The electrochemistry-promoted chlorination and bromination of electron-deficient C[sbnd]H bonds was developed, using quinones, coumarins, quinoxalines and 1,3-diketones. This protocol features readily available and safe halogen sources (hydrochloric acid and KBr), high site-selectivity and mild reaction conditions. It could provide an efficient access to a series of chlorinated and brominated quinones, coumarins, quinoxalines and 1,3-diketones.
