<p>Chiral diphosphines constituted by an aromatic pentatomic biheterocyclic system, suitable to act as chiral ligands, complexes between said diphosphines and transition metals, and their utilization as chiral catalysts in stereocontrolled reactions, such as diastereo- and enantioselective reduction reactions. Process for the preparation of said chiral diphosphines and process for the preparation of said complexes and for their utilization as chiral catalysts in stereocontrolled reactions.</p> |
