Oxygen transfers to both the acetylenic carbons and sulphur are noticed in parallel fragmentation pathways during the electron-impact induced decompositions of Znitrophenylphenyletbynylsulphides. Single oxygen transfer to acetylinic carbons leads to the most abundant ion corresponding to the benzoyl

Fragment ions arising as a result of oxygen transfers from the nitro group to sulphur have been noticed in N-aryl-Znitrobenzenesulphenamides and phenyl-2-nitrophenyl disulphide. In the case of the former a double oxygen transfer to the sulphur has been noticed in the molecular ion whilst a single ox

Double oxygen migration to sulphur from the ortho-nitro group leading to eliminations of SO2 and 'S02H from the molecular ions and single oxygen transfer to the olefinic double bond in the sidechain giving rise to the most abundant ion at m/z 138 have been observed in 2-nitrophenyl styryl sulphides
