| Ionic liquids have attracted interest in recent years as replacements for volatile organic solvents. However, few papers contribute to an understanding of how ionic liquids effect reactions, and so it is difficult to predict circumstances in which specific ionic liquids may be of use. In order for the full potential of these novel solvents to be fulfilled, possible structure activity relationships must be investigated. This poster outlines one possible approach to the problem, the investigation of correlations between physical properties of ionic liquids and effects seen in acid catalysed reactions. In particular the poster conveys ongoing work on Kamlet-Taft polarity measurements, Hammett acidity measurements and a Fries rearrangement reaction, using a range of ionic liquids. By studying a range of acid catalysed reactions in ionic liquids and comparing differences observed in reaction outcomes (e.g. rate, yield, selectivity) to the aforementioned physical measurements a further understanding will be attained. |
