Abstract (en)

[origin: DE19717176A1] The invention relates to the use of compounds of formula (I): R<1>aRebOc. Ld as catalysts for the oxidation of aromatic compounds rich in electrons and of derivatives of such compounds, whereby the catalysts are used in a solution containing peroxide and in the presence of an anhydride, a carboxylic acid and/or a dehydrating agent. In said formula (I) a = 0 or an integer between 0 and 6, b = an integer between 1 and 4, c = an integer between 1 and 12, d = an integer between 0 and 4, and L = Lewis base. The sum of a, b and c is such that it ensures the pentavalence or heptavalence of the rhenium, provided that c is not greater than 3 . b. R<1> can either not be present, or represent the same group or represent a different group and is an aliphatic hydrocarbon rest having between 1 and 10 C-atoms, an aromatic hydrocarbon rest having between 6 and 10 C-atoms or an aryl alkyl rest having between 7 and 9 C-atoms, whereby said R<1> rests independently of each other may possibly be substituted identically or differently.
