摘要：

A series of hydroxyl-functionalized ionic liquids (HFILs) were synthesized and characterized. They showed efficient reactivity and reusability toward the coupling of epoxide and CO2 without any additional co-catalyst and organic solvent. Highest activity and selectivity were achieved in the presence of 1-(2-hydroxyl-ethyl)-3-methylimidazolium bromide (HEMIMB) in comparison with other similar catalysts investigated. The relationship between the higher catalytic reactivity and OH-functional group was proposed. (C) 2008 Elsevier Ltd. All rights reserved.
