Heck and Sonogashira cross-coupling reactions using recyclable Pd-Fe3O4 heterodimeric nanocrystal catalysts

We have developed a convenient Pd-Fe3O4 heterodimeric nanocrystal catalyst system for Heck and Sonogashira reactions. This catalyst offers an environment-friendly, atom-efficient, and robust catalytic system for both reactions. Furthermore the nanocrystal catalyst could be easily separated by an external magnet and recycled six times without losing its catalytic activity.
