The selective hydrogenation of nitroarenes is a key transformation for the production of aromatic amines, which are primary intermediates in the synthesis of pharmaceuticals, agrochemicals, and dyes. However, most reaction processes require toxic organic solvents and suffer from poor selectivity in the presence of other reducible groups. Herein, we report a successful example of nanoclusters of ultrafine
硝基芳烃的选择性加氢是生产芳族胺的关键转变,芳族胺是药物,农药和染料合成中的主要中间体。然而,大多数反应过程需要有毒的有机溶剂,并且在存在其他可还原基团的情况下选择性差。在这里,我们报告了一个成功的例子,它是通过一种简便的两步浸渍方法,用1,10-菲咯啉水溶液制备的,在N改性有序介孔CMK-3碳(Pd / N-CMK-3)上负载的超细Pd纳米簇和H 2 PdCl 4在不存在溶剂的情况下,用氢高效地将各种硝基芳烃氢化,并选择性地将其氢化为相应的芳族胺。Pd / N-CMK-3催化剂可轻松回收用于多种循环反应,而不会损失催化性能。
