)–C(sp3) bondformations have been made with nickel-catalyzed cross-coupling of racemic alkyl electrophiles with organometallic reagents or nickel-hydride-catalyzed hydrocarbonation of alkenes. Herein, we report an unprecedented enantioselective C(sp3)–C(sp3) reductive cross-coupling by the direct utilization of two different alkyl halides with dual nickel/photoredoxcatalysis system.
