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.

Neue optisch aktive bis[1-phospha-2,3-diphenyl-4,5-dimethylnorbornadiene ] diphosphines und neue optisch aktive Übergang Metallkomplexe mit besagten phosphines werden beschrieben. Die Komplexe sind nützlich als Katalysatoren, Hydrierung der Substrate zu fördern.
