The rearrangement of 5-amino-1-aryl-1,2,3-triazole-4-carbothioamides was investigated. The process was optimized by varying the solvent, temperature, and the type of base. The optimal reaction conditions were found, and new 1-unsubstituted 5-arylamino-1,2,3-triazole-4-carbothioamides were synthesized. It has been shown that 1-aryl-1,2,3-triazoles containing a nitro group in the para position undergo
研究了5-氨基-1-芳基-1,2,3-三唑-4-碳硫代酰胺的重排。通过改变溶剂,温度和碱的种类来优化工艺。找到了最佳的反应条件,并合成了新的1-未取代的5-芳基氨基-1,2,3-三唑-4-碳硫代酰胺。已经显示,在不存在碱的情况下,在正丁醇中加热回流后,在对位含有硝基的1-芳基-1,2,3-三唑发生重排。芳基部分中含有卤素,氢,甲基或甲氧基的化合物的重排需要使用碱。所得化合物的结构通过NMR光谱法和质谱法的数据确认。
