An efficient electrochemical methylthiolation reaction of imidazo[1,2-a]pyridines was achieved. The method used DMSO as both the methylthiolating reagent and solvent and KI as both the hydrogen atom transfer reagent and supporting electrolyte. The reaction was performed under transition metal- and chemical oxidant-free conditions. For various substituted 2-arylimidazo[1,2-a]pyridines, C-3 methylthiolation
实现了咪唑并[1,2- a ]吡啶的高效电化学甲硫基化反应。该方法使用DMSO作为甲硫基化试剂和溶剂,KI作为氢原子转移试剂和支持电解质。该反应在无过渡金属和化学氧化剂的条件下进行。对于各种取代的2-芳基咪唑并[1,2- a ]吡啶,以良好的产率区域选择性地获得了C-3甲基硫基化产物。
