sed supported ionic liquid phase (Rh@SILP(Ph3‐P‐NTf2)) enabled the selective hydrogenation and hydrodeoxygenation of aromatic ketones. The flexible molecular approach used to assemble the individual catalyst components (SiO2, ionic liquid, nanoparticles) led to outstanding catalytic properties. In particular, intimate contact between the nanoparticles and the phosphonium ionic liquid is required for
固定在无酸三苯基phosph基支持的离子液相(Rh @ SILP(Ph 3 -P-NTf 2))上的铑纳米颗粒能够选择性氢化和芳族酮加氢脱氧。用于组装各个催化剂组分(SiO 2,离子液体,纳米颗粒)的灵活分子方法导致了出色的催化性能。特别地,纳米颗粒与phospho离子液体之间的紧密接触对于脱氧反应性是必需的。Rh @ SILP(Ph 3 -PNTf 2)催化剂在温和条件下对苄基酮的加氢脱氧具有活性,并且通过调节反应温度以高选择性控制氢化(醇)和加氢脱氧(烷烃)之间非苄基酮的产物分布。多功能的Rh @ SILP(Ph 3 -P-NTf 2)催化剂为Friedel-Crafts酰化产物和木质素衍生的芳族酮的加氢和/或加氢脱氧开辟了生产各种高价值环己烷衍生物的途径。 。
