4-amino-3-mercapto-1,2,4-triazole derivatives in ethanol in the presence of TEA, novel bis(5,6-dihydro-s-triazolo[3,4-b]thiadiazines) linked to diphenyl ether moiety were obtained in good yields. Moreover, by reacting bis(2-bromoethanone) with the appropriate pyridinethiones in ethanolic sodium ethoxide at reflux, good yields of bis(thienopyridines) linked to diphenyl ether moiety were obtained. The structures
摘要 在几滴 TEA 存在下,适当的 α-卤代酮或 α-酮基亚肼酰氯与相应的双(肼甲硫代酰胺)在回流下在乙醇中反应产生了与二苯醚连接的新型双噻唑作为新型杂化物的良好产率分子。此外,通过 1,1'-(oxybis(4,1-phenylene))bis(2-bromoethanone) 与适当的硫代酰胺反应,以高产率获得了一些新型双噻唑。此外,通过双 (2-溴乙酮) 与适当的 4-amino-3-mercapto-1,2,4-triazole 衍生物在 TEA 存在下在乙醇中反应,新型双 (5,6-二氢- s -triazolo [ 3,4-乙]噻二嗪)连接到二苯醚部分以良好的产率获得。此外,通过使双(2-溴乙酮)与适当的吡啶硫酮在乙醇钠中回流反应,获得了与二苯醚部分连接的双(噻吩并吡啶)的良好收率。使用元素和光谱数据确认新化合物的结构。
