Abstract

Abstract Electron impact mass spectra of 3, 5, 7-trisubstituted 4H-1, 2-diazepines indicate that aryl substituents lead to N 2 expulsion while alkyl substitutents do not. A common fragmentation pattern is observed and discussed for all alkyldiazepines, most of which are newly reported compounds. Assignments are based on electron impact mass spectra of deuteriated substrates and high resolution mass spectra. A previous interpretation of N 2 ...
