Notes:
The mass spectra of some alkyl, aryl and acyl benzotriazoles are reported and discussed on the basis of their thermolytic and photolytic fragmentation products. All benzotriazoles so far studied lose a molecule of nitrogen to give the intermediate radical cations upon electron-impact. Subsequently cyclization and a hydrogen migration lead them to the molecular ions of thermolytic and photolytic fragmentation products. A general rule for predicting the possibility of 1-3 hydrogen migration, based on a knowledge of the electronic state of the radical cation is proposed.
