Conclusions
-
1.
Perfluoropropylene oxide reacts with sulfur trioxide at 150° to give two isomeric products: 1,2 perfluoropropylene sulfate and 2-oxoperfLuoropropyl fluorosulfate. A cyclic synchronous mechanism was proposed for the formation of 2-oxoperfluoropropyl fluorosulfate.
-
2.
The reaction of water, an alcohol, or aniline with 1,2-perfluoropropylene sulfate or 2-oxoperfluoropropyl fluorosulfate gave the correspondingα-hydroxy-α-substituted perfluoropropionic acid derivatives.
-
3.
The treatment of 1,2-perfluoropropylene sulfate or 2-oxoperfluoropropyl fluorosulfate with catalytic amounts of KF or CsF in acetonitrile or diglyme results in the evolution of SO2F2 and the formation of perfluoropyruvoyl fluoride.
