Oxidation of alpha-pinene to verbenone using silica-titania co-gel catalyst
alpha-pinene can be oxidised to verbenone with ca. 60% selectivity using a commercial silica-titania co-gel catalyst with tert-butyl hydroperoxide as oxidant. Using cyclohexene as a model reagent, it is suggested that the formation of verbenone is probably via the formation of a hydroperoxy intermediate.
