摘　　要：首先胺功能化修饰介孔材料MCM-41,再与二-(吡啶-2-基-)甲酮缩合成席夫碱,最后通过Pd(OAc)2配位制备了MCM-41负载双齿氮钯配合物,采用X射线衍射(XRD)以及X射线光电子能谱(XPS)对其结构表征.该负载催化剂在以二甲苯为溶剂,K2CO3为碱以及n-Bu4NF用作添加剂的Suzuki偶联中表现出优越的催化性能.The mesoporous materials of MCM-41 was amine functional modified firstly, followed by condensation with di（pyridin-2-yl）methanone to form the schiff base. Finally, the MCM-41 supported bidentate nitrogen palla- dium complexe was synthesized. The structure of the supported catalyst was characterized by X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. Using xylene as a solvent, K2CO3 as base and n-Bu4NF as an additive, the supported catalysts exhibited superior catalytic properties on Suzuki coupling.
