Direct Cross‐Coupling of Allylic C(sp3)−H Bonds with Aryl‐ and Vinylbromides by Combined Nickel and Visible‐Light Catalysis

Abstract An efficient protocol for the direct allylic C(sp 3 )−H bond activation of unactivated tri‐ and tetrasubstituted alkenes and their functionalization with aryl‐ and vinylbromides by nickel and visible‐light photocatalysis has been developed. The method allows C(sp 2 )−C(sp 3 ) formation under mild reaction conditions with good functional‐group tolerance and excellent regioselectivity.
