Abstract
New ionic liquids containing ( 2- hydroxypropyl)- functionalized imidazolium cations have been synthesized by the atom- efficient, room temperature reaction of 1- methylimidazole with acid and propylene oxide; the acid providing the anionic component of the resultant ionic liquids. The incorporation of the secondary hydroxyl- functionality in the cation causes some interesting modifications to the behavior of these ionic liquids, increasing hydrophilicity and resulting in the unprecedented formation of liquid - liquid biphases with acetone. The single crystal structure of 1-( 2- hydroxypropyl)- 3- methylimidazolium tetraphenylborate, prepared by metathesis of the corresponding chloride- containing ionic liquid, has also been determined.
