Palibroda N, Cristea C, Silberg IA, et al. 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 beta-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. Rapid Commun Mass Spectrom. 1999;13(21):2227doi: 10.1002/(SICI)1097-0231(19991115)13:21<2227::AID-RCM769>3.0.CO;2-R.
