Abstract
Chiral diphosphines constituted by an arom. pentat. 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 redn. reactions is described. Process for the prepn. of said chiral disphosphines and process for the prepn. of said complexes and for their utilization as chiral catalysts in stereocontrolled reactions is discussed.
