Use of organic rhenium compounds in the oxidation of multiple C-C bonds, oxidation processses based thereon and novel organic rhenium compounds

摘要

Compounds of the formula (R¹¹Re) kOlR¹²m · Ln (III), in which R¹¹ is a hydrocarbon group which is bonded to the metal rhenium via a carbon atom to which at least one hydrogen atom is bonded, R¹² is an aliphatic hydrocarbon radical which may contain silicon bridge atoms, or an unsubstituted or substituted phenyl radical, L is a ligand which is bonded to the rhenium metal via one to three O and / or N atoms, and the indices k 1 or 2, l are an integer from 1 to 3 · k, m zero or an integer from 1 to 2 · k and n an integer from 1 to 3 · k and in which the indices k, l, m and n are chosen such that their combination of the 5-, 6- or 7-valency of the rhenium. The invention also relates to compounds of the formula (polymer) for (CH3ReO3) g (VI) in which the rhenium compound CH3ReO3 is bonded to the polymer via amine or amide nitrogen. It also relates to the use of compounds of the formula R¹aRebOc (I), wherein a is 1 to 6, b is 1 to 4 and c is 1 to 14 and the sum of a, b and c is such that it is the 5 to The 7-valence of the rhenium is met with the proviso that c is not greater than 3xb, and in which R¹ represents an optionally fluorine-substituted hydrocarbon radical, or of compounds of the formula (R¹¹Re) kOlR¹²m · Ln (III) or (polymer ) f · (CH3ReO3) g (VI) as catalysts for the oxidation of CC multiple bonds and on such processes.
