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 Á ions is the sulphamide N-S bond cleavage leading to [M Γ€ 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

The electron-impact (EI) and collision-induced dissociation (CID) spectra of the title compounds were studied. The main fragmentation routes of M" ions included losses of hydrocarbon species and the formation of ArCNH' cations. The geometry of ring annelation predictably affected the stabilities of
