amines is a useful transformation in organic synthesis, however, it often relies upon stoichiometric reagents or transition-metal catalysis. Herein, a borane-catalysed hydroboration of nitriles to give primary amines is reported. Good yields (48–95%) and chemoselectivity (e.g., ester, nitro, sulfone) were observed. DFT calculations and mechanistic studies support the proposal of a double B–N/B–H transborylation
将腈还原为伯胺是有机合成中一种有用的转化,然而,它通常依赖于化学计量试剂或过渡金属催化。本文报道了硼烷催化的腈的硼氢化反应生成伯胺。观察到良好的产率 (48–95%) 和化学选择性(例如,酯、硝基、砜)。DFT 计算和机理研究支持双B -N/ B - H 转硼酸化机制的提议。
