A novel one‐pot synthesis of 3‐amino‐1,2,4‐triazole developed via iron (III) catalyzed route is reported. The new method is more efficient, simple, and convenient and presents a concise new strategy for the synthesis of 3‐amino‐1,2,4‐triazole derivatives. The iron (III) complex intermediate assisted in the intramolecular bond cyclization owing to its Lewis acidity or oxidizing properties. A series
据报道,通过铁(III)催化途径开发的一种新型一锅法合成3-氨基1,2,4-三唑。该新方法更加高效,简单和方便,为合成3‐氨基1,2,4‐三唑衍生物提出了一种简洁的新策略。铁(III)配合物中间体由于其路易斯酸度或氧化特性而有助于分子内键的环化。还研究了一系列在对位和/或邻位带有取代的给电子和吸电子基团的芳族腈。取代基的位置影响最终化合物的收率,对位取代的底物收率相对较高。
