On the solid, liquid and solution structural organization of imidazolium ionic liquids
Sais derivados do cation 1,3-dialquilimidazolio sao uma das mais populares e investigadas classes de liquidos ionicos a temperatura ambiente. Embora, em varios casos, suas propriedadesExpand
Ionic liquid (molten salt) phase organometallic catalysis.
The advent of water-soluble organometallic complexes, especially those based on sulfonated phosphorus-containing ligands, has enabled various biphasic catalytic reactions to be conducted on an industrial scale and might combine the advantages of both homogeneous and heterogeneous catalysis. Expand
Transition-metal nanoparticles in imidazolium ionic liquids: recyclable catalysts for biphasic hydrogenation reactions.
Ir(0) nanoparticles with a mean diameter of 2 nm have been prepared by reduction of Ir(I) dissolved in the ionic liquid with H2 so that this catalytic solution can be reused several times for the biphasic hydrogenation of olefins under mild reaction conditions. Expand
The use of new ionic liquids in two-phase catalytic hydrogenation reaction by rhodium complexes
Abstract The reaction of 1-n-butyl-3-methylimidazolium chloride (BMIC) with sodium tetrafluoroborate or sodium hexafluorophosphate produced the room temperature-, air- and water-stable molten saltsExpand
On the structural and surface properties of transition-metal nanoparticles in ionic liquids.
In this critical review, the structural/surface properties of these soluble metal NPs dispersed in ILs and their application in catalysis and as chemical sensors are discussed, with particular attention paid to the stabilisation models proposed to explain the stability and properties ofTheseMetal NPs.

A journey into a nanostructured universe to better understand the unique properties of ionic liquids and their modern applications is described and it is explained why modern nonaqueous ILs deserve increased interest and curiosity. Expand
Catalytic applications of metal nanoparticles in imidazolium ionic liquids.
Metal nanoparticles with a small diameter and narrow size distribution that can be prepared by H(2) reduction of metal compounds or decomposition of organometallic species dissolved in ionic liquids (ILs) are catalysts for reactions under multiphase conditions. Expand

Reaction paths that involve charge-separated intermediates or transition states are accelerated--by lowering the activation barrier-in the presence of ILs when compared with those performed in classical organic solvents. Expand
Identification of 1,3-dialkylimidazolium salt supramolecular aggregates in solution.
The nature of the interactions between 1,3-dialkylimidazolium cations and noncoordinating anions such as tetrafluoroborate, hexafluorophosphate, and tetraphenylborate has been studied in the solid state and in solution by X-ray diffraction analysis, conductivity, and microcalorimetry. Expand
