Abstract High‐valent (pentamethylcyclopentadienyl) cobalt (III)[Cp* Co (III)] catalysts were
found as inexpensive alternatives to (pentamethylcyclopentadienyl) rhodium (III)[Cp* Rh (III)] …

An environmentally friendly electrochemical protocol about cobalt-catalyzed C–H amination
of arenes has been developed, which offers a simple way to access synthetically useful …

This review focuses on cobalt-catalyzed, chelation-assisted Csingle bondH functionalization
reactions in which an N, N′-bidentate directing group is used. Cobalt complexes are now …

Over the last decade, high-valent cobalt catalysis has earned a place in the spotlight as a
valuable tool for C–H activation and functionalization. Since the discovery of its unique …

Herein we report a cobalt-catalyzed enantioselective C–H/N–H annulation of aryl
sulfonamides with allenes and alkynes, using either chemical or electrochemical oxidation …

Versatile cobalt catalysis enabled electrochemical C–H activation with allenes. Thus, allene
annulations were accomplished in terms of C–H/N–H functionalizations with excellent levels …

Considerable research attention has been directed towards the use of first‐row transition
metals in organic synthesis. The more abundant, and less expensive cobalt is considered to …
