✦ Synopsis

A first study of the fragmentation of aromatic N-oxides upon electron impact was made by Bryce and Maxwell in 1965 (1) and they reported that the presence of M-16 peaks was diagnostic for these N-oxides. However, Grigg and Ode11 (2) observed the decrease of the M-16 peak and the appearance of an M-17 peak in the mass spectra of 2-alkyl substituted pyridine N-oxides, and argued that the M-16 peak was not always characteristic for this type of compound. In continuation of our studies on the mass spectrometry of nitrogen-containing aromatic compounds, the mass spectra of benzimidaeole-(A) and quinoxaline-(B and C) N-oxides have been examined for the presence of M-16 or M-17 peaks. O-* Part VII: A.Tatematsu, B7, 1226 (1966).
