Abstract

An efficient room temperature catalyzed oxidation of cyclohexane to cyclohexanone (K) and cyclohexanol (A) was achieved over hetero-mixed tungsten-vanadia (WO₃/V₂O₅) using H ₂O₂ oxidant. WO₃/V₂O₅ exhibited high catalytic activity to initiate the free-radical oxyfunctionalization of cyclohexane to afford up to 90% conversions within 6 h. The KA selectivity was found to depend on reaction time and the amount of catalyst. The WO₃/V₂O₅ catalyst was highly recyclable with consistent catalytic activity.
