文摘
- •
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.
