N-alkylpyridinium salts are versatile pseudohalides for SET-mediated cross couplings. However, the common 2,4,6-triphenylpyridinium salt is plagued by poor atom economy and high cost of synthesis. Thus, there is a growing need for more practical scaffolds and innovative strategies for pyridinium salt formation. Herein, we report the synthesis of benzylic 2,4,6-collidinium salts via electrooxidative
N-烷基吡啶鎓盐是用于 SET 介导的交叉偶联的通用假卤化物。然而,常见的2,4,6-三苯基吡啶鎓盐存在原子经济性差、合成成本高等问题。因此,越来越需要更实用的支架和创新的吡啶盐形成策略。在此,我们报道了通过电氧化 C-H 官能化合成苄基 2,4,6-collidinium 盐。该方法为依赖于预功能化底物的取代和缩合的传统策略提供了一种补充方法。
