coupling of alkenes and amines holds promise as a perfectly atom-economical approach to amide synthesis, but general methods remain underdeveloped. Herein, we report an alkene hydroaminocarbonylation catalyzed by unmodified, inexpensive cobalt carbonyl under mild conditions and low pressure promoted by light. Silane addition after the reaction enables sequential cobalt-catalyzed amide reduction, constituting
偶联烯烃和胺原料的催化方法在合成化学中很有价值。烯烃和胺的直接羰基偶联有望成为一种完美的原子经济酰胺合成方法,但一般方法仍未开发。在此,我们报道了一种烯烃氢氨基羰基化反应,该反应由未改性、廉价的羰基钴在温和条件下和光促进的低压下催化。反应后添加硅烷可实现钴催化的连续酰胺还原,构成正式的烯烃氢氨基甲基化。这些方法在烯烃和胺组分中都表现出特殊的应用范围,具有高化学选择性和区域选择性,即使在没有溶剂的情况下也能高效进行。通过羰基配体的光解离形成氢钴酸盐被认为是在温和条件下实现催化活性的,这解决了催化中长期存在的挑战。
