| 摘 要： | 用SiO2负载壳聚糖（CS），再负载PdCl2，制得催化剂SiO2-CS-PdCl2。研究其对三丁基烃基锡与酰氯偶联反应的催化活性。结果表明，该催化剂对偶联反应具有较高的催化活性和化学选择性，活性基团在反应中不受影响。采用XPS分析对催化剂进行了表征，表明金属Pd为活性中心。考察了催化剂的重复使用性能。

| Abstract: | A silica-supported chitosan-palladium catalyst (SiO_2-CS-PdCl_2) was prepared for coupling reaction of organotins with acyl chlorides. The catalyst exhibited high activity and selectivity for the coupling reaction with active groups unaffected. The catalyst was characterized by XPS and the results showed that the metallic Pd was the active center. Properties of the catalyst for repeated use were investigated. |
