SbFX on Nickel Ferrite as an Efficient, Cost-Effective, and Magnetically Recyclable Nanocatalyst for the Knoevenagel Condensation Reaction of Malononitrile and Benzaldehyde Under Green and Mild Conditions

In this article, magnetic nanoparticle (MNP) from-SbFX was synthesized on nickel ferrite as-NiFe2O4@SbFX. Standard methods in catalyst identification, such as FT-IR, SEM, EDX, XRD, VSM, BET and ICP-OES, were used for catalyst identification. The study of the results of the performed analyses shows the correct synthesis, high superparamagnetic properties, crystal structure, high porosity, and a size smaller than 50 nm of the synthesized catalyst. The performance of the-NiFe2O4@ SbFX catalyst in the Knoevenagel condensation reaction of benzylidenemalononitrile (BMN) was investigated, and it was observed in this reaction, aldehyde derivatives are condensed with 2 mmol of malononitrile in the presence of-NiFe2O4@ SbFX paramagnetic nanoparticles in ethanol under reflux conditions with 85-95% efficiency and duration of 50-70 min.
