Abstract

An efficient, transition metal catalyst-free amination of aryl halides under microwave irradiation is a particularly powerful method for the coupling of electron-rich aryl halides with various amines. Meta-substituted anilines have been prepared from ortho- or para-substituted phenylhalides. A mechanism via a benzyne intermediate has been proposed.
