The asymmetric reductive arylation and alkenylation of benzylic chloride under photoredox/nickel dual catalysis using chiral biimidazoline (BiIm) ligand is reported to access 1,1-diaryl alkanes and aryl allylic compounds with good yield as well as stereo- and enantioselectivities. This protocol uses more commercially available and less expensive C(sp2)-Br as the electrophile coupling partner. A primary

photoredox/nickel dual catalysis to access chiral products with good yield and enantioselectivity. The operationally simple reaction was carried out under mild conditions with good functional group tolerance. Due to the use of a stoichiometric equivalent of aryl/alkenylhalides as coupling partners, the sequential and iterative synthesis could be achieved smoothly in one pot for the synthesis of position
