Abstract
Phosphites of the formula I or II and their metal complexes, their preparation and the use of the phosphites as ligands in catalytic reactions, in particular in processes for the hydroformylation of olefins, are described.
Claims30
A phosphite of the formula I,
- where R1, R2, R3 and R4 are each independently a monovalent substituted or unsubstituted aliphatic, alicyclic, aromatic, heteroaromatic, mixed aliphatic-alicyclic, mixed aliphatic-aromatic, heterocyclic, mixed aliphatic-heterocyclic hydrocarbon radical having from 1 to 50 carbon atoms, H, F, Cl, Br, I, —CF3, —CH2(CF2)jCF3 where j=0–9, —OR9, —COR9, —CO2R9, —CO2M, —SR9, —SO2R9, —SO3R9, —SO3M, —SO2NR9R10, —NR9R10, or —N═CR9R10, where R9 and R10 are independently a H, monovalent substituted or unsubstituted aliphatic and aromatic hydrocarbon radical having from 1 to 25 carbon atoms and M is an alkali metal ion, an alkaline earth metal ion, an ammonium ion or a phosphonium ion,
- or adjacent radicals R1 to R4 together form a fused substituted or unsubstituted aromatic, heteroaromatic, aliphatic, mixed aromatic-aliphatic or mixed heteroaromatic-aliphatic ring system;
- Q is a k-valent substituted or unsubstituted aliphatic, alicyclic, mixed aliphatic-alicyclic, aromatic, heteroaromatic, or mixed aliphatic-aromatic hydrocarbon radical having from 1 to 50 carbon atoms, where aliphatic parts of Q may contain one or more of oxygen, sulfur or nitrogen,
- k is at least 2 and R1, R2, R3 and R4 in the individual structural elements bound to Q can be different from one another.

A phosphite of the formula II,
- where R1, R2, R3 and R4 are each independently a monovalent substituted or unsubstituted aliphatic, alicyclic, aromatic, heteroatomic, mixed aliphatic-alicyclic, mixed aliphatic-aromatic, heterocyclic, mixed aliphatic-heterocyclic hydrocarbon radical having from 1 to 50 carbon atoms, H, F, Cl, Br, I, —CF3, —CH2(CF2)jCF3 where j=0–9, —OR9, —COR9, —CO2R9, —CO2M, —SR9, —SO2R9, —SO3R9, —SO3M, —SO2NR9R10, —NR9R10, or —N═CR9R10, where R9 and R10 are independently a H, monovalent substituted or unsubstituted aliphatic and aromatic hydrocarbon radical having from 1 to 25 carbon atoms and M is an alkali metal ion, an alkaline earth metal ion, an ammonium ion or a phosphonium ion,
- or adjacent radicals R1 to R4 together form a fused substituted or unsubstituted aromatic, heteroaromatic, aliphatic, mixed aromatic-aliphatic or mixed heteroaromatic-aliphatic ring system;
- Q is a k-valent substituted or unsubstituted aliphatic, alicyclic, mixed aliphatic-alicyclic, heterocyclic, aromatic, heteroaromatic, or mixed aliphatic-aromatic hydrocarbon radical having from 1 to 50 carbon atoms, where aliphatic parts of Q may contain one or more of oxygen, sulfur or nitrogen,
- k is at least 2 and R1, R2, R3 and R4 in the individual structural elements bound to Q can be different from one another.
