Studied on Complex Arylhydrazones, Part XI: Electron Impact Studied on Some Diethyl Mesoxalate Phenylhydrazones

Abstract

The potential use of the technique of mass spectrometry as a tool to elucidate the hydrazono structure of diethyl mesoxalate phenylhydrazones has been discussed in this communication. The possibility of their rearrangement to theazo form in the mass spectrometer inlet system at the probe condition has also been examined. Base peak formation by electron impact on diethyl mesoxalate phenylhydrazones was greatly influenced by the nature of substituents in the aromatic nucleus.
