Title: Synthesis and Characterization of 5,5′-[Methanedinitramino-bis(1,2,5-oxadiazol-4,3-diyl)]bis[1H-triazolooxadiazolium]-bis(innersalt)
Abstract: Starting from diaminofurazan(DAF),5,5′-[methanedinitramino-bis(1,2,5-oxadiazol-4,3-diyl)]bis[1H-triazolo-oxadiazolium]-bis(innersalt)(MNOTO) was synthesized by oxidation with Caro′s acid,reduction with Zn dust,cyclization,condensation reaction and nitration with condense nitrate acid/acetic anhydride in 32.7% yield.The structures of intermediates and MNOTO were characterized by elemental analyses,IR and NMR.Condense nitrate acid with acetic anhydride was employed in the nitration of 5,5'-[Methanediamino-bis(1,2,5-oxadiazol-4,3-diyl)]bis[1H-triazolooxadiazolium]-bis(innersalt)(MAOTO).The effects of reaction temperature,reaction time and molar ratio of condense nitrate acid to acetic anhydride on the conversion of MAOTO to MNOTO were studied.The optimal reaction conditions obtained were:reaction temperature,15-20℃;reaction time,5 h;the molar ratio of condense nitrate acid to acetic anhydride,1.5∶1.
