Electron impact studies. XXXI. Skeletal-rearrangement fragments in the mass spectra of anils

Abstract

Skeletal-rearrangement fragments are observed in the mass spectra of all anils derived from aromatic aldehydes. The rearrangement processes have been studied by high-resolution mass spectrometry and in certain cases by deuterium labelling. All processes are of the general type [ABC]⁺ → [AC]⁺ +B.
