The new heteroaromatic compounds, dipyridotetraazapentalenes 3–5, were synthesized in two steps from readily available triazolopyridines 6 and 10. N-Arylation of 6 and 10 followed by subsequent reductive cyclization of the N-(nitropyridyl)-triazolopyridines with triethylphosphite in toluene afforded 3, 4 and 5, respectively, in good yields. Nitration of 3 afforded the new energetic tetranitrotetraazapentalene
新的杂芳族化合物,二吡咯并四氮杂戊烯酮3–5,是从容易获得的三唑并吡啶6和10分两步合成的。Ñ的-Arylation 6和10随后的后续还原环化ñ - (硝基吡啶基)-triazolopyridines与亚磷酸三乙酯在甲苯中,得到3,4和5,分别在良好的产率。硝化3得到新的高能四硝基四氮杂戊烯衍生物15,产率为58%。
