title: Regioselective chlorination and bromination of unprotected anilines under mild conditions using copper halides in ionic liquids.
abstract: By using ionic liquids as solvents, the chlorination or bromination of unprotected anilines at the para-position can be achieved in high yields with copper halides under mild conditions, without the need for potentially hazardous operations such as supplementing oxygen or gaseous HCl.
