中文摘要: 随着低碳经济呼声的日益增强,CO2的资源化利用引起了政府、学术界和工业界的广泛关注。本项目利用离子液体结构可设计修饰的特点,研制适合催化活化CO2的含脲、碱性以及酸碱双功能离子液体;考察功能化离子液体催化CO2、环氧化合物和有机胺的反应性能,开发一种化学固定CO2并高效、高选择性地合成含氮杂环化合物的方法。利用原位技术(NMR、ESI-MS)和理论计算表征和模拟功能化离子液体与CO2等反应底物的相互作用,提出离子液体催化活化CO2的模型和反应机理。该项目的顺利实施对揭示C-O键的活化规律、探索离子液体催化转化CO2合成精细化学品的新过程、促进CO2的固定和循环具有重要意义。

英文摘要: The utilization of CO2 as a feedstock for the production of organic products continues to receive attention of government, scientists and industry. In this project, ionic liquids containing urea, base, and acid/base groups which suitable for CO2 activation will be designed and synthesized. These functionalized ionic liquids will be used to catalyze the conversion of CO2 to synthesize heterocyclics, such as substituted oxazolidinones, imidazolidione and so on. This novel procedure will provide a new method for fixing CO2 high effectively and selectively. The interaction of functional ionic liquids and CO2 and other reactants will be investigated by in-situ NMR, ESI-MS and density functional theory (DFT) calculation. Based on these investigations, we will propose the CO2 activation mechanisms by functional ionic liquids. The success implement of the project will have an important influence on revealing the law of CO2 activation and provide a new route for CO2 fixation and circulation.
