New 1,2,3- or 1,2,3,4- or 1,2,3,4,5- substituted imidazolium salts and their uses asnsolvent in catalyzed organic reactions, as well as compositions containing them and antransition metal compound. They can be used in the following reactions : the telomerisation ofnconjugated dienes, the dimerisation of olefins, the oligomerisation of olefins, thenpolymerization of olefins, the alkylation of olefins, the hydrogenation of olefins, the olefinnmetathesis, the hydroformylation of olefins, the ring-closing metathesis of olefins, the ring-openingnmetathesis polymerisation of olefins, the symetric or asymetric epoxidation of olefinsn(including heteroatom substituted olefins) and the cyclopropanation of olefins, thencondensation reaction, the hydrogenation reaction, the isomerization reaction, the Suzukincross-coupling reactions, the amination reaction, the partial oxidation of alkancs, the kineticnresolution of racemic mixtures, the hydrogenation of imines, the hydrogenation of ketones, thentransfer hydrogenation and the hydroxylation of aromatic organic compounds. |
