Synthesis of trisfurazanylamine derivatives

The reactions of the 4H,8H-bisfurazano[3,4-b;3’,4’-e]pyrazine dianion with fluorofurazans 6 and 9 yielded tris(4-R-furazanyl)-amine derivatives; a macrocycle incorporating the tertiary amine moiety was synthesised by oxidative cyclization of a linear precursor with terminal amino groups by dibromoisocyanurate.
