The self-chem. ionization in Fourier transform mass spectrometry of 3-benzyloxyaniline (I) and p-bromoaniline (II) is reported. A delay time up to 500 ms at 5 ?10-8 Torr is sufficient to permit ion-mol. reactions to take place. I produced the m/z 290, 380 and 470 ions. II produced the m/z 184 ions. The studies of the reaction mechanisms were performed by multiple resonance ion ejection. In the m/z 290, 380 and 470 ions were obtained by reacting the m/z 91, 290 and 380 ions with neutral mols., resp. II produced the ion m/z 184, which were obtained from the reaction of m/z 92 ions with neutral mols., and most possible structure of ion m/z 184 may be H2NC6H4C6H4NH2.
