Synthesis and Physicochemical Properties of Bis(fluoroalkanesulfon)amide-Based Ionic Liquids

A series of bis(fluoroalkanesulfon)amides were synthesized in good yield from the reaction of fluoroalkanesulfonamides and fluoroalkylsulfonyl fluorides. Ionic liquids based on these amide anions and an imidazolium cation demonstrated high densities and a wide temperature range for the liquid state. A series of bis(fluoroalkanesulfon)amides were synthesized in good yield from thereaction of fluoroalkanesulfonamides and fluoroalkylsulfonyl fluorides. Combinationof these amide anions with imidazolium cations afforded a variety of novel ionic liquids, which demonstrated high densities and wide liquid range.
