A novel catalyst using Pd supported on bisindolyl functionalized Fe3O4 is synthesized.
The catalyst was characterized using different analytical methods.
The catalyst was applied for Sonogashira reactions of aryl halides (Cl, Br, I) under air.
The Sonogashira reaction was performed under Copper and Phosphane free conditions.
The catalyst was successfully recycled for seven consecutive runs by an external magnet.
