Substituent effects on the mass spectra of substituted phenyl acetates

Abstract
The mass spectra of a series of meta‐ and para‐substituted phenyl acetates have been examined. Substituent effects have been correlated with Δ (AP‐IP) values and by using the Harrison and Chin approach. The bond‐cleavage and rearrangement reactions of phenyl accetates are compared with the corresponding reactions of acetanilides and the differences attributed to the degree of transmission of polar effects in the two systems.
