Photochemically Driven Nickel‐Catalyzed Carboxylative C−N Coupling: Scope and Mechanism**

Abstract

AbstractHerein we disclosed an unprecedented photochemically driven nickel‐catalyzed carboxylative Buchwald–Hartwig amination to access a wide range of aryl carbamate derivatives. This reaction is performed under mild condition of temperature and atmospheric pressure of CO2 starting from commercially available (hetero)aryl iodides/bromides derivatives and alkyl amines preventing the formation of hazardous and/or toxic waste. Moreover, preliminary mechanistic investigations including stochiometric experiments as well as DFT calculations allow us to shed light on the reaction mechanism.
