Negative quasimolecular ions of aromatic carboxylic acid amides have been observed unexpectedly under electrospray ionization conditions. Hypothetically, deprotonation of either carboxamide or carboximidic acid tautomers can produce anions with equivalent resonance structures, the stability of which is affected by conjugated
