Their parent compounds are often methyimidazolium or pyridinium.
These materials were recently introduced as a stationary phase for capillary gas chromatography columns by Supelco, where they retain polar compounds longer than PEG stationary phases.A variant of the Heck reaction uses one of these compounds, BMIM-PF6 , which removed the need for a phosphorus ligand. A group at the University of Leuven employed one of these compounds in the separation of transition metals from rare earths. Their parent compounds are often methyimidazolium or pyridinium. They result from poorly coordinated ions that have structural difficulty forming a crystal lattice. For 10 points, name these substances that exist as a salt in a certain phase of matter at temperatures below the boiling point of water.
