Electron impact mass spectrometry of some 3-[3-(4-aryl)-1,2,4-oxadiazole-5-yl] acyl arylaldehyde hydrazone derivatives

Abstract

This report describes the results of a study of the electron impact mass spectrometry behaviour of 20 new compounds of a series of 3-[3-(4-aryl)-1,2,4-oxadiazole-5-yl] acyl arylaldehyde hydrazone derivatives. The most relevant possible fragmentation patterns of this class of compounds under electron impact are outlined.
