Ortho effects in organic molecules on electron impact: 21—Oxygen transfers from the ortho nitro group to sulphur in N†aryl†2†nitrobenzenesulphenamides and phenyl†2†nitrophenyl disulphide

Fragment ions arising as a result of oxygen transfers from the nitro group to sulphur have been noticed in N‐aryl‐2‐nitrobenzenesulpbenamides 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 oxygen transfer to the β‐sulphur atom and a double oxygen transfer to the α‐sulphur atom have been observed in the latter. The proposed fragmentations are confirmed by high‐resolution data, B/E linked‐scan spectra and chemical substitution. Copyright © 1989 John Wiley & Sons, Ltd.
