Abstract
Unusual expulsion of 'SO' was observed from the molecular ions of subs tituted 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 d iarylthioketone radical-cation structure assigned for the [M - SO] ion was confirmed through the collision-activated dissociation B/E linked -scan spectra.
