One-Pot Tandem Photoredox And Cross-Coupling Catalysis With A Single Palladium Carbodicarbene Complex

The combination of conventional transition-metal-catalyzed coupling (2 e− process) and photoredox catalysis (1 e− process) has emerged as a powerful approach to catalyze difficult cross-coupling reactions under mild reaction conditions. Reported is a palladium carbodicarbene (CDC) complex that mediates both a Suzuki–Miyaura coupling and photoredox catalysis for C−N bond formation upon visible-light irradiation. These two catalytic pathways can be combined to promote both conventional transition-metal-catalyzed coupling and photoredox catalysis to mediate C−H arylation under ambient conditions with a single catalyst in an efficient one-pot process
