Hypohalites as reagents for the macrocyclization of diamines of the furazan series

The possibility of using hypohalites for the oxidative cyclocondensation of diamines was demonstrated for the first time by the example of 3,4-diaminofurazan and 4,4’-diamino-3,3’-azofurazan and the series of macrocyclic polydiazenofurazans, including previously unknown difurazano[c,g]-l,2,5,6-tetrazocine, was synthesized.
