Abstract: The present invention relates to a process for preparing a macrocyclic diketone compound of the formula (I), which comprises the oxidation of a bicycloolefine compound of the formula (II) with an oxidizing agent, formulae (I) (II) where in formulae (I) and (II) A is (CH2)n with n being an integer from 2 to 12, where two hydrogen atoms may be replaced by C1-C4-alkyl, in particular methyl, or two hydrogen atoms, which are bound to adjacent carbon atoms may be replaced by a fused 5- or 6-membered saturated carbocycle; B is (CH2)m with m being 1 or 2, where 1 or 2 hydrogen atoms may be replaced by C1-C4-alkyl, in particular methyl.
