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

Aromatic I3C chemical shifts of 4-and hubstituted pyridine N-oxides in aprotic and protic solvents are reported and discussed. Changes in chemical shifts caused by hydrogen bonding and protonation are much smaller than those induced by a substituent, and are not related to the pK, values of N-oxides
