A variety of ionic liquids, each containing the same cation but a different anion, were examined as solvents for a nucleophilic aromatic substitution reaction. Varying the proportion of ionic liquid was found to increase the rate constant as the mole

A range of ionic liquids was examined as solvents for a substitution reaction. They were chosen through rationally varying the ionic liquid cation in order to enhance the rate constant. Access to charge and electron-withdrawing substituents benefitte

X-ray photoelectron spectroscopy (XPS) is a powerful element-specific technique to determine the composition and chemical state of all elements in an involatile sample. However, for elements such as carbon, the wide variety of chemical states produce

A series of nitrogen and phosphorus nucleophiles have been investigated to determine whether the previously established ionic liquid solvent effects on a bimolecular nucleophilic substitution (SN2) reaction vary with the nature of the nucleophilic ce

Ionic liquids have gained significant popularity in recent years as reaction media. Importantly, reaction outcomes (such as rates and selectivities) were shown to vary from traditional solvents. An understanding of such solvent effects in ionic liqui

The nucleophilic aromatic substitution reaction between 1-fluoro-2,4-dinitrobenzene and ethanol was examined in a series of ionic liquids across a range of mole fractions. Temperature-dependent kinetic analyses were undertaken to determine the activa
