MCM-41载钯配合物催化性能的研究

Studies of catalytic performance of mesoporous molecular sieve MCM-41 supported Pd complex

以MCM 41分子筛作为固载材料 ,经氨基功能化后与各种钯化合物形成MCM 41载钯配合物 .研究了催化剂的制备条件等因素对催化碘代苯与丙烯酸的Heck芳基化反应性能的影响 .结果表明 ,MCM NH2 载钯配合物具有高的催化活性。

Some new catalysts supported aminopropylsiloxane Pd complex have been prepared. The XRD results indicate that the structure of MCM-41 has been not damaged in the preparation of the catalysts. The catalysts have high activity and stereoselectivity for Heck reaction at 70?℃. In addition, the effect of the preparation condition of catalyst on catalytic performance is also examined.
