Versuchsvorschrift

However, in reality, it can be prepared by reacting tetrafluoroethane-β-sultone, KF and CF2═CFCF2OSO2F without isolating FOCCF2SO2F as the intermediate. Specifically, for example, in the presence of a solvent such as tetraglyme, KF and tetrafluoroethane-β-sultone are reacted under cooling, and CF2═CFCF2OSO2F is dropwise added thereto and reacted, whereby CF2═CFCF2OCF2CF2SO2F can be obtained.
