The photoinitiated oxidation of benzaldehyde is catalyzed by traces of transition metal ions. The photocatalytic effects of transition metals are explained in terms of the formation of their unstable oxidation states which act as catalysts of the thermal oxidation. The reaction catalyzed by Fe(II) and Fe(III) ions is discussed in detail.
