Synthesis And Reactions Of Fluoroalkanesulphonamides And Bis(Fluoroalkanesulphon)amides Compounds

"Superacids", those stronger than 100% sulfuric acid, have been of great value to chemistry. In recent years, the bis(perfluoroalkanesulphon)amides complexes , which belong to superacid compounds, have been attracted great interest in development of science. They are widely used in organic synthesis as catalysts for Diels–Alder reaction and Friedel–Crafts reaction. Other applications were also found in ionic liquids and batteries. The abroad application of bis(perfluoroalksulphon)amides complexes results from the excellent property called as"Weakly-coordination"or"Noncoordination".Bis(ω–iodide–γ–oxy–octfluoropensulfony)amide is a special"superacid".It might be hopefully modified to some multifunctional derivatives which can be used as ionic liquids and batteries etc. In attempt to find out the method of synthesis the special"superacids"and probe into the properties of them, bis(ω–iodide–γ–oxy–octfluoropensulfony)amide and some derivatives, such as bis(ω–hydro–γ–oxy–octfluoropensulfony)amide and so on, have been prepared fromω–fluorosulfonylperfluoroalkyl iodide .In order to exploit more useful"superacids", we have been attempted to prepare bis(2–chloro–tetra–fluoroethanesulfonyl)amid by 2–chloro–1,1,2,2–tetrafluoroethanesulfonyl chloride, and have get some achievement.
