A 1 2 mixture of l-methyl-3-ethylimidazolium chloride and aluminum trichloride, an ionic liquid that melts below room temperature, has been recommended recently as solvent and catalyst for Friedel-Crafts alkylation and acylation reactions of aromatics (Boon et al., 1986), and as solvent for UV/Vis- and IR-spectroscopic investigations of transition metal halide complexes (Appleby et al., 1986). The corresponding 1-methyl-3-ethylimidazolium tetrachloroborate (as well as -butylpyridinium tetrachlo-roborate) represent new molten salt solvent systems, stable and liquid at room temperature (Williams et al., 1986). 

In 1948, Frank Hurley and Thomas Wier, Jr. [433-436] obtained the first haloaluminate molten salts which melted at room temperature. The authors intended to use these salts as electroplating baths. These first room temperature melts were obtained by combining aluminum chloride with certain organic halide salts. Today, the most useful room temperature molten salts consist of mixtures of aluminum chloride with l-(l-butyl)pyridinium chloride (BPC) or l-methyl-3-ethylimidazolium chloride (MEIC). The structures of BPC and MEIC are given... 

A mixture of l-methyl-3-ethylimidazolium chloride with aluminum chloride also gives an ionic liquid that may be used as electrolytic medium [437]. The medium is not quite inert for example, quinone reacts with an excess of chloride to 2-chlorohydroqui-none in an acid-catalyzed Michael addition [438]. As reference electrode an aluminum wire was used. l-Methyl-3-ethylimidazolium chloride is in MeCN reduced at —2.35 versus Ag in 0.1 M TBAP [439].
