Nickel-Catalyzed Reductive Cross-Coupling of Chlorobismuths with Aryl Halides

Abstract A straightforward and efficient method for the synthesis of valuable arylbismuthanes via nickel-catalyzed cross-electrophilic coupling of chlorobismuths with aryl halides has been reported. This cross-electrophile C(sp2)–Bi coupling reaction is conducted under mild reaction conditions and exhibits a broad substrate scope. Notably, the described protocol tolerates various sensitive functionalities including alcohol, nitrile, ester, ketone, and aldehyde. Moreover, the application of the generated arylbismuthanes to the Pd-catalyzed cross-coupling reaction is demonstrated.
