IMMOBILISED IMIDAZOLES AND RUTHENIUM CATALYSTS

摘要

The invention relates to a method for the production of N,N-disubstituted imidazolium salts, N-heterocyclic carbene ligands and ruthenium catalysts with N-heterocyclic carbene ligands, in other words, compounds of general formulae (I) and (II), compounds of general formulae (III) and (IV) and compounds of general formulae (V) and (VI), (I - VI), immobilised on inorganic oxide supports. The invention further relates to the use of the immobilised compounds of general formulae (I - IV) in organic, metalloorganic or transition metal catalysed synthesis and the use of the compounds of general formulae (V) and (VI) as catalysts in organic and metalloorganic synthesis, in particular for C-C coupling reactions as in olefin metasynthesis.
