dehydrogenation and nitroarenes hydrogenation has been reported as a novel strategy for the preparation of aromatic amines. However, the practical application of this strategy is subjected to the high‐cost and tedious preparation of supported noble metal nanocatalysts. The commercially available CuO powder is herein demonstrated to be a robust catalyst for hydrogenation of nitroarenes using ammonia borane
串联氨硼烷脱氢和硝基芳烃氢化已被报道为制备芳族胺的新策略。然而,该策略的实际应用受到昂贵且繁琐的负载型贵金属纳米催化剂的制备的影响。本文证明可商购获得的CuO粉末是在温和条件下使用氨硼烷作为氢源用于硝基芳烃加氢的强力催化剂。通过这种方法可以获得许多胺(甚至是位阻,卤代和二胺)。这种单金属催化剂的特点是无载体,出色的化学选择性,低成本和高可回收性,这将有利于其在制备还原化学中的未来应用。
