Metal-Catalyzed Decarboxylative C-H Functionalization

Abstract

C-H bond activation and decarboxylation are two significant processes in organic synthesis. The combination of these processes provides a novel synthetic strategy, that is, decarboxylative C-H bond functionalization. Considerable attention has been focused on such an active research field. This review offers an overview of the utility of decarboxylative C-H bond functionalization in the synthesis of various organic compounds, such as styrenes, chalcones, biaryls, and heterocycles, covering most of the recent advances of the decarboxylative functionalization of Csp-H, Csp²-H, and Csp³-H bonds, as well as their scopes, limitations, practical applications, and synthetic potentials.
