The effect of temperature on singlet substrate oxidations by dioxygen has been examined for both non-catalyzed reactions and reactions catalyzed by transition metal ions. The kinetics are discussed for various activation energies of catalyzed and non-catalyzed reactions and for various catalyst concentrations. It is shown that at sufficiently high temperatures trace amounts of transition metal ions present in reaction systems as impurities may become effective in catalyzing singlet substrate oxidations.
