Reactions between 4-amino-1,2,4-triazole and nitro-substituted benzaldehydes in acetonitrile under neutral conditions afford stable hemiaminals, seven of which have been structurally and spectroscopically characterized. Two Schiff bases have also been obtained after the addition of hydrochloric acid to the reaction mixture. We describe a correlation between the conformation and configuration of the hemiaminals, and conclude that the formation of these species is determined by the substituents on the phenyl ring, as well as by the presence of 4-amino-1,2,4-triazole.
在中性条件下,4-氨基-1,2,4-三唑与硝基取代的苯甲醛在乙腈中发生反应,生成了稳定的半二胺,其中七种半二胺的结构和光谱特征已经确定。在反应混合物中加入盐酸后,还得到了两个希夫碱。我们描述了半二元化合物的构象和构型之间的相关性,并得出结论:这些物质的形成是由苯环上的取代基以及 4-氨基-1,2,4-三唑的存在决定的。
