A magnetically separable nanocatalyst prepared by incorporating Pd nanoparticles onto CoFe2O4 magnetic nanoparticles was found to be very effective in catalyzing Sonogashira cross-coupling reactions. In this green synthetic process, it is not necessary to use an external linker to support the palladium nanoparticles onto the cobalt ferrite matrix. The catalyst is effective without the use of any ligand or copper additive. The reaction works smoothly in ethanol at 70 °C with both aryl iodides and bromides to produce corresponding product in high yield. After completion of the reaction, the catalyst could be easily separated using an external magnet and reused up to five catalytic cycles with sustained catalytic activity.
