The syntheses and full spectral (NMR, MS, and IR), thermal (DSC) and ion chromatographic characterization of two series of amine-derived ionic liquids bearing allyl substituents and having chloride or bis(trifluoromethanesulfonyl)amide anions have been presented. The analysis of the dependence of the 1H NMR chemical shift values of the selected protons on the cation and anion structure has been conducted. DSC analysis records together with ion chromatography analysis results have been presented and interpreted. Moreover, a selection of obtained chloride ionic liquids have been transformed into the corresponding chlorocobaltates and chlorozincates or used as substrates in thiol-ene click reactions to indicate their potential as precursors of catalysts or various surface modifiers.

Conventional organic salts represent a new paradigm in many areas of research. Despite their great potential, an improvement in their physicochemical properties requires the chemical modification of their intrinsic structure. Thus, an efficient pathway was developed for the preparation of polyfunctional imidazolium monomers incorporating aromatic rings and terminal epoxides which presented a real synthetic challenge. In this work, we describe the reactivity of various oxidizing agents to develop a strong, clean and powerful methodology to generate epoxidized salts. Various reaction conditions for the formation of the epoxides were investigated such as the role of the cation and the counterion as well as the influence of an aromatic and/or aliphatic linker chain. Finally, we have evaluated the thermal properties of these new polyfunctional salts by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).

We describe the facile, robust and orthogonal fabrication of a structurally comprehensive library of hydrophobic trimethoxysilyl-functionalized ionic liquids with C7-C15 thioether spacer, using thiol-ene "click" chemistry. The synthesized ionic liquids displayed very low glass transition temperatures, high thermal stability and were hydrophobic in character. And the ability to serve as surface coating agents was tested by immobilizing them on the surface of iron oxide supermagnetic nanoparticles and the organic loadings were quantified.
