Abstract

An efficient protocol for the direct allylic C(sp3 )-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(sp2 )-C(sp3 ) formation under mild reaction conditions with good functional-group tolerance and excellent regioselectivity.

Keywords: C−H activation; alkenes; allylic compounds; nickel; photocatalysis.
