全氟(多氟)烯烃环氧化技术进展

Progress in Preparation of Fluorooxiranes by Alkene Epoxidation

全氟(多氟)取代的环氧化合物不仅在合成和工业应用中是非常关键的单体和中间体,而且在新材料的开发应用中也有广泛的应用。本文针对其对应烯烃的环氧化技术展开综述。文中根据氧化剂的不同把环氧化体系分为NaClO体系、H_2O_2体系、O_2体系、HOF/H_2O/MeCN体系、tert-N-O体系和CrO_3/FSO_3H体系等等,依次展开分类论述并进行了比较。

Fluorinated oxiranes not only act as monomers and intermediate products for the synthetic and industrial application, but also widely used in developing new technology materials. This review discussed the preparation of highly fluorinated oxiranes by epoxidize the corresponding olefins. Depending on the different oxidants, several oxidation systems were reviewd, like sodium hypochlorite oxidation systems,hydrogen peroxide oxidation systems,molecular oxygen oxidation systems,fluorine/water/acetonitrile system, tert-amine N-oxide oxidation systems, et al.
