Notizen:
The McLafferty rearrangements in the mass spectra of butyrophenone, l-phenyl-2-pentanone, l-phenyl-3-hexanone, 4-phenyl-4-methyl-2-pentanone, 2-butyronaphthone and 2-butyryl-anthracene are compared with photochemical Norrish Type II reactivity. As a rule, the McLafferty process occurs in these compounds even when the Norrish Type II process does not; the simple analogy of production of similar reactivities by the removal of an electron (in the McLafferty rearrangement) and the promotion of an electron to a non-interacting orbital (in the Norrish Type II process) should thereforebe viewed as complicated by the intervention of electronically excited molecular ions in which the McLafferty process can occur.
