Iron(iii)-mediated photocatalytic selective substitution of aryl bromine by chlorine with high chloride utilization efficiency†
Abstract
An iron(III)-mediated photocatalytic method for the conversion of aryl, heteroaryl and polycyclic aromatic bromides to the corresponding chlorides with high selectivity has been achieved successfully. The mild reaction conditions and high chloride utilization efficiency promise a bright future for chlorination reactions.
