Popis:	The reaction of 1-hydrohexafluoroisobutenyloxytrimethylsilane (2a) with cesium fluoride in diglyme leads to elimination of trimethylfluorosilane to form the 1-hydrohexafluoroisobutenolate anion (3), which is silylated with trialkylchlorosilanes at the oxygen atom. In the presence of bis(trifluoromethyl)ketene N,N,O-trimethylaminoacetal or N-(α,α-difluoroalkyl)-dialkylamines, silane 2a is transformed into 2,2,2’,2’-tetrakis(trifluoromethyl)divinyl ether. The reaction of trifluoroacetic anhydride with N-(1,1,2,2-tetrafluoroethyl)diethylamine affords trifluoroacetyl fluoride in quantitative yield.
