Unusual expulsion of ‘SO’ was observed from the molecular ions of substituted diphenyldithiocarbonates under electron impact conditions. An initial aryloxy migration to sulphur followed by further rearrangement is proposed for this process, based on the substituent effects. The diarylthioketone radical–cation structure assigned for the [M – SO] ion was confirmed through the collision‐activated dissociation B/E linked‐scan spectra.
