The reactions of (aryl)(chloro)methyl p-tolyl sulfoxides 2 with tetrasulfur tetranitride (S4N4) in p-dioxane at reflux gave 3,5-diaryl-1,2,4,6-thiatriazine 1-oxides, 3,5-diaryl-1,2,4-thiadiazoles, and 1-amino-3,5-diaryl-1,2,4,6-thiatriazine 1-oxides. For the first time, the structures of 3,5-diaryl-1,2,4,6-thiatriazine 1-oxides were unequivocally characterized based on X-ray crystallography of 3,5-di(3
(芳基)(氯)甲基对甲苯基亚砜2与四氮化四硫(S 4 N 4)在对二恶烷中的回流反应,得到3,5-二芳基-1,2,4,6-噻三嗪1-氧化物, 3,5-二芳基-1,2,4-噻二唑和1-氨基-3,5-二芳基-1,2,4,6-噻三嗪1-氧化物。首次基于3,5-二(3,4-二甲基苯基)-1的X射线晶体学对3,5-二芳基-1,2,4,6-噻三嗪1-氧化物的结构进行了明确表征,2,4,6-噻三嗪1-氧化物。所述thiatriazine 1-氧化物用的治疗米-CPBA得到2,6-二芳基-4-(3-氯苯基)-1,3,5-三嗪。提出了形成噻三嗪1-氧化物和1,3,5-三嗪的机理。
