Environmentally Friendly Approach

The design of the environmentally friendly approach to the synthesis of biologically important compounds without compromising the yield has been the focus of many chemists in recent years. The development of the one-pot synthesis of heterocycles in the presence of Ionic Liquids (ILs), used as both environmental media and catalysts, is efficient and environmentally sustainable. This review highlights the one-pot synthesis of imidazoles in acidic ILs in the past decade. Some reviews have been conducted on imidazoles, such as their pharmacological importance. Hence, we decided to focus on their synthesis in acidic ionic liquids, which the authors are not aware of any published literature.

AbstractTriethanol ammonium acetate ([TEAH]+[OAc]−) and triethanol ammonium formate ([TEAH]+[HCOO]−) as multifunctional ionic liquids and catalysts were successfully applied for the preparation of tetrahydrobenzo[b]pyrans by the one-pot three-component condensation reaction of various aldehydes, dimedone and malononitrile under solvent-free conditions. These reactions were also tested using boric acid in water. In this catalytic system, by the reaction of water with boric acid, the hydronium ion caused by water separation can catalyze the reaction.

Biginelli Condensation

Novel SO3H-functionalized ionic liquids were successfully applied as catalysts for the one-pot three component Biginelli condensation under ultrasound irradiation without solvent. Various types of 3,4-dihydorpymidine(1H)-(thio)-ones were provided in 84-98% yields and conveniently separated from the reaction mixture by filtration, the dissolved catalyst could be reused with simple treatment. This novel synthetic method is especially favoured because it provides a synergy between ionic liquids and ultrasound irradiation which offers the advantages of high yields, short reaction times, simplicity, and easy workup compared to the conventional methods reported in the literature

Nitrogen Doped Carbon

ABSTRACTIonic liquids (ILs) are highly suitable to act as precursors for nitrogen-doped carbon materials. Therefore two structural requirements must be fulfilled: On the one hand, the cation should carry nitrogen in a preferably aromatic environment, on the other hand nitrile groups are essential that can be e.g. incorporated by dicyanamide anions. Thermolysis of such ILs yields highly conductive nitrogen doped carbon exhibiting a graphitic microstructure. Furthermore, various nanomorphologies can be induced via hard-templating. The material has been shown to sufficiently suppress growth and agglomeration of Pt nanoparticles upon their electrocatalytic performance, when applied as a thin coating on the Pt host material. This novel concept of reactivity could further be applied in other fields of materials synthesis, paving the way for the one-pot synthesis of mesoporous carbon/silica composites and in-situ metal doping thereof.
