Abstract: Procedimiento para la oxidación catalítica de hidrocarburos saturados o insaturados, sustituidos o no sustituidos, heterociclos, alcoholes, éteres, cetonas, aldehídos, aminas u hollín (sustrato), para obtener hidroperóxido, alcohol, cetona, ácido carboxílico o ácido dicarboxílico correspondientes, caracterizado porque como catalizador se usa un compuesto de fórmula I con R1, R2 = H, resto alcoxi, resto carboxilo, resto alcoxicarbonilo o resto hidrocarburo alifáticos o aromáticos, respectivamente con 1 a 20 átomos de carbono, SO3H, NH2, OH, F, Cl, Br, I y/o NO2, en la que R1 y R2 designan restos idénticos o diferentes, o R1 Y R2 pueden estar unidos entre sí mediante un enlace covalente Q1, Q2 = C, CH, N, CR5, respectivamente de manera igual o diferente X, Z = C, S, CH2, respectivamente de manera igual o diferente Y = O, OH K = 0, 1, 2 L = 0, 1, 2 m = 1 a 3; R5 = uno de los significados de R1 en presencia de un iniciador por radicales, encontrándose la relación molar del catalizador respecto al hidrocarburo entre 10-6% en moles a 2, 5% en moles.

Abstract: The invention relates to a process for preparing phenol derivatives by catalytic oxidation of an aromatic hydrocarbon to the hydroperoxide and subsequent cleavage of the hydroperoxide to give the phenol derivative and a ketone, wherein a compound of the formula I where R1, R2=H, aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, in each case having from 1 to 20 carbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, where R1 and R2 are identical or different radicals or R1 and R2 may be joined to one another via a covalent bond, and X, Z=C, S, CH2 Y=O, OH k=0, 1, 2 l=0, 1, 2 m=1-3; is used as oxidation catalyst in the presence of a free-radical initiator, where the molar ratio of the catalyst to the aromatic hydrocarbon is less than 10 mol %.
