Cobalt-Catalyzed, Chelation-Assisted C-H Bond Functionalization

While chelation-assisted C-H bond activation by a transition-metal complex serves as a versatile platform for the development of regioselective C-H bond-functionalization reactions, the capability of first-row transition metals to catalyze such transformations has scarcely been explored. This highlight article illustrates how cobalt has recently emerged as a promising metal for chelation-assisted C-H bond functionalization.
