摘要

The invention relates to the bisphosphites of the general formula(I), wherein R<1>, R<2>, R<3>, R<4>, R<5>, R<6> 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, -OR<7>, -COR<7> -CO2R<7>, -CO2M, -SR<7>, -SO2R<7>, -SOR<7>, -SO3R<7>, -SO3M, -SO2NR<7>R<8>, NR<7>R<8>, N=CR<7>R<8>, NH2, wherein R<1> to R<6> are the same or different and can be covalently linked with each other, R<7>, R<8> 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.
