摘要
The Pd-Fe-Co-Ni/Fe3O4@Si-NH2 and Pd-Fe-Co-Ni/Fe3O4@Si-NH2@Pd hybrid materials have been synthesized based on magnetite modified with 3-aminopropyltriethoxysilane (APTES). Due to the synergistic effect, new magnetic polymetallic composites have exhibited high catalytic activity in the Sonogashira reaction in a ionic liquid medium, which makes it possible to perform catalysis efficiently in the presence of 0.5 mol % of palladium. The new catalysts can be easily removed from the reaction mixture using an external magnet and can be used up to 5-6 times without any visible loss of activity.
