AbstractDouble oxygen migration to sulphur from the ortho‐nitro group leading to eliminations of SO2 and ·SO2H from the molecular ions and single oxygen transfer to the olefinic double bond in the side‐chain giving rise to the most abundant ion at m/z 138 have been observed in 2‐nitrophenyl styryl sulphides on electron impact. The proposed fragmentation mechanisms and the product ion structures were confirmed with the aid of high‐resolution data, B/E linked scan and CID spectra.
