The selective hydrogenation of nitrile groups to primary amines is challenging owing to their high ability to produce secondary and tertiary amines. Herein, we report an efficient system for the hydrogenation of nitrile and nitro groups to primary amines catalyzed by Ni₂P nanoparticles in an aqueous H₃NBH₃ solution under ambient conditions. The system exhibits high catalytic selectivity toward generating primary amines, resulting in good isolated yields. A combination of experiments and theoretical calculations shows that composite interactions among species on the catalyst surface alter the catalytic pathway.

使用Ni2P作为催化剂和氨硼烷在环境条件下将腈和硝基牢固地氢化为伯胺

腈基团选择性地氢化为伯胺具有挑战性，因为它们具有生产仲胺和叔胺的高能力。在本文中，我们报道了在环境条件下，由Ni ₂ P纳米粒子在H ₃ NBH ₃水溶液中将腈和硝基氢化为伯胺的有效体系。该系统对生成伯胺表现出很高的催化选择性，从而获得了良好的分离收率。实验和理论计算的结合表明，催化剂表面上物种之间的复合相互作用改变了催化途径。
