HCID 1072222,3,3,3-Tetrafluoro-2-(1,1,2,2-tetrafluoro-2-(fluorosulphonyl)ethoxy)propionyl fluoride

Procedure

FSO2CF2CF2COF obtained in Example 1-6, CsF powder and diglyme are charged into an autoclave, and hexafluoropropene oxide is introduced with stirring under cooling with ice. Stirring is continued for 1 hour, and the content in the autoclave is distilled under reduced pressure to obtain FSO2CF2CF2OCF(CF3)COF.
