The new α ,α ′‐diimine ligands with benzimidazole moiety were synthesized based on the rearrangement of 3‐aroylquinoxalin‐2(1H )‐ones when exposed to 4,5‐diamino‐2,1,3‐benzoxadiazole, 4,5‐diamino‐2,1,3‐benzothiadiazole and 5,6‐diaminoquinoxaline. Among them, we report the first examples of the new heterocyclic system namely benzo[4′,5′]imidazo[1′,2′:1,2]quinolino[3,4‐b and 4,3‐b ][1,2,5]oxadiazolo[3
当3,aroylquinoxalin-2(1 H)-ones重暴露于4,5- diamino-2,1,3-3-benzoxadiazole ,4,5时,基于苯并咪唑部分的新α,α′-二亚胺配体合成-二氨基-2,1,3-苯并噻二唑和5,6-二氨基喹喔啉。其中,我们报告了新的杂环系统的第一个例子,即苯并[4',5']咪唑[1',2':1,2]喹啉[3,4- b和4,3- b ] [1 ,2,5]恶二唑并[3,4- f ]喹喔啉,具有有趣的电化学行为。所有化合物均通过IR,1 H和13 C NMR光谱以及质谱进行了充分表征。
