RUTHENIUM COMPLEXES WITH (P-P)-COORDINATED FERROCENYLDIPHOSPHINE LIGANDS, PROCESS FOR PREPARING THEM AND THEIR USE IN HOMOGENEOUS CATALYSIS

摘要

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 Ru complexes are used as catalysts for homogeneous asymmetric catalysis for preparing organic compounds.
