The use of a magnetically recoverable palladium nanocatalyst supported on a green biochar enables an efficient palladium-catalyzed tandem reaction for the one-pot synthesis of 9H-carbazoles from inexpensive anilines and 1,2-dihaloarenes under microwave irradiation. The method shows a drastic reduction in reaction times and excellent compatibility with different functional groups.
