Cobalt-catalyzed C–H activation: recent progress in heterocyclic chemistry

Abstract

Cobalt-catalyzed C–H activation has gone through some major advancements in the past couple of decades. These reactions have proven to be highly efficient, selective, and atom-economical transformations without the requirement for pre-functionalization. These methodologies have found wide applications in heterocyclic chemistry for the synthesis and functionalization of heterocycles. This review focuses on the recent contributions made by cobalt-catalyzed C–H activation protocols toward heterocyclic chemistry from 2016 to 2018.
