Efficient hydrogenations of nitriles and ketones with molecular hydrogen catalyzed by a well-defined bench-stable bisphosphine Mn(I) complex are described. These reactions are environmentally benign and atomically economic, implementing an inexpensive, earth-abundant nonprecious metal catalyst. A range of aromatic and aliphatic nitriles and ketones were efficiently converted into primary amines and
描述了由定义明确的台式稳定双膦Mn(I)配合物催化的分子氢对腈和酮的有效加氢反应。这些反应在环境上是无害的,并且在原子上是经济的,从而实现了廉价的,富含地球的非贵金属催化剂。一系列芳香族和脂肪族腈和酮分别以良好或优异的收率有效地转化为伯胺和醇。腈的氢化反应在100°C下进行,催化剂负载量为2 mol%和20 mol%的碱(t- BuOK),而酮的氢化反应已经在50°C下进行,催化剂负载量为1 mol%和5摩尔%的碱。在两种情况下,均施加50 bar的氢气压力。
