在本研究中，我们报道了一种高选择性的偶联反应，三芳基铋和异腈使用二乙酸钯作为催化剂，提供α-二亚胺，形成三个C-C键。在几种芳基源（Ar-YLn：Y = B、Sn、Pb、Sb、Bi、I）中，仅三芳基铋成功地与异氰化物偶联以选择性地提供α-二亚胺。该偶联反应具有原子经济性高、操作简便、不需要任何添加剂等优点。
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.
