Conclusions
-
1.
A new equilibrium reaction was found involving transformation of perfluoro-4-oxo-2,5-dimethyl-2-(2′-oxa-3′-fluorocarbonylbutyl)-1,3,-dioxolane into perfluoro-4-oxo-2,5-dimethyl-2-fluorocarbonyl-1, 3-dioxolane and perfluoro-2-oxo-3,6-dimethyl-1,4-dioxane. A scheme for the process is proposed.
-
2.
A catalytic ionic fragmentation was discovered of some perfluoro-4-oxo-1,3-dioxolanes containing a fluoroanhydride group to give trifluoroacetyl fluoride and carbon monoxide.
