An efficient and environmentally friendly electrochemical oxidative selective halogenation of pyrazolones has been developed under conditions free of metals, external oxidants, and external supporting electrolytes. The reaction demonstrates good functional group tolerance and maintains high efficiency in large-scale synthesis, yielding moderate to excellent yields of the desired 4-halopyrazolones.
在不含金属、外部氧化剂和外部支持电解质的条件下,开发了一种高效且环保的吡唑啉酮电化学氧化选择性卤化方法。该反应表现出良好的官能团耐受性,并在大规模合成中保持高效率,产生中等至优异的所需4-卤代吡唑啉酮产率。该方法为将卤素部分直接安装到生物活性吡唑啉酮衍生物中提供了一条绿色便捷的途径,可用于多种应用。
