Electron ionization mass spectrometry of difurfuryl diamines

Abstract

Electron impact mass spectrometry (ei-ms) has aided the structural characterization of a novel series of synthetic difuranic diamines and permitted the comparison with a previous study employing electrospray ionization mass spectrometry. As expected, the molecular radical ion was inexistant in this series of compounds and the fragmentation routes of the molecular radical ion were governed either by homolytic cleavage of the radical R_2• or by heterolytic loss of NH₃ to give their respective base peaks.
