Here, we prepared an efficient and reusable catalyst by stepwise post-synthetic modification of surface nitrogen-enriched Cu(BDCNH2) metal-organic frameworks (MOFs) and used it as a catalyst for the preparation of [Cu(BDCNH2) -AuNTf2]. Catalytic performance results of the [Cu(BDCNH2)-AuNTf2] catalyst showed high efficiency in modulating the microenvironment of AuNTf2 Nanoparticles. Successful preparation
在这里,我们通过对表面富氮的Cu(BDC NH 2 )金属有机骨架(MOF)进行逐步后合成修饰,制备了一种高效且可重复使用的催化剂,并将其用作制备[Cu(BDC NH 2 ) -AuNTf 2 ]。[Cu(BDC NH 2 )-AuNTf 2 ]催化剂的催化性能结果显示出对AuNTf 2纳米颗粒微环境的高效调节。[Cu(BDC NH 2 )-AuNTf 2 ]催化剂的成功制备已通过多种技术证明,包括FT-IR、XRD、SEM、BET、EDS、ICP和TGA。烯丙氨基E的合成在AuNTf 2纳米颗粒催化存在下,在温和条件下进行了具有良好产率和高立体选择性的β-烯酰胺的合成。清洁方法、催化剂制造容易、效率高和可回收性是该过程最重要的优点。
