In this study, we report a highly selective coupling reaction between triarylbismuthines and isocyanides using palladium diacetate as the catalyst, affording α-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 α-diimines. The coupling reaction exhibits the advantages of high atom economy and convenient operation, with no need for any additive.
在本研究中，我们报道了以二醋酸钯为催化剂，三芳基铋与异腈之间发生的高选择性偶联反应，生成α-二亚胺，并形成三根C-C键。在几种芳基源（Ar-YLn：Y = B、Sn、Pb、Sb、Bi、I）中，只有三芳基铋能成功地与异腈发生偶联，选择性地生成α-二亚胺。该偶联反应具有原子经济性高和操作简便的优点，无需任何添加剂。
