  • Patent number: 7145041
    Abstract: The invention relates to a method for catalytically oxidizing unsaturated hydrocarbons to form oxidation products, and to the production of saturated alcohols, ketones, aldehydes or carboxylic acids by subsequently hydrogenating the oxidation product. A compound of formula (I) is used as a catalyst during oxidizing in which: R1, R2=H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 carbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 signify identical or different radicals or R1 and R2 can be coupled to one another via a covalent bond, with Q1, Q2=the same or different, C, CH, N; X, Z=C, S or CH2; Y=O or OH; k=0, 1 or 2; 1=0, 1 or 2; m=1 to 100 in the presence of a radical initiator. Peroxy compounds or azo compounds can be used as radical initiators. Preferred substrates are cyclic aliphatic or aromatic compounds.
