To date, the major challenge in preparing perfluoroalkoxides is the high reactivity and toxicity of the starting materials and the inherent propensity for the elimination of metal fluorides. In our recent work, we will report on a method to readily form anhydrous non-metal based perfluoroalkoxides in a single step using relatively inexpensive and easy to use reagents, which include the use of hydrofluoroethers (HFEs). This methodology would allow for a simple incorporation of fluorinated alkoxides into many synthetic reactions. A historical review of hydrofluoroethers will be discussed as well as strategies to adopt HFEs in anionic ring-opening polymerization of fluorinated epoxides for control of molecular weight.
