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.
The Chlorination of 2-t-Butyl-4,6-dimethylphenol and 2,6-Di-t-butyl-4-methylphenyl. The Formation of 5,6-Dichloro-4-methylenecyclohex-2-enones

The chlorination in acetic acid of 2-t-butyl-4,6-dimethylphenyl (1) gives two chloromethylene compounds (4) and (5), and trichloro ketones (6) and (7).In contrast, 2,6-di-t-butyl-4-methylphenol (2) gives six chlorination products (14)-(19).The notable fea
