Abstract: Visible⁃light⁃photoredox catalysis has been recognized as a powerful technique to facilitate activation of organic molecules,enabling achievement of a wide variety of new chemical reactions.The combination of photoredox catalysis and nickel catalysis has shown even greater potential in promoting the cross⁃coupling reactions,owing to the advantages of low energy barrier,mild reaction condition and high selectivity.This review mainly focuses on the progress of carbon⁃carbon and carbon⁃heteroatom bond formation via the combination of photoredox catalysis and nickel catalysis in recently.The mechanisms of visible⁃light⁃photoredox catalyzed C-X (X＝C,N,O,P,S) bond formation are discussed in details.

Key words: Visible?light?photoredox catalysis, Nickel catalysis, Coupling reaction, Carbon-carbon bond, Carbon?heteroatom bond
