1,2-Dimethylimidazole is used in the synthesis of 1,2-dimethyl-3-n-butylimidazoliumchloride and 1,2-dimethyl-3-n-propylimidazolium chloride. It also can be used in the synthesis of 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexafluorophosphate salts.
일반 설명
1,2-Dimethylimidazole reacts with copper(II) tetraacetate to yield cis-bis(acetato)bis(1,2-dimethylimidazole) copper(II) complex. It undergoes Menschutkin reaction with benzyl bromide to yield 3-benzyl-1,2-dimethylimidazolium bromide and kinetics of reaction was studied in various ionic liquids and molecular organic solvents.
Purification Methods
Crystallise the imidazole from *benzene, dry and store it at 0-4o. The picrate crystallises from H2O or EtOH with m 181o. [Balaban & Pymann J Chem Soc 125 1570 1924, Gorun et al. J Am Chem Soc 109 4244 1987, Beilstein 23 H 66, 23 II 56, 23 III/IV 594.]
