A series of trihalogenated alkenylbenzenes undergo consecutive palladium catalyzed inter- and intramolecular amination reactions to deliver a series of 1-functionalized mono-chloroindoles. 4-, 5-, 6- and 7-Chloroindoles can all be prepared: carbamates, anilines and amines can be employed as the N-nucleophile.
