| 摘 要： | 用SiO2负载天然生物高分子材料壳聚糖（简写为CS），再与PbCl2配位，制得催化剂SiO2-CS-PdCl2，利用Pd-Ni双金属协同效应和高分载体对催化活性物种的保护，使催化剂在苯乙烯及其衍及生物的氢酯基化反应中表现出了较高的催化活性和选择性。并重点考察了反应条件、不同底物以及其它载体对反应的影响。

| Abstract: | Silica supported chitosan palladium complex SiO\-2 CS PdCl\-2 has good conversion and regioselectivity in the hydroesterification of styrene. The high activity and selectivity of the catalyst are achieved by the synergic effect of Pd Ni bimetallic system and the effect of polymer protection. Effects of reaction parameters were studied to achieve optimum reaction conditions. The hydroesterification of styrene derivatives is also investigated. |
