✦ Synopsis

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 derivative 15 in 58% yield.
