Protonated molecules of 2,5-di-R1,R2-substituted-1,3,4-oxadiazoles lose isocyanic acid (loss of mass 43) via skeletal rearrangement. This was observed in low-energy CID mass spectra recorded by using electrospray ionisation (ESI). On electron ionisation induced decomposition these compounds also reveal complex skeletal rearrangement, consisting on N2 and CO elimination, leading to the formation of fluorene or indene type ions. It was found that abundances of fragment ions formed in these processes are in good agreement with their theoretically calculated stabilities. In the case of ESI use the fragment ion abundances were calculated in relation to [M+H]+ ion abundances and for EI use, where extensive fragmentations proceed, the sums of the abundances of [M-N2-CO]+. ions and abundances of fragment ions derived from them, were expressed as a percentage of total-ion current.

This survey covers the mass spectrometic properties of organosulfur compounds containing the sulfide, disulfide, and sulfone functional groups. Attention is paid to the uni‐ and biomolecular chemistry of both positive and negative ions, as well as to the reactions of ions, with sulfur containing species, in the gas phase. The role of other functional groups on the decomposition of organic S, SO, SO2 containing gaseous ions is also discussed. The selection of sulfur containing compounds includes many naturally occurring and pharmaceutically significant products, that will be presented in the following order: alkaloids, amino acids, peptides, proteins, carbohydrates, steroids, and metabolites. © 1996 John Wiley & Sons, Inc.
