Three novel anions based on pentafluorophenyl amine combined with two new synthetic strategies for the synthesis of highly lipophilic ionic liquids

The three new fluorinated anions BPFPA, PFTFSI, and PFNFSI for highly hydrophobic, hydrolytically stable ionic liquids are introduced, together with a strategy allowing a combinatorial approach for the synthesis of imidazolium and phosphonium based ionic liquids of these relatives of bistriflylimide (BTFSI).
