3,4-Bis(4-aminofurazan-3-yl)-furoxan was synthesized by the dimerizaion of 3-amino-4-oxy cyano-furazan. However, 3-amino-4-oxycyanofurazan was not steady and could not be separated, purified and confirmed by spectrum. Therefore, 1,3-dipolar cycloaddition reactions of 3-amino-4-oxycyanofurazan were performed with four different olefins, and four novel compounds were synthesized, which were 3-(4-aminofurazan-3-yl)-5-cyano-Δ2-isoxazoline, 3-(4-aminofurazan-3-yl)-5-acetoxy-Δ2-isoxazoline, 3-(4- aminofurazan-3-yl)-5-butyl-Δ2-isoxazoline and 3-(4-aminofurazan-3-yl)-cyclohexyl-Δ2-isoxazoline. At the same time, 3-amino-4-(N-benzoyloxyaminocarbonyl)-furazan was synthesized by the capture of 3-amino- 4-oxycyanofurazan with benzoyl chloride. The structures of the five novel compounds were confirmed by IR, 1H NMR, 13C NMR, MS techniques and elemental analysis. These studies provided indirect evidences for the presence of 3-amino-4-oxycyanofurazan.
