摘要
以苯甲醛或其衍生物对壳聚糖进行接枝改性制得了壳聚糖席夫碱配体,再与Li2PdCl4进行环钯化合成了壳聚糖亚胺环钯化合物催化剂1-10.研究了该类催化剂对碘代苯或碘苯衍生物与丙烯酸偶联反应的催化性能,结果表明该类催化剂具有较好的催化活性和一定的重复使用性能.
Chitosan was modified with Phenyl aldehyde or its derivatives to obtain chitosan-schiff bases, then they were reacted with Li2PdCI4 in methanol to synthesize chitosan-imine-palladacycle complexes 1-10. The performance of catalysts was studied by the reaction of iodobenzene or its derivatives with acrylic acid. The results show that the catalysts have high activity and could be reused some times keeping high yield.
