temperature under atmospheric H2 pressure, and the benzyl protecting groups in the molecules remained intact. Moreover, the recovered Pd/N‐CNF‐H catalyst could be reused without loss of its catalytic activity or chemoselectivity. The Pd/N‐CNF‐H catalyst also acted as an effective hydrogenation catalyst for the reduction of aromatic ketones to the corresponding benzyl alcohol derivatives with good to
支撑在5% -氮掺杂,人字形型碳纳米纤维(钯/ N-CNF-H),这是通过热分解[制备的Pd纳米颗粒的钯2(DBA)3 ⋅三氯甲烷3在甲苯(DBA =苄基丙酮)在N-CNF-H的存在下,被发现是一种高效的催化剂,用于以高周转频率对苄基保护的醇和羧酸衍生物中的烯基和硝基部分进行化学选择性加氢:这些官能团的加氢反应即使在进行过程中也能顺利进行在环境温度和大气压H 2下压力下,分子中的苄基保护基保持完整。此外,回收的Pd / N-CNF-H催化剂可以重复使用,而不会损失其催化活性或化学选择性。Pd / N-CNF-H催化剂还可以作为一种有效的加氢催化剂,用于将芳族酮还原为相应的苯甲醇衍生物,并具有良好或高的产品选择性。
