Preparation and explosive properties of azo- and azoxy-furazans

The synthesis and properties of three energetic azo- and azoxyfurazans are described. All are derived from oxidation of 3, 4-diaminofurazan (DAF) (1) and include 3,3′-diamino-4,4′-azoxyfurazan (DAAF) (2), 3,3′-diamino-4,4′-azofurazan (DAAzF) (3) and bis[1, 2, 5] oxadiazolo [3,4-c:3′,4′-g] [1, 2, 5, 6] tetrazocine (DFT) (4). The explosive performance properties of DAAF and DAAzF have been investigated.
