benzene + H2O2
-
Cyclocybe aegerita phenol + H2O oxygenation of the unactivated aromatic ring of benzene with hydrogen peroxide as co-substrate. Reaction proceeds via an initial epoxide intermediate that re-aromatizes in aqueous solution to form phenol. Second and third [per]oxygenation is also observed and results in the formation of further hydroxylation and following [per]oxidation products hydroquinone and p-benzoquinone, catechol and o-benzoquinone as well as 1,2,4-trihydroxybenzene and hydroxy-p-benzoquinone, respectively. The origin of the oxygen atom incorporated into benzene or phenol is the peroxide ?
