Polyvinyl mercaptan, oxidation

These proposals appear to be internally consistent and to explain many experimental observations. Thus, for example, Kolkoff et al. [141,142] and Gorin and Godwin [143] report that ferricyanide may catalyse thiol oxidation either with or without displacement of one CN ligand by a thiol ligand. Overberger et al. [144] also postulate the formation of a ferric—thiol complex during the oxidation of polyvinyl mercaptan by ferric sulphate in dimethyl sulphoxide solution.
