Acylation of the title compound with substituted benzoyl chlorides gave the corresponding amides, whereas its reactions with substituted benzoic acids in the presence of POCl3 were accompanied by cyclization with formation of triazolothiadiazoles containing a 1,4-benzodioxane substituent. 4-Amino-5-(1,4-benzodioxan-2-yl)-4H-1,2,4-triazole-3-thiol reacted with substituted benzaldehydes to afford the corresponding
研究了4-氨基-5-(1,4-苯并二恶烷-2-基)-4 H -1,2,4-三唑-3-硫醇的酰化和环化反应。用取代的苯甲酰氯酰化标题化合物得到相应的酰胺,而在POCl 3存在下其与取代的苯甲酸的反应伴随环化并形成含有1,4-苯并二恶烷取代基的三唑并噻二唑。4-氨基-5-(1,4-苯并二恶烷-2-基)-4 H -1,2,4-三唑-3-硫醇与取代的苯甲醛反应生成相应的席夫碱,并用氯乙酸将其烷基化乙醇在乙酸钠存在下得到S-乙氧基羰基甲基衍生物。
