Abstract:

The catalytic activity of VO(acac)2 for the cyclohexane(Cy) oxidation was studied. The effects of various parameters, such as the amounts of H2O2, HNO3, H2O and Cy were investigated. The highest total turnover number(TON) is 234, which can be increased to 353, 342 and 403, respectively with the adding of o-phthalic, m-phthalic or p-phthalic acid. A reaction mechanism was also supposed primarily.
