Systematic studies on the behavior of 1,4,2-dithiazolium cations (1) toward various amino compounds (ammonia, aliphatic and aromatic amines, hydrazine, semicarbazide, thiosemicarbazide derivatives, etc.) were performed. The reaction pathway could be classified into three types depending on possible three fission modes of the initially-formed adduct. The main products were 5-imino-1,4,2-dithiazole,
对 1,4,2-二噻唑鎓阳离子 (1) 对各种氨基化合物(氨、脂肪族和芳香族胺、肼、氨基脲、氨基硫脲衍生物等)的行为进行了系统研究。根据最初形成的加合物可能的三种裂变模式,反应途径可以分为三种类型。主要产品为5-亚氨基-1,4,2-二噻唑、硫脲和1,3,4-噻二唑衍生物,分别通过三种不同的途径。为了阐明控制反应过程的因素,1与对取代苯胺衍生物的反应在系统变化的条件下进行。碱的强度和溶剂的极性对反应性有明显的影响。还讨论了反应机理。
