New 1,2,3- or 1,2,3,4- or 1,2,3,4,5- substituted imidazolium salts and their uses as solvent in catalyzed organic reactions, as well as compositions containing them and a transition metal compound. They can be used in the following reactions: the telomerisation of conjugated dienes, dimerisation of olefins, the oligomerisation of olefins, polymerization of olefins, alkylation of olefins, hydrogenation of olefins, olefin metathesis, hydroformylation of olefins, ring-closing metathesis of olefins, ring-opening metathesis polymerisation of olefins, symetric or asymetric epoxidation of olefins (including heteroatom substituted olefins) and the cyclopropanation of olefins, condensation reaction, hydrogenation reaction, isomerization reaction, Suzuki cross-coupling reactions, amination reaction, partial oxidation of alkancs, kinetic resolution of racemic mixtures, hydrogenation of imines, hydrogenation of ketones, transfer hydrogenation and hydroxylation of aromatic organic compounds.
