Nickel-Catalyzed Thiolation of Aryl Halides and Heteroaryl Halides through Electrochemistry

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 of an external base at room temperature using undivided electrochemical cells.
