| | 2-Chloro-1,3-dimethylimidazolidinium hexafluorophosphate Usage And Synthesis |
| Synthesis | Potassium hexafluorophosphate (1.32 g, 7.2 mmol) was added to a solution of 2-chloro-1,3-dimethyl-2-imidazolium chloride (1.24 g, 7.3 mmol) in dry acetonitrile (2 mL). The reaction mixture was then stirred at room temperature for 10 minutes. After the reaction was complete, the mixture was filtered through a diatomaceous earth filter to remove insoluble solids. The filtrate was then concentrated under vacuum, and the residue was dissolved in a small amount of acetonitrile (approximately 2 mL). The solution was then poured into diethyl ether, and a significant precipitate was observed to form in the reaction mixture. The precipitate was collected by vacuum filtration to obtain the target product, 2-Chloro-1,3-dimethylimidazolidinium hexafluorophosphate.
