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

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
Physico-chemical processes in imidazolium ionic liquids.
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
