USE OF ORGANIC RHENIUM COMPOUND FOR OXIDATION OF UNSATURATED C-C BOND, OXIDATION BASED ON SAID METHOD AND NEW ORGANIC RHENIUM COMPOUND

摘要

Compounds of the formula (R11Re)kO1R12 mxLn (III) in which R11 is a hydrocarbon group which is bonded to the rhenium via a carbon atom to which at least one hydrogen atom is still attached, R12 is aliphatic hydrocarbon radical which may contain silicon bridge atoms, or is an unsubstituted or substituted phenyl radical, L is a ligand which is bonded to the rhenium metal via one to three oxygen and/or nitrogen atoms, and the index k is 1 or 2, the index 1 is an integer from 1 to three times k, the index m is zero or an integer from 1 to twice k, and the index n is an integer from 1 to three times k, and in which the indices k, l, m and n are selected such that their combination satisfies the 5-, 6- or 7-valence of rhenium. The invention also provides compounds of the formula (polymer)fx(CH3ReO3)8 (VI) in which the rhenium compound CH3ReO3 is bonded to the polymer via amine or amide nitrogen in the polymer. It further provides for the use of compounds of the formula R1aRebOc (I) in which a is 1 to 6, b is 1 to 4 and c is 1 to 14 and the total of a, b and c is such that the 5-valence to 7-valence of rhenium is satisfied, with the proviso that c is not greater than three times b, and in which R1 represents an optionally fluorinated hydrocarbon, or of compounds of the formula (R11Re)kOlR12mxLn (III) or (polymer)fx(CH3ReO3)g (VI), as catalysts for the oxidation of multiple C-C bonds and also provides processes of this type.
