Evidence is adduced by e.s.r. spectroscopy for the mediation of radical-cations R2S˙S2+˙ during oxidation of a sulphide R2S by the titanium(III)–hydrogen peroxide or –persulphate couple. It is suggested that they arise from a first-formed transient, R2S+˙, which is subject to competing reactions of which one is with a further molecule of sulphide. Other reactions, and the variation of their relative importance with structure, are briefly discussed.
