In the electron impact mass spectra of N,N′-diaryl-1,3-phenylenediamines, recorded under conditions generating the molecular ion as a base peak, the most important step involve a β-aromatic cleavage with H rearrangement, leading to the expulsion of a neutral arylamine; this fact can be used in meta isomer identification since for the corresponding 1,2- and 1,4-isomers the expulsion of an aryl radical is a competitive process
