MIXTURES OF CHIRAL MONOPHOSPHORUS COMPOUNDS USED AS LIGAND SYSTEMS FOR ASYMMETRIC TRANSITION METAL CATALYSIS

摘要

The invention relates to certain chiral transition metal catalysts, to the metal of which at least two structurally different monophosphorus ligands are bonded, at least one of said monophosphorus ligands being chiral. Said chiral transition metal catalysts are suitable as catalysts for use in asymmetric transition metal-catalyzed reactions, providing better enantioselectivities than in cases where only one structurally defined ligand is used.
