A series of aliphatic and aromatic thioethers and dithioethers of s‐triazine were synthesised to study their thermal properties, in particular the thermally induced thiyl radical generation ability. Four symmetric s‐triazine sulfides of the type (RS)3C3N3, namely 2,4,6‐tris(phenylthio)‐ (1), 2,4,6‐tris(para‐tolylthio)‐ (3), 2,4,6‐tris(ethylthio)‐ (5) and 2,4,6‐tris(tert‐butylthio)‐1,3,5‐triazine (7)
合成了一系列的s-三嗪脂族和芳族硫醚和二硫醚,以研究它们的热性能,特别是热诱导的噻吩基自由基的生成能力。(RS)3 C 3 N 3类型的四个对称的S-三嗪硫化物,即2,4,6-三(苯硫基)-(1),2,4,6-三(对甲苯甲硫基)-(3) ,2,4,6-三(乙硫基)-(5)和2,4,6-三(叔丁硫基)-1,3,5-三嗪(7)以及四个对称的S-三嗪二硫化物(RSS)3 C 3 N 3的类型,即2,4,6-tris(phenyldithio)-(2),2,4,6-三(对-甲苯基二硫代)-(4),2,4,6-三-(乙基二硫代)-(6)和2,4,6-三-(叔丁基二硫代)-1,3合成了5-5-三嗪(8)。所有化合物均通过1 H和13 C NMR,红外和拉曼光谱以及元素分析进行了全面表征。的单晶X射线衍射分析1,2和5讨论。通过热重分析,质谱分析(TGA-MS)和量子化学计算研究了热行为。极限氧指数(L
