Regiospecific chlorination of aromatic substrates using donor–acceptor and hydrogen bonding interactions
Abstract
The chlorination of aromatic substances has been achieved with good regioselectivity using 2,3,4,4,5,6-hexachlorocyclohexa-2,5-dien-1-one and 2,3,4,5,6,6-hexachlorocyclohexa-2,4-dien-1-one as chlorinating agents.
