Abstract: In a process for producing hydroperoxides, an alkylaromatic compound of general formula (I): in which R1 and R2 each independently represents hydrogen or an alkyl group having from 1 to 4 carbon atoms, provided that R1 and R2 may be joined to form a cyclic group having from 4 to 10 carbon atoms, said cyclic group being optionally substituted, and R3 represents hydrogen, one or more alkyl groups having from 1 to 4 carbon atoms or a cyclohexyl group, is contacted with oxygen in the presence of a catalyst comprising a polyoxometalate to produce a hydroperoxide of general formula (II): in which R1, R2 and R3 have the same meaning as in formula (I) and wherein the polyoxometalate comprises a polyoxotungstate substituted with at least one further transition metal.
