as dyes, pigments, pharmaceuticals and agrochemicals. The chemoselective catalytic reduction of nitro compounds represents the most important and prevalent process for the manufacture of functionalized anilines. Consequently, the development of selective catalysts for the reduction of nitro compounds in the presence of other reducible groups is a major challenge and is crucial. In this regard, herein
苯胺是合成多种化学品(例如染料,颜料,药物和农用化学品)的重要原料。硝基化合物的化学选择性催化还原代表了功能化苯胺生产的最重要和最普遍的过程。因此,开发在其他可还原基团存在下还原硝基化合物的选择性催化剂是一个重大挑战,也是至关重要的。在这方面,我们在此表明氧化钴(Co 3 O 4由钴-菲咯啉配合物在碳上热解制备的基于-NGr @ C)的纳米材料构成了高度选择性的催化剂,用于使用甲酸作为氢源将硝基芳烃氢化成苯胺。使用这些催化剂,一系列结构多样且功能化的硝基芳烃已被还原为苯胺,具有前所未有的化学选择性,可耐受卤化物,烯烃,醛,酮,酯,酰胺和腈的官能团。
