coordination. The magnetization of modified chitosan was done using of Fe3O4 nanoparticles. In the presence of coordinated groups of glycocyamine containing amidino and carboxylate, copper ions were immobilized on this magnetic biopolymer. This new nanocomposite (Fe3O4@CSC@AG@Cu) was characterized by FT-IR, FE-SEM, EDX, XRD, VSM, DRS and ICP analysis. After which, its catalytic activity was examined in the three
摘要Trichloro-1,3,5-triazine试剂用于壳聚糖功能化,并作为功能化壳聚糖和糖胺之间的桥梁,形成铜配位的生物配体。改性壳聚糖的磁化是使用Fe3O4纳米粒子完成的。在含有glyco基和羧酸根的糖胺的配位基团的存在下,铜离子被固定在该磁性生物聚合物上。通过FT-IR,FE-SEM,EDX,XRD,VSM,DRS和ICP分析对这种新型纳米复合材料(Fe3O4 @ CSC @ AG @ Cu)进行了表征。此后,在脂族和芳族醛,仲环胺和苯基乙炔的三个偶联反应中,对炔丙基胺衍生物的合成进行了催化活性研究。
