Oxidative hydroxylation of phosphine in aqueous alcohol solutions of p-benzoquinone

The oxidation of phosphine in aqueous alcohol solution of benzoquinone in the presence of iodide ions is studied. Kinetic measurements, redox potentiometry, and gas chromatography are used to determine the kinetic regularities of the oxidative hydroxylation of phosphine, and a single-stage redox mec...

Summary:The oxidation of phosphine in aqueous alcohol solution of benzoquinone in the presence of iodide ions is studied. Kinetic measurements, redox potentiometry, and gas chromatography are used to determine the kinetic regularities of the oxidative hydroxylation of phosphine, and a single-stage redox mechanism is proposed for this reaction. It is found that the iodine resulting from the oxidation of I − ions by quinone is the reagent responsible for the formation of phosphorus-containing products.
