Electron impact ionization mass spectra of 2-acyloxy-4,6-dimethoxy-l,3,5-triazines were examined. Two general pathways of fragmentation were found: (i) formation of an acylium ion, typical for all the compounds studied, and (ii) rearrangement followed by loss of carbon monoxide, characteristic of de

The mass spectral fragmentations of some 2,3-diaryl-l,3-thiazolidin4ones were established by comparing spectra and by using exact mass measurements. The major fragment ions were identified and their relative importances related to substituent effects and bond strengths. Good correlations were observ
