説明

<jats:title>Abstract</jats:title><jats:p>Bis(salicylidene)ethylenediiminocobalt(II) (salcomine)* is a homogeneous catalyst for the oxidation of phenols with molecular oxygen in solutions of chloroform or methanol at room temperature. A number of substituted phenols with a free<jats:italic>para</jats:italic>‐position have been studied; in most cases the corresponding<jats:italic>para</jats:italic>‐benzoquinone was the main reaction product. Compounds originating from coupling of aryloxy radicals were also detected or isolated. Some speculations on the mechanism of the reaction have been made.</jats:p>
