线型聚氧乙烯化合物具有良好的相转移催化能力。以其作为相转移催化剂,不仅来源丰富,价廉无毒,化学稳定性好,而且反应条件温和,操作简便,产率也较高,是相转移催化反应中理想的冠醚替代物。文中综述了线型聚氧乙烯化合物作为相转移催化剂在有机合成中的应用进展,并对其相转移催化作用进行了讨论。 Linear polyoxyethylene compounds have good phase transfer catalysis. As its phase transfer catalyst, it is not only rich in source, cheap and nontoxic, with good chemical stability, but also mild reaction conditions, easy operation and high yield. It is an ideal substitute for crown ether in phase transfer catalysis reaction. In this paper, advances in the application of linear polyoxyethylene compounds as phase transfer catalysts in organic synthesis are reviewed. Their phase transfer catalysis is also discussed.
