摘　　要：对价格昂贵的手性催化剂进行回收和重复利用是目前不对称催化领域面临的难题之一,受到学术界和工业界的共同关注。化学家们已经尝试了许多方法,其中使用离子液体来替代常规有机溶剂使催化剂得到分离和重新使用已经引起他们极大的兴趣。本文综述了近年来在离子液体中进行不对称催化反应的研究进展,对离子液体中过渡金属和有机小分子催化的各种反应进行重点介绍,强调了离子液体不但在催化剂回收方面有独特优势,而且在许多反应中能够提高催化效率。The recovery and recycling of expensive chiral catalysts represent one of the most challenging tasks in asymmetric catalysis, and have received increasing attention from both the academy and industry. So far many methods have been tried, and ionic liquid has been regarded as one of the most promising candidates for the facile recovery and reuse of catalysts. In this paper, we summarize the recent progress of asymmetric catalysis in ionic liquids, mainly focus on the reactions catalyzed by transition-metal complexes and organocatalysts, and highight the opportunities that ionic liquids could afford to improve both catalyst recycling and catalytic performance.
