Hermann, Tobias S.; Klapötke, Thomas M.; Krumm, Burkhard; Stierstorfer, Jörg (2018): Synthesis, Characterization and Properties of Ureido-Furazan Derivatives. In: Journal of Heterocyclic Chemistry, Vol. 55, No. 4: pp. 852-862

The reaction of a variety of amino-furazans with chlorosulfonyl isocyanate was carried out to synthesize ureido-furazans. The nitration to nitro-ureido-furazan was successful in the case of 3-nitro-4nitroureido- furazan and 3,4-dinitroureido-furazan. Furthermore, furazan derivatives linked to a second amino-oxadiazole were synthesized. All compounds were intensively characterized by X-ray diffraction measurements, NMR spectroscopy, vibrational spectroscopy (IR, Raman), BAM sensitivity tests and differential thermal analysis. The energetic properties were calculated using EXPLO5 6.03.
