Studt on the Synthesis of 3,3-Dinitroazetidine and 1,1′-Bis-(3,3-dinitro- azetidin-1-yl)methane

3 ,3 二硝基氮杂环丁烷 (DNAZ)的含能盐及衍生物是一类重要的高能量密度材料 ,因此DNAZ的合成和应用受到了密切关注 .采用新的合成方法 ,以 1 叔丁基 3 ,3 二硝基氮杂环丁烷为起始原料 ,以 76.3 %的总收率得到了DNAZ ,然后以DNAZ为原料 ,与多聚甲醛反应 ,得到了 1,1′ 亚甲基 -双 ( 3 ,3 二硝基 1 氮杂环丁烷 ) (DNAZ CH2 DNAZ) .用红外和核磁共振光谱等对各化合物的结构进行了表征 .

Because the energetic salts and derivatives of 3,3-dinitroazetidine (DNAZ) are a new kind of important high density energetic materials, the synthesis and applications of DNAZ have attracted much attention. In this paper DNAZ was synthesized in 76.3% overall yield starting from 1-tert-butyl-3,3-dinitro-azetidine. In addition, DNAZ reacted with paraformaldehyde giving 1,1'-bis-(3,3-dinitro-azetidin-1-yl) methane (DNAZ-CH2-DNAZ). The structures of these compounds were confirmed by IR, H-1 NMR and C-13 NMR spectra.
