Abstract

See full text

A method and composition are disclosed for the oxidation of aromatic substrates in the presence of oxygen, a catalyst, a proton source, and a non-gaseous reductant. In a preferred embodiment, benzene is oxidized to phenol in the presence of oxygen, a vanadyl catalyst, trifluoroacetic acid as a proton source, and ferrocene as a reductant. The method is economical, safe, and amenable to commercial scale-up.
