Conclusions
-
1.
2,2,2-Trifluoroethanesulfonic acid has been prepared, as well as a number of its derivatives, viz., its potassium and pyridinium salts, acid chloride, piperidide, amide, and N-mercury salt, and N,N'-bis(2,2,2-trifluoroethanesulfonyl)diaminomethane and N,N′,N″-tris(2,2,2-trifluoroethanesulfonyl)triaminomethane.
-
2.
2,2,2-Trifluoroethanesulfonyl chloride is a CH acid and undergoes dehydrochlorination under base solvolysis conditions to give a hypothetical trifluoromethylsulfonene.
-
3.
Dehydrofluorination of 2,2,2-trifluoroethanesulfonyl fluoride gives 2,2-difluoroethylenesulfonyl fluoride.
