Abstract 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. the past decade, earth‐abundant Cp*Co(III)‐catalysts promising alternative to expensive transition metals, providing unique selectivity and reactivity. Minireview, we summarized important progresses area of Cp*Co(III)‐catalyzed until 2017.

Weinreb Amide Directed Versatile C−H Bond Functionalization under (η⁵‐Pentamethylcyclopentadienyl)cobalt(III) Catalysis

Chemistry - A European Journal, Год журнала: 2018, Номер 24(40), С. 10231 - 10237

Опубликована: Май 7, 2018

The (η5 -pentamethylcyclopentadienyl)cobalt(III) (Cp*CoIII )-catalyzed C-H bond functionalization of aromatic, heteroaromatic, and α,β-unsaturated Weinreb amides was explored. allylation reactions with the use allyl carbonate a perfluoroalkene, oxidative alkenylation ethyl acrylate, iodination N-iodosuccinimide, amidation dioxazolones were catalyzed by Cp*Co(CO)I2 in presence cationic Ag salt AgOAc to afford various synthetically useful building blocks. Mechanistic studies disclosed that activation step rate determining virtually irreversible.
