The mass spectra of a series of benzamides and naphthamides have been investigated with respect to their propensity to lose an aromatic hydrogen atom from their molecular ions. Deuterium labeling and a study of model compounds have led to a plausible mechanistic rationalization for the formation of the [M — 1] ions. The other principal fragmentation processes observed with these compounds are discussed, including the specificity of a previously uninvestigated rearrangement process.
