The present invention is directed to novel chiral diphosphines (R) or (S) and their use as optically active ligands for preparing diphosphine-metal complexes. The present invention also relates to a diphosphine-metal complex containing the chiral diphosphine (R) or (S), and to the use of the diphosphine-metal complex as a catalyst in a method for asymmetric catalysis of an unsaturated compound having a functional group. .
