My teacher told me we can convert benzene to phenol within a single step using $\ce{V2O5}$/ $O_2$$\ce{O2}$ at 300 ⁰C (not 500 ⁰C). Later I searched for that reaction but I couldn't find it in all over Google except in Allen's Chemistry handbook.
Does that reaction really occur and if it occurs then what is the mechanism of that reaction?
