    Description / Table of Contents: The mass spectra of 21 1,4-pyrazolo[3,4-b]diazepines are reported and analysed. Each of the five structures of the diazepine ring present is characterized by a particular group of fragmentations; among them one is common to all the compounds under study: the cleavage of C-5—C-6 and C-7—N-8 bonds leading to pyrazoloimidazoles ions.
    Notes: Les spectres de masse de 21 pyrazolo[3,4-b]diazépines-1,4 dans lesquelles le cycle diazépine peut présenter cinq structures différentes, sont décrits et analysis. Chaque structure a été caractérisée par un ensemble original de ruptures. Parmi celles-ci un mode de fragmentation commun à tous les composés étudiés a été identifié: il s'agit de la rupture des liaisons C-5—C-6 et C-7—N-8 avec formation d'ions pyrazoloimidazoles.
