    Description / Table of Contents: The mass spectra of 1,2,4-imidazo[1,5-b]triazepinones and imidazo[4,5-b]pyridinones, formed by condensation of diaminoimidazoles with β-dicarbonyl compounds, are reported and analysed. The main fragmentation pathways have been determined and the utility is shown in structure determinations of isomeric compounds.
    Notes: Les spectres de masse des deux séries d'imidazo[1,5-b]triazépinones-1,2,4 et d'imidazo[4,5-b]pyridinones, obtenues par condensation de diamino-1,5 imidazoles avec un dérivé β-dicarbonylé, sont décrits et analysés. Les principales fragmentations sont données et leur utilité à la détermination de structures des composés isomères est montrée.
