Ionic liquids (ILs) are materials with outstanding physico-chemical properties: negligible vapor pressure, high polarity and high thermal and electrochemical stability. ILs have been successfully used in catalysis (both as solvent and co-catalyst), in electrochemistry, or in the extraction of transition metals. We herein report the synthesis, characterization and application of a new imidazolium-based class of ILs, namely the tunable aryl alkyl ionic liquids (TAAILs). In comparison with all-alkyl imidazolium-based ILs, the introduction of the aryl moiety enhances π-π interactions and steric effects which results in ILs with a high level of structural modularity and thus high versatility in the physico-chemical properties. Due to these structure-driven characteristics together with their high thermal stability, TAAILs are excellent solvents in transition metal catalyzed reactions.
