Heterocyclic analogs of pleiadiene. 55. 2-Azidoperimidines: Stability of the tetrazole form

2-Azidoperimidine and its 1-methyl, 1-benzyl, and 1-phenyl derivatives were synthesized by the action of sodium azide on the corresponding 2-chloroperimidines. The IR spectra constitute evidence for the existence of all of these compounds in both the solid state and in solution in exclusively the tetrazolo [1,5-a]perimidine form.See [1] for Communication 54.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1114–1117, August, 1981.
