摘　　要：用不同方法制备了壳聚糖钯配位络合物,并用 FTIR、XPS、XRD 和 DTA-TG 对其进行了表征。结果表明壳聚糖与钯发生配位作用形成了壳聚糖钯配位络合物。研究了该络合物对碘代苯与丙烯酸进行交叉偶联烷基化反应的催化性能,结果表明其具有良好的催化活性。Chitosan-immobilized palladium complex was prepared by different methods, and its structure was characterized by FTIR, XPS, XRD and DTA-TG. The results showed that chitosan had coordinated with palladium. In addition, the study on its catalytic performance for Heck arylation of acrylic acid with iodobenzene showed that the catalyst had high activity and regioselectivity for the synthesis of cinnamic acid.
