The invention relates to the bisphosphites of the general formula(I), wherein R1, R2, R3, R4, R5, R6 represent H, an aliphatic, alicyclic, aliphatic- alicyclic, heterocyclic, aliphatic-heterocyclic, aromatic, aliphatic-aromatic hydrocarbon group with 1 to 50 carbon atoms, F, Cl, Br, I, -OR7, -COR7 -CO2R7, -CO2M, -SR7, -SO2R7, -SOR7, -SO3R7, -SO3M, -SO2NR7R8, NR7R8, N=CR7R8, NH2, wherein R1 to R6 are the same or different and can be covalently linked with each other, R7, R8 represent H, a substituted or unsubstituted, aliphatic or aromatic hydrocarbon group with 1 to 25 carbon atoms, which are the same or different, M represents an alkali metal, alkaline earth metal, ammonium, phosphonium ion; Q represents a bivalent, aliphatic, alicyclic, aliphatic- alicyclic, heterocyclic, aliphatic-heterocyclic, aromatic, aliphatic-aromatic hydrocarbon group with 1 to 50 carbon atoms, W, X represent aliphatic, alicyclic, aliphatic-alicyclic, heterocyclic, aliphatic-heterocyclic, aromatic, aliphatic-aromatic hydrocarbon groups with 1 to 50 carbon atoms, which are the same or different or which are covalently linked with each other. The invention further relates to the metal complexes of said bisphosphites and to the use thereof in hydroformylation reactions.

L'invention concerne des biphosphites de formule générale (I) Formel (I) dans laquelle R?1¿, R?2¿, R?3¿, R?4¿, R?5¿, R?6¿ désignent un H, un reste hydrocarbure aliphatique, alicyclique, aliphatique-alicyclique, hétérocyclique, aliphatique-hétérocyclique, aromatique, aliphatique-aromatique de 1 à 50 atomes de carbone, F, Cl, Br, I, -OR?7¿, -COR?7¿ -CO¿2?R?7¿, -CO¿2?M, -SR?7¿, -SO¿2?R?7¿, -SOR?7¿, -SO¿3?R?7¿, -SO¿3?M, -SO¿2?NR?7¿R?8¿, NR?7¿R?8¿, N=CR?7¿R?8¿, NH¿2?, où R?1¿ à R?6¿ qui sont identiques ou différents, peuvent être liés entre eux par covalence, R?7¿, R?8¿ désignent un H, un reste hydrocarbure aliphatique ou aromatique, substitué ou non, de 1 à 25 atomes de carbone, et peuvent être identiques ou différents, M désigne un ion métal alcalin, métal alcalino-terreux, ammonium, phosphonium, Q désigne un reste hydrocarbure bivalent, aliphatique, alicyclique, aliphatique-alicyclique, hétérocyclique, aliphatique-hétérocyclique, aromatique, aliphatique-aromatique de 1 à 50 atomes de carbone, W, X désignent un reste hydrocarbure aliphatique, alicyclique, aliphatique-alicyclique, hétérocyclique, aliphatique-hétérocyclique, aromatique, aliphatique-aromatique de 1 à 50 atomes de carbone, et peuvent être identiques ou différents ou liés entre eux par covalence. L'invention concerne en outre des complexes métalliques de ces biphosphites, ainsi que leur utilisation dans des réactions d'hydroformylation.
