A series of macrocycles containing four furazan rings bonded by three azo bonds 2, 5 and 7 have been synthesized from the common precursor, 3-amino-3′-nitro(azofurazan) 3. The macrocycles closure is a result of NN bond formation at oxidative cyclization of corresponding bis(3-aminofurazan-4-yl) precursors. X-Ray crystal structures of macrocycles 2, 2•AcOH, 11 and 13 are reported.
从常见的前体3-氨基-3'-硝基(氮杂呋喃)3合成了一系列包含四个由三个偶氮键2、5和7键合的呋喃环的大环。大环的封闭是在相应的双(3-氨基呋喃-4-基)前体的氧化环化作用下形成N N键的结果。报道了大环2、2 •AcOH,11和13的X射线晶体结构。
