Oxidation of Phenols to Quinones by Oxygen Catalysed by a Mixture of Cobalt and Manganese Salts of p-Aminobenzoic Acid Supported on Silica Gel†
Abstract
A mixture of cobalt and manganese salts of p-aminobenzoic acid supported on silica gel catalyses the oxidation of phenols to the corresponding quinones in the presence of oxygen.
