Abstract

The invention relates to ruthenium complexes with a chiral ferrocenyldiphosphine ligand, wherein the ruthenium has the oxidation state (+II) and the chiral ferrocenyldiphosphine ligand has bidentate P—P coordination to the ruthenium. The ruthenium complexes are cyclic and with the ferrocenyldiphosphine ligand have an at least eight-membered ring. The ferrocenyldiphosphine ligands are selected from the group consisting of Taniaphos, Taniaphos-OH and Walphos ligands. A process for preparing the Ru complexes is described. The Rn complexes are used as catalysts for homogeneous asymmetric catalysis for preparing organic compounds.
