Abstract

A porous magnetic multifunctional copper-based metal-organic framework (MOF) was developed through combined covalent and dative post-synthetic modification (PSM) of the CuBDC. In this regard, a novel magnetic metal-organic framework (MMOF) consisting of supported 1,10-phenanthroline-2,9-dicarbaldehyde (Fe₃O₄@Cu(BDC)-NH₂-PHD) has been fabricated by post-synthetic modifications of Fe₃O₄@Cu(BDC)-NH₂. Subsequently, the prepared nanocomposites were modified using palladium chloride ions (Fe₃O₄@Cu(BDC)-NH₂-PdPHD) to impart catalytic sites. As a result, the fabricated magnetic porous catalyst exhibited great catalytic activity in Suzuki-Miyaura cross-coupling reactions. Some of the essential advantages of the synthesized catalyst are; high catalytic activity, short reaction times, mild conditions, high thermal stability, and reusability. Moreover, his porous magnetic nanomaterial can be used as a new support to immobilize other metals in different catalytic reactions.

钯固定菲罗啉-2,9-二甲醛修饰的磁性 CuBDC MOF 作为可重复使用的异构催化剂用于铃木-宫浦交叉偶联反应

通过对 CuBDC 进行共价和配位合成后修饰（PSM），开发出了一种多孔磁性多功能铜基金属有机框架（MOF）。在这方面，通过对 Fe3O4@Cu(BDC)-NH2 进行合成后修饰，制备出了一种新型磁性金属有机框架（MMOF），该框架由支撑的 1,10-菲罗啉-2,9-二甲醛（Fe3O4@Cu(BDC)-NH2-PHD）组成。随后，使用氯化钯离子（Fe3O4@Cu(BDC)-NH2-PdPHD）对制备的纳米复合材料进行改性，以赋予催化位点。因此，所制备的磁性多孔催化剂在 Suzukii-Miyaura 交叉偶联反应中表现出极高的催化活性。合成的催化剂具有催化活性高、反应时间短、条件温和、热稳定性高和可重复使用等基本优点。此外，这种多孔磁性纳米材料还可作为一种新的载体，在不同的催化反应中固定其他金属。
