固载化离子液体的制备及其在有机反应中的应用进展

Progress in preparation of supported ionic liquids and its application in organic reactions

固载化离子液体是通过物理吸附或化学键合的方法将离子液体与载体结合形成的一种固体催化剂,既保留了离子液体优良的催化活性,又结合了载体高比表面积的特性,从而有效降低了离子液体的用量,还提高了催化剂的重复使用性能,因而被广泛应用于有机反应中。综述了近几年来国内外有关载体材料分类、固载化离子液体的制备及其在偶联、环化、缩合、氧化等反应中应用的研究进展。

Supported ionic liquids are a kind of solid catalysts which are the combination of the ionic liquids and supports through physical adsorption and chemical bonding.The catalysts not only retain the excellent catalytic activity of ionic liquids,but also combine the characteristics of the high specific surface area of the supports,effectively reducing the amount of ionic liquids and improving the reusability of catalysts,thus are widely applied in organic reactions.In this paper,the classification of supported material,preparation of supported ionic liquids and its applications in organic reactions such as coupling reaction,cyclization reaction,condensation reaction,oxidation reaction and so on,were reviewed.
