The oxygenation of 1,5-dihydroxynaphthalene (1) and 2,6-di-t-butylphenol (4) with Co-salen as a catalyst has been examined.The activation of oxygen in these reactions is different.From reactions with specific quenchers and the measurement of ultraweak chemiluminescence it is concluded that, depending on the nature of the substrate, Co-salen activates oxygen in the singlet state or in the radical state.This behavior must be considered when cobalt complexes are investigated as model substances of enzymatic oxygenation reactions.
