The modes of fragmentation of perchlorylbenzene (C6H6C10s) and its perdeutero derivative under electron impact are reported and discussed. The occurrence of the [C,H,O]and [C,H,O]+ ions is accounted for in terms of a novel phenyl migration from chlorine to oxygen.

Abstract
The fragmentation of 4‐styrylquinoline (I), 4‐(p‐nitrostyryl)‐quinoline (II), 4‐(p‐chlorostyryl)‐quinoline (III), 4‐(p‐hydroxystyryl)‐quinoline (IV), 4‐(p‐methoxystyryl)‐quinoline (V), 4‐(p‐dimethylaminostyryl)‐quinoline (VI) and 4‐(p‐cyanostyryl)‐quinoline (VII) under electron‐impact in the mass spectrometer is reported. The role and the influence of substituents on the fragmentation scheme is discussed. The loss of the substituents from the molecular ion is correlated with LCAOMO quantities.
