MASS SPECTRA OF SOME MONOSUBSTITUTED 1,2-DIAMINOETHANE DERIVATIVES

Abstract

The mass spectra of monosubstituted 1,2-diaminoethane derivatives are studied and compared. The characteristics of the fragmentation of molecular ions (MI) of 1,2-diaminoethane derivatives are shown and discussed. It was established that the direction of the decomposition reaction of MI depends on the nature of the substituents. It was revealed that under conditions of electrons ionization (EI), the α- cleavage with the localization of a positive charge on the nitrogen atom is the most important, which leads to the formation of stable ammonium ions.
