7 H -三呋咱并[3,4- b :3',4'- f :3",4"- d ]氮杂环庚三烯及衍生物的合成与表征

Using 3,4-bis(4'-aminofurazano-3'-yl)furazan (BATF) as the starting material, 3,4-bis(4'-nitrofurazano-3'-yl)- fura- zan (BNTF) was synthesized by Caro's acid oxidation with a yield of 93%. Based on the reactivity of NO2 in BNTF, two en- ergetic material 7H-trifurazano(3,4-b:3',4'-f:3'',4''-d)azepine (HTFZA) and 7-aminotrifurazano(3,4-b:3',4'-f:3'',4''-d)azepine (ATFAZ) were designed and synthesized from BNTF and NH3•H2O or NH2NH2•H2O via the nucleophilic substitution and cyclization, then HTFAZ was nitrated in the system of HNO3-Ac2O to firstly obtain a novel compound 7,7'-bis(terfurazan (3,4-b:3,4'-d:3'',4''-f)azepine) (BTFZ). The above three compounds were characterized by the means of IR, 1 H NMR, 13 C NMR, MS and elemental analysis. The single crystal of HTFAZ was studied by X-ray single crystal diffraction. Its crystal belongs to orthorhombic, space group is P2(1)/n with a=0.7252(15) nm, b=0.6458(14) nm, c=1.6814(4) nm, V=0.7781(3) nm 3 , Z=4,
