The combination of small organic molecule and base serves as a unique system for the activation carbon-halogen bonds in haloarenes by single electron transfer(SET).[1] However,most molecules employed as promoters only allow for the activation of aryl iodides,and efficient activation of aryl bromides and chlorides using this mode is still rather challenging.
