摘要

合成了一系列新的MCM-41分子筛固载羧基钯(Ⅱ)配合物

并研究了其催化碘代芳烃与共轭烯烃的Heck偶联反应的性能以及反应温度、溶剂和碱试剂对催化性能的影响。结果表明，MCM-41分子筛固载双羧基钯(Ⅱ)配合物对催化Heck偶联反应具有高的活性、立体选择性和稳定性，在Et3N-DMF或Bu3N-DMF溶剂体系中，在70℃下7 h内可高产率地合成一系列取代的反式偶联产物，其催化性能明显优于无定形SiO2固载的羧基钯(Ⅱ)配合物，而且表面双羧基改性的催化性能也优于单羧基改性的催化剂。

Abstract

A series of new MCM-41 supported carboxyl Pd(Ⅱ) complexes were prepared and their catalytic performance in the Heck arylation of alkenes was studied.The results indicated that the MCM—(COOH)2·Pd(Ⅱ) complex exhibited high catalytic activities

stereo-selectivities and stabilities in the arylation of aryl iodides with styrene

acrylic acid and methyl acrylic at 70℃ in the solvent system of Et3N-DMF or Bu3N-DMF

and was significantly better than SiO2 supported carboxyl Pd(Ⅱ) complex.
