Optically active diphosphines, preparation thereof according to a process for the resolution of the racemic mixture and use thereof

摘要

New optically active bis[1-phospha-2,3-diphenyl-4,5-dimethylnorbornadiene] diphosphines and new optically active transition metal complexes with said phosphines are described. The complexes are useful as catalysts to promote hydrogenation of substrates.
