1H, 13C and 15N Nuclear Magnetic Resonance Analysis of 3,3’,4,4’-Diaminoazoxyfurazan Obtained by Oxidation of 3,4-Diaminofurazan with Peroxyformic Acid

The aim of this study was an extensive NMR analysis of 3,3’,4,4’-diaminoazoxyfurazan (DAAF) obtained by a new method that involves oxidation of 3,4-diaminofurazan to DAAF using a H2O2/HCOOH mixture. The raw product, after washing with water and drying, was min. 98% pure. We present proton, carbon and nitrogen NMR spectra of the prepared DAAF. Detailed analysis of the nitrogen spectrum gave interesting information about aromaticity of the substituted furazan rings.
