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