The cobalt(III)-catalyzed chelation-assisted allylation of arene C–H bonds was accomplished by employing allyl carbonates. The important features of the present reaction include the use of directing groups such as pyrazoles and pyridines, wide functional-group tolerance, and the synthesis of various allylated (hetero)arenes in good to excellent yields. On the basis of the observations, a plausible mechanism is also proposed involving the formation of a π-allyl species. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

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. © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

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

An efficient cobalt(III)-catalyzed intramolecular cross-dehydrogenative C−H/N−H coupling of ortho-alkenylanilines has been developed utilizing O2as a terminal oxidant. The developed reaction tolerates various reactive functional groups and allows the synthesis of diverse indole derivatives in good to excellent yields. The method was successfully extended to the synthesis of benzofurans through the intramolecular cross-dehydrogenative C−H/O−H coupling of ortho-alkenylphenols. © 2016 Wiley-VCH Verlag GmbH & Co.
