摘要:

分步合成法了Schiff碱式双反应中心的功能化离子液体: 首先通过1-丙胺基-3-甲基咪唑氯与FeCl3合成含有-NH2的Fe基离子液体; 然后通过1,3-二氨基-2-丙醇与3,5-二叔丁基水杨醛合成Schiff碱配体H2L及其Co配合物CoL, 再通过4-氯丁酰氯的酰氯基与配合物CoL的-OH反应生成含有-CH2Cl的配合物CH2Cl-CoL; 最后通过Fe基离子液体的-NH2与配合物CH2Cl-CoL的-CH2Cl之间的键合反应合成Schiff碱式双功能离子液体. 通过有机元素分析、 红外光谱、 紫外-可见光谱、 核磁共振波谱、 电喷雾电离质谱、 电感耦合等离子体-质谱和拉曼光谱对各化合物进行了结构表征, 确定Schiff碱式双功能离子液体的阳离子为Schiff碱Co络合阳离子, 阴离子为Fe的络合阴离子.

Abstract:

Task-specific Schiff-base ionic liquid with double reactivity centers was prepared by step synthesis. Firstly, Fe-based ionic liquid with the functional group of -NH2 was synthesized by the reaction of 1-propylamine-3-methylimdazolium chloride and FeCl3. Secondly, Schiff-base ligand H2L was prepared by the reaction of 1,3-diamino-2-hydroxypropane and 3,5-di-tert-butylsalicylaldehyde, and its cobalt complex CoL was also prepared. Complex CH2Cl-CoL with the functional group of -CH2Cl was synthesized by the reaction of 4-chlorobutyryl chloride and complex CoL. Finally, task-specific Schiff-base ionic liquid was prepared by the reaction between -NH2 and -CH2Cl of the above two compounds. The compounds synthesized were characterized by elemental analysis, infrared spectrometry(IR), UV-Visible spectroscopy(UV-Vis), 1H nuclear magnetic resonance spectra(1H NMR), Mass spectrometry(MS), inductively coupled plasma mass spectro-metry(ICP-MS) and Raman spectrometry. Task-specific Schiff-base ionic liquid was confirmed to be prepared successfully and to be composed by Schiff-base Co complex cation and Fe complex anion.

Key words: Schiff-base, Fe, Task-specific ionic liquid
