反应控制相转移催化剂的研究进展

Research Progress in Reaction-Controlled Phase Transfer Catalysts

反应控制相转移催化兼具均相和非均相催化的优点,有助于解决催化剂催化活性低及分离回收困难等问题,符合环境友好的要求,所以一直以来备受关注。反应控制相转移现象的形成与催化剂的阴、阳离子结构和溶剂等反应条件密切相关。本文就目前应用广泛的反应控制相转移催化剂的阴、阳离子的结构特点进行综述,最后就反应控制相转移催化体系可能存在的问题和创新方向作了展望。

The reaction-controlled phase-ransfer catalysis has the advantages of homogeneous and heterogeneous catalysis.It can resolve the problems of low catalytic activity and recovery difficulty of the catalyst,which meets environmentally friendly requirements.So,the reaction-controlled phase-transfer catalysis has been receiving much attention.The reaction-controlled phase-transfer phenomenon is closely related to the structures of catalyst anion and cation,and reaction conditions such as solvent.In this paper,the structural features of anion and cation of reactioncontrolled phase-transfer catalysts in the widely used reactions are reviewed.Finally,the possible problems and innovation of the current reaction-controlled phase-transfer catalytic systems are proposed,and the development prospects are also forecasted.
