| description | L'invention concerne de nouvelles disphosphines de formule (I) sous forme optiquement pure ou racémique, formule (I), dans laquelle: R1 et R2 représentent un groupe (C5-C7)cycloalkyle, un groupe phényle éventuellement substitué ou un groupe hétéroaryle à 5 chaînons; A représente (CH2-CH2) ou CF2. L'invention concerne également l'utilisation d'un composé de formule (I ) comme ligand pour la préparation d'un complexe métallique, utile comme catalyseur chiral dans la catalyse asymétrique, ainsi que les catalyseurs métalliques chiraux comprenant au moins un ligand de formule (I).
The invention relates to novel diphosphines, in optically pure or racemic form, of formula (I):in which:R1 and R2 are a (C5-C7)cycloalkyl group, an optionally substituted phenyl group or a 5-membered heteroaryl group; andA is (CH2-CH2) or CF2.The invention further relates to the use of a compound of formula (I) as a ligand for the preparation of a metal complex useful as a chiral catalyst in asymmetric catalysis, and to the chiral metal catalysts comprising at least one ligand of formula (I). |
