✦ Synopsis

Interesting oxygen transfers from the o-nitro group to allenic carbons were observed in allenyl o-nitrophenyl sulphides under electron impact conditions giving rise to abundant fragment ions at m/z 151,138 and 136. However, a similar oxygen transfer to the sulphur leads to another intense ion at m/z 145. The proposed fragmentation pathways and the ion structures were established through high-resolution data, collision-activated dissociation massanalysed ion kinetic energy and B/E linked-scan spectra.

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
