This work reports the voltammetric behaviour of decamethylcobaltocenium, DmCc(+), in different ionic liquids for the first time. Its redox potential was studied relative to that of decamethylferrocene, DmFc, and it is shown that the difference in the mid-point potential between these two permethylated transition-metal sandwich complexes is independent of the ionic liquid composition. A variable...

Surfactants responsive to pH, temperature, CO2, [3] and light are well known. Here we report for the first time ionic liquid surfactants that are magneto-responsive, thus offering the potential to perturb liquid emulsions simply by the application of an external magnetic field. Although ionic liquids (ILs) containing transition metal complexes have been known for some time, it had always been a...

Carbon dioxide (CO2) is one of the major contributors to the greenhouse effect. The power and industrial sectors combined account for about 60% of the global CO2 emissions [1]. CO2 capture and storage (CCS), which involves the processes of capture, transport and long-term storage of carbon dioxide, is a technology aimed at reducing greenhouse gas emissions from burning fossil fuels during indus...

Ionic liquids (ILs) have been proven to be valuable reaction media for the synthesis of inorganic materials among an abundance of other applications in different fields of chemistry. Up to now, the syntheses have remained mostly "black boxes"; and researchers have to resort to trial-and-error in order to establish a new synthetic route to a specific compound. This review comprises decisive reac...

A new mathematical model has been developed that expresses the toxicities (EC₅₀ values) of a wide variety of ionic liquids (ILs) towards the freshwater flea Daphnia magna by means of a quantitative structure-activity relationship (QSAR). The data were analyzed using summed contributions from the cations, their alkyl substituents and anions. The model employed multiple linear regression analysis...

Now that many scientific investigations focus on ionic liquids (IL) to establish their potential in different chemical processes, their application for the separation of various classes of compounds in capillary electrophoresis has also been recognized. ILs have been used as background electrolytes in aqueous and non-aqueous capillary electrophoresis for the separation of a number of different ...

The magnetic field effects (MFEs) on photoinduced hydrogen abstraction reactions of benzophenone (BP) with thiophenol (PhSH) in the ionic liquids (ILs) N,N,N-trimethyl-N-propylammonium bis(trifluoromethanesulfonyl) imide (TMPA TFSI), N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl) imide (P13 TFSI), and N-methyl-N-propylpiperidinium bis(trifluoromethanesulfonyl) imide (PP13 TFSI) we...

This work presents an approach toward the shape-controlled synthesis of Ag crystals with hierarchical structures by exploitation of ionic liquids (ILs) as a shape-regulating agent. The synthesis of Ag crystals involves the reduction of AgNO(3) by EG in the presence of ILs, specifically 1-butyl-3-methylimidazolium methylsulfate (bmim-MeSO(4)). In accordance with non-classical crystallization gro...

Green chemistry plays a very important role in the sustainable development, seeking to reduce and prevent pollution at its source, minimizing the hazard and maximizing the efficiency of the chemical processes. Ionic liquids (ILs) are a new generation of chemicals that have a great potential for contributing to the greenness of chemical processes and developing new applications, both being of in...

The efficacy of [bmim][X] ionic liquids (ILs) (X = PF(6) (-), BF(4) (-) and NTf(2) (-)) as reaction media for methyl oleate metathesis was compared with that of conventional organic solvents (PhCl, PhMe, DCM and DCE) using the well-defined first and second generation Grubbs precatalysts, RuCl(2)(PCy(3))(L)(=CHPh) (L = PCy(3) or H(2)IMes). Best catalytic performance, with excellent selectivity (...
