Synthesis and Characterization of Azofurazan and Azoxyfurazan

3,3’-Diamino-4,4’-azofurazan(DAAF) was synthesized by using the oxidant NaClO from the start material 3,4-diaminofurazan(DAF).3,3’-Diamino-4,4’-azoxyfurazan(DAOAF) can be obtained by using OXONETM as a stronger oxidant than NaClO from DAF.Then,DAAF was nitrated with 100% nitric acid to generate 3,3’-dinitramino-4,4’-azofurazan(DNAAF).3,3’-Diazido-4,4’-azofurazan(DADAF) and 3-amino-3’-azido-4,4’-azoxyfurazan(AAAF) were prepared from diazonium salt of DAAF and DAOAF respectively by treatment with sodium azide.After storing for several days at room temperature,DADAF was transformed to 5-[4-azido-furazan]-5H-triazo1ofurazan(I) easily.These compounds were characterized by 1H NMR,13C NMR,IR and MS.Their TG and DSC curves were also analyzed.
