The transition-metal-catalyzed diarylation of isocyanides with triarylbismuthines was investigated in detail, and rhodium catalysts such as [RhCl(nbd)] were found to selectively afford -alkyl diaryl ketimines. On the other hand, palladium-catalyzed diarylation proceeded with the incorporation of two molecules of isocyanide, preferentially yielding ,-dialkyl or ,-diaryl -diimines. In addition, a cascade synthesis of 2,3-diarylquinoxalines starting from the palladium-catalyzed diarylation of isocyanides with triarylbismuthines was successfully achieved.
对过渡金属催化异腈与三芳基铋的二芳基化反应进行了详细研究,发现铑催化剂如[RhCl(nbd)]能选择性地生成α-烷基二芳基酮亚胺。另一方面,钯催化的二芳基化反应伴随着两分子异腈的引入,优先生成α,β-二烷基或α,β-二芳基二亚胺。此外,从钯催化异腈与三芳基铋的二芳基化反应出发,成功实现了2,3-二芳基喹喔啉的串联合成。
