Mass spectra of o‐aminobenzophenones

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 imp...
