Dedicated to Professor Paul Knochel on the occasion of his 70th birthday.
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.
