The reactivity of 3,4-diamino-1,2,5-oxadiazole () toward nucleophilic substitution of 3,6-bis(3,5-dimethylpyrazol-1yl)-1,2,4,5-tetrazine () was studied. A new class of high nitrogen heterocyclic systems was prepared. It was determined that 3,4-diamino-1,2,5-oxadiazole did not display the required nucleophilicity to be reactive. However, the anion of 3,4-diamino-1,2,5-oxadiazole, prepared by treatment
的反应性 3,4-二氨基-1,2,5-恶二唑()朝向亲核取代的3,6-双(3,5-二甲基吡唑-1基)-1,2,4,5-四嗪()进行了研究。制备了一类新的高氮杂环系统。已确定3,4-二氨基-1,2,5-恶二唑未显示出反应性所需的亲核性。然而,通过用强碱处理制备的3,4-二氨基-1,2,5-恶二唑的阴离子具有足够的反应性以充当亲核试剂。J.杂环化学,(2009)。
