Abstract | : | The mass spectra of 5,5-Bis(ethoxycarbonyl)-5,6-dihydro-3,7-diaryl-4H-diazepines were examined, and their typical fragmentation paterns were discussed on the basis of the observed fragment ion and meta-stable ion peaks. In the first step of cleavage of the molecular ions, the elimination of aromatic nitrile or nitrogene occurred. |
