of pyridinium salts, which occur with good results in less delocalized electronic systems, do not take place when applied to the above obtained pyrylium salts. Therefore, as starting material 4-(azulen-1-yl)-1-(n-butyl)-2,6-dimethylpyridinium perchlorate was used, which was condensed with heteroarylcarboxaldehydes. These compounds were completely characterized and some of their spectra were discussed
合成了吡啶鎓和吡啶鎓盐和吡啶,吡啶在第4位具有氮杂-1-基部分,在位置2和6具有两个2-杂芳基乙烯基。从吡喃酮开始获得吡啶盐,并且可以通过用乙酸铵处理由这些盐制备吡啶。当将吡啶鎓盐用于上面获得的吡啶鎓盐时,不会发生合成吡啶鎓盐的一般程序,该程序在较少离域的电子系统中会产生良好的结果。因此,使用4-(azulen-1-yl)-1-(n-丁基)-2,6-二甲基吡啶高氯酸盐作为起始原料,将其与杂芳基甲醛缩合。这些化合物已被完全表征,并讨论了一些光谱。揭示了它们与某些金属离子的相互作用,观察亲和力比简单的azulenepyridines更好。在本文的最后部分,提供了几种吡啶盐和吡啶的氧化还原电势,与未乙烯基化衍生物的氧化还原电势相比。
