Abstract: The mass spectra of a series of dialkyl, alkyl phenyl, and aryl phenyl carbonates have been studied. By a combination of isotope labeling and high-resolution mass spectrometry, the electron impact induced migration of groups other than hydrogen has been uncovered in each class of compound. In the rearrangement step, in each instance, elimination of carbon dioxide occurs with concomitant alkyl or aryl migration. n ...
