New heterocyclic system — Bis[1,2,3-benzotriazolo[5,6-b;5′,6′-k]]-18-crown-6

It was shown that 1,2,3-triazole derivatives are formed in the reaction of tetra-nitrodibenzo-18-crown-6 with excess hydrazine or ethylhydrazine in DMSO, while the reaction with phenylhydrazine leads to isomeric products of nucleophilic substitution of the nitro group.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 256–257, February, 1988.
