in catalysis, while their synergistic catalysis in the one-pot reaction is still a largely untapped area, and reports are very limited. Herein, Pd NPs were loaded on a zeolite-type MOF (MIL-101(Cr)-NH2) via post-synthetic impregnation approach to form composites Pd@MIL-101(Cr)-NH2. In addition, the obtained dual-functional Pd@MIL-101(Cr)-NH2 showed great catalytic performance (>99% yields) in the one-pot
金属有机骨架(MOFs)包裹的金属纳米粒子(NPs)在催化方面具有巨大的潜力,而它们在一锅反应中的协同催化仍然是一个很大程度上未开发的领域,并且报道非常有限。在此,Pd NPs通过合成后浸渍方法负载在沸石型 MOF (MIL-101(Cr)-NH 2 ) 上以形成复合材料 Pd@MIL-101(Cr)-NH 2。此外,获得的双功能Pd@MIL-101(Cr)-NH 2在一锅 Sonogashira-Knoevenagel 和 Heck-Knoevenagel 反应中显示出很好的催化性能(>99% 的产率)。此外,所有表征方法表明,Pd-Brønsted 碱催化剂具有高稳定性,避免金属团聚、浸出,并且在相同情况下经过 6 次循环后仍保持高活性。这些反应对于生产具有较高经济效益的苄基丙二腈衍生物具有潜在意义。
