| Abstract: | The electron impact induced fragmentation of chlorine substituted o-aminobenzophenones has been examined. All the compounds show ions formed by α-cleavage on either side of the carbonyl group. The relative intensity of the resulting ions is predictable from the quasi-equilibrium theory. The most important features of the mass spectra of these compounds are, however, intense [M? H]+ ions for the primary amines and [M – OH]+ ions for the N-methylated compounds. These and other less intense peaks as well as some metastable ions allows structural elucidation. |
