The mass spectra of a series of mefa-and para-substituted phenyl acetates have been examined. Substituent effects have been correlated with A(AP-IP) values and by using the Harrison and Chin approach. The bond-cleavage and rearrangement reactions of phenyl acetates are compared with the correspondin
## Abstract Substited pivalanilides give rise to fragments corresponding to anilies on electronβimpact, which is due to the migration of a hydrogen atom from the __t__βbutyl group to the nitrogen. The Hammett correlation indicates that the formation of this fragment is favoured by electronβdonating
