Abstract (en)
[origin: DE19717181A1] The invention relates to the use of compounds of formula (I): R<1>aRebOc.Ld as catalysts for selectively oxidating olefins by breaking the C-C bond into the corresponding carbonyl compounds in the presence of a compound containing peroxide, whereby the quantitative ratio of olefin to peroxide compound ranges from 1:2 to 1:14. 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 be 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 can independently of each other be substituted identically or differently.
