Synthesis of variously 5-substituted-4-carbaldehyde-1,2,3-triazole derivatives 2 was accomplished by reacting sodium azide with α,β-acetylenic aldehydes 1 in DMSO at room temperature. Therefore, the reaction remains basic avoiding the generation of the hazardous explosive HN3, resulting in a safe process. This mild and general reaction was instantaneous and was essentially quantitative.
通过使叠氮化钠与α,β-炔醛1在室温下于DMSO中反应,完成了各种5-取代的4-甲醛-1,2,3-三唑衍生物2的合成。因此,该反应仍然是基本的,避免了危险爆炸物HN 3的产生,从而确保了安全的过程。这种轻微和一般的反应是瞬时的,基本上是定量的。
