Herein 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.
Keywords: Buchwald-Hartwig; carboxylation; density functional theory; dual catalysis; photochemistry.
