Developments in Cp*Co III ‐Catalyzed C−H Bond Functionalizations

Transition‐metal‐catalyzed C−H bond functionalization has emerged as a powerful tool in contemporary organic synthesis. In this aspect, precious metal‐based high‐valent catalysts have been extensively studied. In the past decade, earth‐abundant high‐valent Cp*Co(III)‐catalysts have emerged as a promising alternative to the expensive transition metals, providing unique selectivity and reactivity. In this Minireview, we summarized important progresses in the area of Cp*Co(III)‐catalyzed C−H bond functionalization until 2017.
