Synthesis of Long Chain Internal Alkyn-1-ol Synthons for Imidazolium-Based Ionic Liquids

Nathan in labNathan Neisius (E&H ’19) completed an Honor’s thesis synthesizing ionic liquids. Nathan’s project was to synthesize long chain internal alkyne imidazolium-based ionic liquids to determine how internal alkyne units of unsaturation will affect the properties of the ionic liquids. Nuclear magnetic resonance spectroscopy, thin-layer chromatography, and infrared spectroscopy were utilized to evaluate the efficiency of syntheses. As of now, long chain internal alkyne imidazolium-based ionic liquids have yet to synthesized from this method. Conditions needed for the reactions and work-up have been partially optimized for future research students to finish synthesizing the desired ionic liquids.
