An iodine-mediated method for the synthesis of 6-alkylthio-1,3,5-triazine-2,4-diamines by the reaction of N-alkylpyridinium salts and NH4SCN in air is reported. Twenty-seven compounds were obtained under the standard conditions. Pyridinium salts work as benzyl-group transfer reagents to promote the formation of the CBn–SSCN bond and thereby the construction of the triazine skeleton. A plausible mechanism
报道了一种通过N-烷基吡啶鎓盐与NH 4 SCN在空气中反应合成6-烷硫基-1,3,5-三嗪-2,4-二胺的碘介导方法。在标准条件下获得了27种化合物。吡啶盐作为苄基转移试剂,促进 C Bn –S SCN键的形成,从而构建三嗪骨架。根据实验结果和文献调查,提出了一种合理的机制。
