Imidazolium salts are the salts of imidazoles where one of the nitrogen atoms in the ring is in the cationic form, e.g. imidazolium chloride. These salts, formed by protonation at the nitrogen atom of imidazole, have been used as ionic liquids and precursors to stable carbenes. Imidazolium salts exhibit good electrical conductivity, high ionic mobility, and excellent chemical and thermal stabilities. Ionic liquids of N,N-dialkylImidazolium salts can be utilized as a reaction media for several organic transformations. Ionic liquids are powerful solvents and electrically conducting fluids.
There are a widely variety of imidazolium salts, ranging from imidazolium chloride salts, N,N-dialkylImidazolium salts, and so on. Imidazolium ions can be deprotonated using anionic bases such as sodium hydride, potassium tert-butoxide, etc. In the electrochemical reduction process, imidazolium salts produce N-heterocyclic carbenes when treated with potassium. The reduction of imidazolium salts is a one- electron process. In addition, Imidazolium bis[(trifluoromethyl)-sulphonyl]amide salts have been recently reported to be distillable.
