Carbamates and sulfonamides serve as directing groups in Ni-catalyzed asymmetric Suzuki reactions for cross-coupling of unactivated alkyl electrophiles. Racemic secondary bromides and chlorides undergo C-C bond formation in a stereoconvergent process in good ee at room temperature in the presence of a commercially available Ni complex and chiral ligand.
