Dv. Ramana et al., NOVEL ARYLOXY MIGRATIONS IN SUBSTITUTED DIPHENYLDITHIOCARBONATES UNDER ELECTRON-IMPACT CONDITIONS, Organic mass spectrometry, 28(4), 1993, pp. 459-462
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.
