In this study, we report a highly selective coupling reaction between triarylbismuthines and isocyanides using palladium diacetate as the catalyst, affording 伪-diimines, with the formation of three C鈥揅 bonds. Among several aryl sources (Ar鈥揧Ln: Y = B, Sn, Pb, Sb, Bi, I), only triarylbismuthines successfully undergo coupling with isocyanides to selectively afford 伪-diimines. The coupling reaction exhibits the advantages of high atom economy and convenient operation, with no need for any additive.
