Electrochemical behaviour of NN′-thiobisamines. Cyclic voltammetry in dimethyl sulphoxide with low water content

Abstract

The electrochemical behaviour of NN′-thiobispiperidine and NN′-thiobismorpholine in dimethyl sulphoxide at low water content has been studied by cyclic voltammetry. Electro-oxidation in this medium, producing SO₂ at the electrode surface, parallels the process observed by adding a Brönsted acid in which acid catalysed hydrolysis generates an intermediate species which is followed by a disproportionation process.
