    摘要： The invention relates to the use of compounds of the formula R1aRebOc.Ld  (I), in which and the total of a, b and c is such as to comply with the pentavalency or heptavalency of rhenium, with the proviso that c is not larger than 3×b, and in which R1 is absent or identical or different, and is an aliphatic hydrocarbon radical having 1 to 10 carbon atoms, an aromatic hydrocarbon radical having 6 to 10 carbon atoms or an arylalkyl radical having 7 to 9 carbon atoms, it being possible for the R1 radicals where appropriate to be substituted identically or differently, independently of one another, as catalysts for oxidizing electron-rich aromatic compounds and their derivatives, the catalysts being employed in a peroxide-containing solution in the presence of an anhydride of a carboxylic acid and/or of a dehydrating agent.
