摘要：
The present invention relates to unsymmetric bidendate organophosphorus ligands of the formula (I) which have a modular structure and have a trivalent phosphine function and a second trivalent phosphorus group which is bound via a heteroatom to a chiral ligand framework, R1R2PZC*HR3XP(YR4)(YR5) (I) where X is —O—, —S— or —NR6—, Y is a direct phosphorus-carbon bond, —O— or —NR7—, Z represents 1 to 6 carbon atoms which are joined by single or double bonds and link the phosphine unit PR1R2 to the carbon center C*, and P is trivalent phosphorus. The invention also relates to complexes comprising such a chiral ligand system of the formula (I).
