摘　　要：以胶原蛋白为载体制得了生物高分子负载钯催化剂,利用XPS、XRD等手段对其进行了结构表征.研究了该催化剂对碘代苯与丙烯酸交叉偶联生成反式-肉桂酸的催化性能.考察了不同反应因素(溶剂、温度、原料比、缚酸剂及其用量、催化剂用量、反应时间)对反应的影响,确定了该催化剂对碘代苯与丙烯酸交叉偶联生成反式-肉桂酸的适宜反应条件.Collagen supported palladium catalyst was prepared with a simple method and characterized by means of XPS and XRD techniques. The performance of this catalyst for the cross-coupling reaction of iodobenzene with acrylic acid was studied. The Effect of different reaction conditions （solvent, reaction temperature, molar ratio of iodobenzene and acrylic acid, kind and amount of base, amount of catalyst, reaction time） on the yield was investigated. The suitable condition of the reaction was obtained.
