The invention concerns novel diphosphines of formula (I) useful in particular, in their optically active form, as ligands in metal complexes. The invention also concerns their uses an intermediates in the preparation of polymeric insoluble ligands. The invention further concerns the use of said insoluble ligands in the preparation of metal complexes for asymmetric catalysis.
La présente invention a pour objet de nouvelles diphosphines de Formule (I) notamment utiles, sous leur forme optiquement active, à titre de ligands dans des complexes métalliques. La présente invention concerne également leurs utilisations comme produits intermédiaires dans la préparation de ligands sous une forme insoluble de type polymérique. L'invention vise également l'utilisation desdits ligands insolubles notamment dans la préparation de complexes métalliques destinés à la catalyse asymétrique.
