Abstract

Fast Palladium-catalyzed aminations of aryl bromides have been conducted in a non-inert reaction medium with temperature-controlled microwave heating. With a reaction time of 4 minutes at 130 °C or 180 °C, both electron-rich and electron-deficient aryl bromides reacted with various amines to provide fair to good yields of the corresponding secondary and tertiary anilines. As an example the amination of 4-bromobenzonitrile with imidazole is presented.
