Use of optically active diphosphines as chiral ligands for the preparation of complexes diphosphino - metal, the complexes thus obtained and by catalysis asymmetric the implementing

摘要

The invention concerns the use of chiral diphosphines as optically active ligands for preparing diphosphino-metal complexes. The invention also concerns diphosphino-metal complexes comprising a chiral diphosphine as ligands and asymmetrical catalysis methods using said complexes. More particularly, the invention concerns the use of said diphosphino-metal complexes in asymmetrical hydrogenation or isomerization processes for the synthesis of organic products with desired chirality.
