1-Butylimidazole-derived ionic liquids: Synthesis, characterisation and evaluation of their antibacterial, antifungal and anticancer activities

A series of new 1-butylimidazole-based ionic liquids (3a-h) have been synthesised by the quaternisation reaction of 1-butylimidazole with different alkyl- and alkoxy-substituted aryl halides using a microwave solvent-free approach with ≈82-95% yield. The

Phenolic hydroxyl-functionalized imidazolium ionic liquids: Highly efficient catalysts for the fixation of CO2 to cyclic carbonates

A series of imidazolium ionic liquids were designed and synthesized by the reaction of imidazole derivatives with alkyl bromides. These ionic liquids were applied to catalyze the reaction of CO2 and epoxides. A detailed investigation was carried out on the relationship between catalytic activities and catalyst structures. The result showed that phenolic hydroxyl-functionalized imidazolium ionic liquids containing both phenolic hydroxyl and C2-H were highly efficient catalysts. Meanwhile, the spatial positions of the phenolic hydroxyl and C2-H in the imidazolium also exhibited great effect on the catalytic efficiencies, and the order of catalytic activity was meta-isomer > ortho-isomer > para-isomer. NMR titration and DFT calculations showed a synergetic effect, which C2-H and phenolic hydroxyl cooperatively activated epoxides by hydrogen bonds, was crucial for the reaction to proceed smoothly under mild conditions. In addition, the TOF of the most active catalyst 3-(3-phenolic hydroxyl)-1-butyl-imidazolium bromide (IL-2) reached to 900 h-1 in the reaction of CO2 and epichlorohydrin under the reaction conditions of 0.1 mol% catalyst, 1 MPa CO2, 120 °C and 1 h.

Convenient syntheses of bulky group containing imidazolium ionic liquids

We report syntheses of bulky group containing imidazolium based ionic liquids. The bulky groups were introduced at N-1, C-2, and N-3 positions of the imidazole ring using convenient methodologies. Copyright

Synthesis of aryl azides: A probe reaction to study the synergetic action of ultrasounds and ionic liquids

The combined effect of ultrasounds and ionic liquids was used to perform the synthesis of aryl azides by nucleophilic aromatic substitution in ionic liquid/[1-butyl-3-methylimidazolium][N3] binary mixtures. The ultrasounds efficiency was analyz

The effect of the cation π-surface area on the 3D organization and catalytic ability of imidazolium-based ionic liquids

The dichotomic nature of ionic liquids (ILs, simple solvents or supramolecular fluids) induced us to carry out a structural investigation of some mono-and dicationic ionic liquids using 1D and 2D NMR, resonance light scattering, and UV/Vis spectroscopy. I

Design of reaction media for nucleophilic substitution reactions by using a catalytic amount of an amphiphilic imidazolium salt in water

Molecules of an amphiphilic imidazolium salt assemble in water to form a hydrophobic membrane including an interface consisting of ammonium species. Such an interface works as a reaction medium like an ionic liquid. We used the medium for nucleophilic substitution reactions between alkyl halides and anionic nucleophiles. This procedure allowed the reactions to proceed efficiently in water without any organic solvent.
