One-Pot Synthesis of 1,4-Dihydropyridine Derivatives Catalyzed by Silica-Coated Magnetic NiFe2O4 Nanoparticles-Supported H14[NaP5W30O110]

Аннотация

Silica-coated magnetic NiFe₂O₄ nanoparticles-supported H₁₄[NaP₅W₃₀O₁₁₀] (NiFe₂O₄@SiO₂-H₁₄[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.
