Copper‐Catalyzed CH Functionalization Involving Radicals

Abstract Copper salts have been regarded as powerful catalysts for radical CH functionalization in organic synthesis. This article summarizes recent advances in copper‐catalyzed CH functionalization via radical pathways, with particular emphasis on CC, CN, CO, CSi, CP, CS, and C–halogen bond formation. These CH functionalization methodologies aim toward a broad readership that includes chemists in academia and those active in the industrial community.
