New direct hydroxylation of benzene with oxygen in the presence of hydrogen over bifunctional ion-exchange resins.
Benzene was hydroxylated directly to phenol with oxygen in the presence of hydrogen over Pt/Pd containing acid resins such as Amberlyst and Nafion/silica composites; over the latter materials the best results were obtained.
