CHIRAL DIPHOSPHINES AND THEIR METAL COMPLEXES

摘要

The invention concerns novel chiral diphosphines (R) or (S), and their use as optically active ligand for preparing diphosphino-metallic complexes. The invention also concerns the diphosphino-metallic complexes containing said chiral diphosphines (R) or (S), and the use of said diphosphino-metallic complexes as catalyst in asymmetric catalysis of unsaturated compounds bearing functional groups.
