The oxidation of the bridging sulfur atom in diphenyl sulfides, leading to the formation of sulfoxides and sulfones, was investigated.The various rearrangement processes which occur in substituted 2,4-dinitrophenyl phenyl sulfoxides during electron impact and lead to the appearance of characteristic fragment ions were demonstrated.The effect of the nature of substituents on the main directions in mass-spectrometric dissociation was investigated, and a correlation was obtained between log Z'/Z for the fragment due to elimination of the bridging SO group from the molecular ion and the Hammett ? constants.
