摘要

摘要利用XRD、TEM、BET、FT-IR、TGA和VSM等技术，制备了一种固定在MCM-41介孔通道上的氨基乙基丙烯酰胺树枝状配体钯配合物。所制备的纳米结构材料被发现是芳基卤化物和乙烯基C–H的Heck反应的磁性可回收催化剂。该催化剂很容易用外部磁铁回收，并可根据钯的负载量以不同的浸出量重复使用。还进行了热过滤测试，证明非均质样品中的钯可以溶解，然后再沉积在载体材料表面。图形摘要

Magnetically recoverable nanostructured Pd complex of dendrimeric type ligand on the MCM-41: Preparation, characterization and catalytic activity in the Heck reaction

Abstract A palladium complex of a dendrimer type ligand of aminoethylacrylamide immobilized onto the mesoporous channels of MCM-41 with magnetic core was prepared and characterized using various techniques such as XRD, TEM, BET, FT-IR, TGA, and VSM. The prepared nanostructured material was found as a magnetically recoverable catalyst for Heck reaction of aryl halides and vinylic C–H. The catalyst is easily recoverable with an external magnet and is reusable with different leaching amounts depending to loading of Pd. A hot filtration test was also performed and gave evidence that Palladium in heterogeneous samples can dissolve and then redeposit on the surface of the support material. Graphical Abstract
