Fragmentation pathways of the title compounds under electron impact were compared to those of their (1aryl)substituted analogs reported earlier. The main fragmentation route of the M ร ions is the sulphamide N-S bond cleavage leading to [M ร ArSO 2 ] ions. No loss of the alkyl substituents from the
Fragmentation pathways of the title compounds were studied using accurate mass measurements and collision-induced dissociation spectra. Substituents in the ortho position of the aryl group at the pyrimidine ring were found to play a special role in the electron impact (EI) induced fragmentation of t
