Notes:
The electron-impact induced fragmentation of twenty 3-alkyl-1-phenyl-Δ2-1,2,4-triazolin-5-ones, three 1-phenyl-1,2,4-triazolin-3,5-diones and ten 2-alkyl-4-phenyloxadiazolin-5-ones has been studied by conventional mass spectrometry. The major cleavages take place in the 1-phenyl-Δ2-1,2,4-triazolin-5-one nucleus, producing three major fragment ions. 4-Phenyloxadiazolin-5-ones exhibit a similar fragmentation pattern to 1-phenyl-Δ2-1,2,4-triazolin-5-ones. Furthermore, several additional fragmentation processes are observed in the case of specific 1,2,4-triasolines.
