Aggregation behavior of 1-dodecyl-3-methylimidazolium bromide in aqueous solution: Effect of ionic liquids with aromatic anions

The effects of ionic liquids (ILs), 1-butyl-3-methylimidazolium methylsulfonate (bmimMsa), 1-butyl-3-methylimidazolium benzenesulfonate (bmimBsa), and 1-butyl-3-methylimidazolium 2-naphthalenesulfonate (bmimNsa), on the aggregation behavior of 1-dodecyl-3-methylimidazolium bromide (C 12mimBr) in aqueous solution were investigated by surface tension, dynamic light scattering measurements, and 1H NMR spectroscopy. The ability to promote the surfactant aggregation is in the order bmimNsa > bmimBsa > bmimMsa. Nevertheless, only bmimNsa distinctly reduces both the CMC value and the surface tension at CMC. Due to the penetration of C 10H7SO3-anions into the surfactant aggregate, bmimNsa is found to induce a phase transition from micelles to vesicles, whereas the other ILs only slightly increase the sizes of micelles. The combined effect of intermolecular interactions, such as hydrophobic effect, electrostatic attractions, and π-π stacking interactions, is supposed to be responsible for this structural transformation, in which π-π stacking plays an important role.

SN2 Fluorination reactions in ionic liquids: A mechanistic study towards solvent engineering

In the catalysis of SN2 fluorination reactions, the ionic liquid anion plays a key role as a Lewis base by binding to the counterion Cs + and thereby reducing the retarding Coulombic influence of Cs + on the nucleophile F-. The reaction rates also depend critically on the structures of ionic liquid cation, for example, n-butyl imidazolium gives no SN2 products, whereas n-butylmethyl imidazolium works well. The origin of the observed phenomenal synergetic effects by the ionic liquid [mim-tOH][OMs], in which t-butanol is bonded covalently to the cation [mim], is that the t-butanol moiety binds to the leaving group of the substrate, moderating the retarding interactions between the acidic hydrogen and F-. This work is a significant step toward designing and engineering solvents for promoting specific chemical reactions.

Electrochemical and spectroscopic study of vanadyl acetylacetonate–ionic liquids interactions

A panel of ionic liquids has been synthesized and their effect on the vanadyl acetylacetonate solubility in acetonitrile has been firstly assessed. 1-Butyl-3-methylimidazolium acetate showed an unprecedented result, increasing the VO(acac)2 solubility in acetonitrile of more than one magnitude order (from 0.06 M to 1.1 M) opening new interesting horizons for the possible applications of this vanadium complex. The electrochemical effect of the considered ionic liquids has been subsequently investigated through cyclic voltammetry and linear sweep voltammetry with rotating disk electrode, determining diffusion coefficient and kinetic current of VO(acac)2 in the considered media. In order to achieve a deeper understanding on the examined systems, VO(acac)2 solutions in acetonitrile ILs were eventually studied through IR, UV–vis, and EPR spectroscopies, finding evidences, corroborated by DFT studies, of the formation of strong adducts between VO(acac)2 and ILs.
