Transition‐metal‐catalyzed coupling reactions are useful tools for synthesizing aryl sulfur compounds. However, conventional transition‐metal‐catalyzed thiolation of aryl bromides and chlorides typically requires the use of strong base under elevated reaction temperature. Herein, we report the first examples of nickel‐catalyzed electrochemical thiolation of aryl bromides and chlorides in the absence
过渡金属催化的偶联反应是合成芳基硫化合物的有用工具。但是,常规的过渡金属催化的芳基溴化物和氯化物的硫醇化反应通常需要在升高的反应温度下使用强碱。在此,我们报道了在室温下使用不分隔的电化学电池,在不存在外部碱的情况下,镍催化的芳基溴化物和氯化物的电化学催化硫醇化反应的第一个实例。
