IMIDAZOLIUM SALTS AND THEIR USE OF THESE IONIC LIQUIDS AS A SOLVENT

摘要

New 1,2,3- or 1,2,3,4- or 1,2,3,4,5- substituted imidazolium salts and theiruses as solvent in catalysed organic reactions, as well as compositionscontaining them and a transition metal compound. They can be used in thefollowing reactions: telomerisation of conjugated dienes, dimerisation ofolefins, oligomerisation of olefins, polymerization of olefins, alkylation ofolefins, hydrogenations of olefins, olefin metathesis, hydroformylation ofolefins, ring-closing metathesis of olefins, ring-opening metathesispolymerisation of olefins, symmetric or asymmetric epoxidation of olefins(including heteroatom substituted olefins) and cyclopropanation of olefins,condensation reaction, hydrogenation reactions, isomerisation reaction, Suzukicross-coupling reactions, amination reaction, partial oxidation of alkanes,kinetic resolution of racemic mixtures, hydrogenation of imines, hydrogenationof ketones, transfer hydrogenation and hydroxylation of aromatic organiccompounds.
