Abstract :The mass spectra of phenacylbromide azine (a), p-methyl- (b) and p-chlorophenacylbromideazine (c) were examined and their typical fragmentation patterns were discussed on the basis of the observed fragment ion and meta-stable ion peaks. The mother compounds,(a) - (c), showed the same fragmentation pattern. In the first step of the cleavage of the molecular ions, the elimination of bromine-atom occurred. Evidence for the occurrence of phenyl, methyl and hydrogen rearrangements was already reported by O. Tsuge et al. and S. E. Scheppele et al. But it is interesting that migration of bromine-atom or aryl group do not occur in the fragmentation of the compounds (a) -(c).
