ResumoAbstract The mass spectra of twenty‐eight N ‐substituted 2‐aminobenzoxazoles and 2‐aminobenzothiazoles have been recorded and the identity of various ions in the mass spectra have been established by high resolution measurement. The molecular compound of series, benzoxazole, undergoes loss of hydrogen cyanide and carbon monoxide from the molecular ion as the most important decomposition pathways. The mass spectra of N ‐substituted benzothiazoles showed a similar fragmentation as that of N ‐substituted benzoxazoles.
