An existing challenge is the development of efficient regioselective catalytic systems that are compatible with stable hydroboration reagents and can be rendered enantioselective by the use of nonracemic ligands. Copper(I) complexes with chelating phosphines catalyzed the regio‐ and enantioselective hydroboration of styrenes with pinacolborane (PinBH) at room temperature to afford the corresponding
