Definitions
- the present invention relates to compounds which selectively catalyze the epoxidation of olefins with atmospheric oxygen, a process for their preparation and a process for the preparation of epoxides by catalytic oxidation of olefins with air or oxygen.
- Epoxies such as ethylene oxide, propylene oxide, 1, 2-butene oxide or similar epoxides, are common intermediates in the manufacture of a large number of products.
- the oxirane function in such compounds is very reactive, with ring-opening reactions taking place with nucleophilic reactants.
- epoxides can be hydrolyzed to glycols, which as
- Polyether polyols produced by ring opening polymerization of epoxides, are commonly used as intermediates in the production of polyurethane foams, elastomers, coatings, sealants or similar articles.
- glycol ethers e.g. B. find use as a polar solvent.
- Many different processes have been developed for the production of epoxides which are to selectively catalyze the epoxidation of alkenes.
- Huybrecht J. Mol. Catal. 71, 129 (1992); EP-A-311 983 describes the epoxidation of olefins with hydrogen peroxide in the presence of titanium silicate compounds as a catalyst.
- the range of products obtained in the oxidation of alkenes with titanium silicate catalysts is, however, insufficiently controllable, so that even minimal changes in the reaction conditions or the reactants used lead to drastic changes in the proportions of the end products.
- the actual active catalyst is a molybdenum complex that has already added TBHP and one equivalent of epoxy.
- the process proceeds with high selectivity, but an expensive oxidation agent is used. There are also problems with the Reproducibility on what prevents a technical use of the process.
- Norbornene is converted to the 2,3-epoxy norboman in 85% yield.
- 56% of styrene is epoxidized and converted to benzaldehyde in 39% yield.
- cyclohexene is converted to the corresponding ketone without formation of epoxide (J.Chem. Soc. Dalton Trans. 1990, 3735).
- Epoxidation-active transition metal salts or complexes of molybdenum are used as catalysts, e.g. Chlorine, carbonyl or chloronitrosyl complexes that still contain donor ligands such as hexamethylphosphoric triamide (HMPT), triphenylphosphite or acetonitrile.
- HMPT hexamethylphosphoric triamide
- the most active compounds here are those that contain HMPT as donor ligands, with HMPT being known as a carcinogen.
- the aim of the present invention is to provide compounds which are able to catalyze the epoxidation of olefins selectively and in good yields, using only atmospheric oxygen as the oxidizing agent.
- the invention further relates to a process which allows olefins to be oxidized with oxygen or air with high selectivities to the corresponding epoxides.
- Another object of the invention is therefore to provide catalysts which catalyze the epoxidation of olefins selectively and in good yields, in which the expensive metal content is reduced by application to a support material.
- the present invention thus relates to compounds of the general formula (1)
- M represents molybdenum, ruthenium or vanadium and L represents an N, O or S donor ligand.
- the index x is an integer from 1 to 3, preferably 1 to 2, y is an integer from 1 to 2x + 1, preferably y is 1 or 2, where y is chosen such that due to the sum of x + z one
- Metal oxidation level of + 5 (vanadium) or + 6 (molybdenum, ruthenium) results.
- oxidizing agent hydrogen peroxide or another hydroperoxide, e.g. tert-butyl peroxide, or other commonly used oxidizing agents.
- hydrogen peroxide or another hydroperoxide e.g. tert-butyl peroxide, or other commonly used oxidizing agents.
- tert-butyl peroxide e.g. tert-butyl peroxide
- only air or oxygen is used.
- the ligand is bound in a bidentate fashion to the metal center, which can bind up to two such ligands.
- the dioxo complexes can be present here both as ice and as trans isomers.
- the vanadium and molybdenum complexes are in the form of cis isomers and the ruthenium complexes are in the form of trans isomers.
- R 1 or R 2 can also represent a hydrogen residue.
- the ring can optionally be substituted with alkyl, aryl or alkox ⁇ groups.
