One-Pot Synthesis of 1,4-Dihydropyridine Derivatives Catalyzed by Silica-Coated Magnetic NiFe2O4 Nanoparticles-Supported H-14[NaP5W30O110]

摘要

Silica-coated magnetic NiFe2O4 nanoparticles-supported H-14[NaP5W30O110] (NiFe2O4@SiO2-H-14[NaP5W30O110]) was successfully synthesized and shown to be a versatile and highly efficient heterogeneous catalyst for one-pot multicomponent synthesis of 1,4-dihydropyridine derivatives under solvent-free condition. The synthesized catalyst can be magnetically recovered and reused four times without significant loss in catalytic efficiency.
