Copper‐Catalyzed CN Bond Formation by CH Functionalization

Abstract

Copper‐catalyzed CN bond formation by CH functionalization has gained increasing attention in recent years, but no review systematically and comprehensively summarizes the references in this field. Herein, we summarized the advances in this field covering literatures from 2008 to 2020, and classified this summary into sp 2 CH functionalization and sp 3 CH functionalization. For each example, the reaction conditions, substrate scope, yield, and if possible, the mechanistic scheme are displayed, and sometimes are compared with similar reactions. At last, the development prospect of this domain is definitely expected to be bright.
