제목 Catalytic Fixation of Carbon Dioxide with Epoxides Promoted by Hydrogen Bond-based Ionic Liquids
초록 Chemical fixation of CO2 into cyclic carbonates has attracted extensive attention in both academia and industry. Its use on an industrial scale represents a much greener alternative to the use of phosgene. Various catalysts including ionic liquids (ILs) have been developed for the cycloaddition reaction. However, unsatisfactory activities, high cost, low water/thermal stabilities of catalysts as well as the requirement of organic solvent (DMF, toluene or CH2Cl2) and metal salts (ZnCl2) as co-catalysts are still the disadvantages needed to be overcome. Current progress has found that hydrogen bond donors could activate the epoxides and enhance the reaction for conversion of CO2 with epoxides, which observed positive influence in the presence of metal salts or quaternary onium salts. In this work, we designed and synthesized hydroxyl-functionalized ILs for cycloaddition of CO2 and epoxides based on understanding of reaction mechanism, which exhibited high activity for this reaction without any solvent and co-catalyst.
