The mass spectral fragmentation of N‐arylsulphonyliminopyridinium betaines has been rationalized using high resolution mass spectrometry as well as deuterium labelling. The most characteristic features are a very facile NS bond cleavage and skeletal rearrangements accompanied by the expulsion of SO 2 from the molecular ion and the [M1] ion to the corresponding ionized N‐aryliminopyridinium betaines and azacarbazoles, respectively. The presence of methyl substituents at the α‐position of the pyridine ring has a significant effect on the mode of the fragmentation.
