Based on the organocatalytic reaction of enamine azide addition of 2,4,6-triazido-1,3,5-triazine to acetylacetone acetoacetic ester, we synthesized a series of previously unknown mono-, di-, and tri(1,2,3-triazolyl)-substituted-1,3,5-triazines that additionally carried carbonyl, ester, and azide groups. The structure of the obtained compounds was proved by NMR (1H, 13C) and IR spectroscopy, and the composition was confirmed by elemental analysis. With the aid of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) coupled to mass spectrometry (TG-MS), we obtained data on the thermal behavior and decomposition mechanism for these compounds. We demonstrated that di(1,2,3-triazolyl)-substituted 1,3,5-triazines have an increased thermal stability and have higher values of decomposition onset temperature (220–250 °C) in comparison with tri(1,2,3-triazolyl)-substituted 1,3,5-triazines (180 °C and 160 °C, respectively).

具有羰基、酯和叠氮化物官能团的1,2,3-三唑基取代的1,3,5-三嗪的合成、表征和热分解性能

基于2,4,6-三叠氮基-1,3,5-三嗪与叠氮烯胺加成到乙酰丙酮乙酰乙酸酯的有机催化反应,我们合成了一系列以前未知的单、二和三(1,2, 3-三唑基)-取代的-1,3,5-三嗪还带有羰基、酯和叠氮基团。通过NMR( 1 H, 13 C)和IR光谱证实了所得化合物的结构,并通过元素分析确认了组成。借助差示扫描量热法 (DSC) 和热重分析 (TGA) 与质谱 (TG-MS) 相结合,我们获得了这些化合物的热行为和分解机制的数据。我们证明,与三(1,2)取代的1,3,5-三嗪相比,二(1,2,3-三唑基)取代的1,3,5-三嗪具有更高的热稳定性,并且具有更高的分解起始温度(220–250 °C) ,3-三唑基)取代的 1,3,5-三嗪(分别为 180 °C 和 160 °C)。
