Patent

CA 2429252

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.

La présente invention a pour objet de nouvelles diphosphines chirales (R) ou (S), et leur utilisation comme ligand optiquement actif pour la préparation de complexes diphosphino-métalliques. L'invention concerne aussi les complexes diphosphino-métalliques comprenant lesdites diphosphines chirales (R) ou (S), ainsi que l'utilisation desdits complexes diphosphino-métalliques comme catalyseur dans des procédés de catalyse asymétrique de composés insaturés porteurs de groupements fonctionnels.
