通过溴和碘的作用,对4,5-二取代的3-烯丙基硫基-4 H -1,2,4-三唑的亲电子杂环化的区域选择性进行了研究。研究了影响卤化区域选择性的因素,即亲电试剂的性质和高氯酸锂的存在。开发了一种获得5,6-二氢-3 H- [1,3]噻唑并[3,2-b]三唑鎓盐的方法。这些盐的结构通过光谱方法和化学转化得到证实。
Abstract The reactions of [1,3]thiazolo[3,2-b][1,2,4]triazol-7-ium salts with nucleophiles were investigated. Theoretical investigation of reactivity descriptors and structural parameters of [1,3]thiazolo[3,2-b][1,2,4]triazol-7-ium cation was carried out, and the reactivity centers of the model salts were located. An efficient general method for the synthesis of novel poly-functional derivatives of
