5-Amino-4-aminomethyl-1-aryl-v-triazolines are synthesized by treating aryl azides with acrylaldehyde and secondary amines. The triazolines readily react with strong bases yielding the corresponding triazoles. Acids act differently, depending on the kind of the amine residues. When these are strongly basic (aliphatic) the triazoline ring is cleaved with nitrogen evolution. Among the degradation products
5-氨基-4-氨基甲基-1-芳基- v -triazolines通过用丙烯醛和仲胺处理芳基叠氮化合成。三唑啉易于与强碱反应,生成相应的三唑。酸的作用取决于胺残基的种类。当这些是强碱性(脂肪族)时,三唑啉环会随着氮的释放而断裂。在降解产物中,鉴定出丙烷-1,2-二酮。当胺残基是碱性较弱的(芳族)环未被切割并且两个相应的1-芳基- v -triazoles和4-氨基甲基-1-芳基- v获得-triazoles。讨论了这些反应的机理。
