Abstract
The invention relates to the bisphosphites of the general formula(I), wherein R1, R2, R3, $4 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.dbd.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, aromatic, aliphatic-aromatic hydrocarbon group with 1 to 50 carbons 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 each other. The invention further relates to the metal complexes of said bisphosphites and to the use thereof in hydroformylation reactions.
