Sulfonimides versus ketosulfonamides as epoxidized imidazolium counterions: towards a new generation of ionic liquid monomers

Author affiliations

Abstract

The design of novel ionic liquid monomers with attractive properties represents a real challenge in the field of poly(ionic liquid)s (PILs). Here, we describe a comparative study of the synthesis of original PIL precursors from various sulfonimides or ketosulfonamides as unprecedented counteranions of imidazolium ILs. These salts were submitted to the Prilezhaev reaction and a first insight into the intrinsic properties of these new epoxy monomers was unveiled, in particular the thermal stability of these advanced epoxy salts by comparison with traditional counterions.
