A general halide-to-anion switch for imidazolium-based ionic liquids and oligocationic systems using anion exchange resins (A− form)

Abstract

Further studies on the application of an AER (A⁻ form) method broadened the anion exchange scope of representative ionic liquids and bis(imidazolium) systems. Depending on the hydrophobicity nature of the targeted imidazolium species and counteranions, different organic solvents were used to swap halides for assorted anions, proceeding in excellent to quantitative yields.
