Abstract
The invention relates to ferrocenyldiphosphine ligands containing a silylene group, ferrocenyldiphosphines bound to inorganic or polymeric organic supports by this silylene group, their preparation and also their metal complexes with transition metals such as rhodium or iridium. The invention also relates to the use of these complexes for hydrogenating organic double or triple bonds, in particular olefinic double bonds and carbon-heteroatom double bonds. The complexes are particularly suitable for enantioselective hydrogenation using chiral diphosphines and prochiral unsaturated compounds.
