Use of ionic liquids as solvents in base-catalysed chemical reactions wherein the ionic liquid is composed of at least one species of cation and at least one species of anion, characterised in that a cation of the ionic liquid comprises a positively charge moiety and a basic moiety, and further wherein such ionic liquids may be used as promoters or catalysts for the chemical reactions.
Use of ionic liquids in the production of bio-diesel, wherein the ionic liquid is both a solvent and catalyst, and is stable under reaction conditions.

A simple and efficient synthesis of a novel series of ionic liquids bearing nucleophilic (Me2N) and non-nucleophilic base (iPr2N) functionalities is described. The non-nucleophilic base functionality resembles the structure of the Hünig's base (N,N-diisopropylethylamine), which has been used widely in organic synthesis. A qualitative measure of the basicity of these ionic liquids is presented by utilising their interaction with universal indicator. The basicity of these ionic liquids was found to be dependent on the amine tether and choice of linker between the two nitrogen centres. The relative base strength of these ionic liquids was also probed by using them as catalysts in the Heck and Knoevenagel reactions.
