在此,我们公开了通过镍催化的不饱和肟酯与容易获得的芳基卤化物的还原交叉偶联对烯烃进行一般且实用的亚氨基化,为构建吡咯啉衍生物提供了一种权宜之计。不存在有机金属试剂使反应能够在温和的条件下发生,具有广泛的底物范围和良好的官能团耐受性。此外,其他基于 C 的亲电子试剂,包括烯基、炔基和烷基卤化物或假卤化物,也是该反应的合适底物。

Imidoyl (PhN=CR.) or acyl (RCO.) radicals undergo electron transfer to alkylmercury halides in Me2SO or PhH solution. Addition of t-Bu-. or i-Pr-. to isonitriles followed by electron transfer forms the nitrilium ion which is converted into the amide in Me2SO; into the imidoyl halide in PhH, and into the amidine in PhH solution containing primary or secondary amines.
