Abstract
A method is provided for preparing organic hydroperoxides by oxidizing aryl alkyl hydrocarbons having a benzylic hydrogen with an oxygen containing gas using as a catalyst an oxo (hydroxo) bridged tetranuclear metal complex having a mixed metal core, one metal of the core being a divalent metal selected from Zn, Cu Fe, Co, Ni, Mn or mixtures thereof and another metal being a trivalent metal selected from In, Fe, Mn, Ga, and Al.
Claims8
A method for oxidizing an aryl alkyl hydrocarbon to an organic hydroperoxide comprising:
- contacting an aryl alkyl hydrocarbon having a benzylic hydrogen with an oxygen containing gas and a catalytically effective amount of an oxo(hydroxo) bridged tetranuclear metal complex having a mixed metal core, one metal of the core being a divalent metal selected from Zn, Cu, Fe, Co, Ni, Mn or mixtures thereof and another metal being a trivalent metal selected from In, Fe, Mn, Ga and Al or mixtures thereof.
