一种树状桥联水杨醛亚胺配体的合成与表征

Synthesis and Characterization of a Dendritic Bridged Salicylaldehyde-imine Ligand

以甲醇为溶剂,将具有配位能力的水杨醛(2)通过Schiff碱缩合反应接枝到整代聚酰胺-胺(1)骨架上,合成了一种树状桥联水杨醛亚胺配体,其结构经1H NMR,IR和元素分析表征。最佳反应条件为:1 4 mmol,n(1)∶n(2)=1∶6,甲醇30 mL,于65℃反应5 h,产率在90%以上。

A dendritic bridged salicylaldehyde-imine ligand were synthesized by Schiff-base condensation reaction of salicylaldehyde（2） grated to the first generation poly（amidoamine） dendrimer（1） in methanol.The structure was characterized by 1H NMR,IR and elemental analysis.The optimum reactions at 65 ℃ for 5 h were as follows： 1 was 4 mmol;n（1） ∶ n（2）=1 ∶ 6;methanol was 30 mL.The yield can be up to 90% under the optimum reactions.
