Amine functionalized magnetic resorcinol formaldehyde as a green and reusable nanocatalyst for the Knoevenagel condensation.

ABSTRACT: Herein, a novel amine-functionalized magnetic resorcinol-formaldehyde with a core-shell structure (Fe₃O₄@RF/Pr-NH₂) is prepared through the chemical immobilization of (3-aminopropyl)trimethoxysilane over Fe₃O₄@RF composite. Characterization through FT-IR, EDX, PXRD, and TGA confirmed successful surface modification while preserving the crystalline structure of Fe₃O₄. The VSM analysis demonstrated excellent superparamagnetic properties, and SEM and TEM images revealed spherical particles for the designed nanocatalyst. The Fe₃O₄@RF/Pr-NH₂ nanocomposite was employed as a robust nanocatalyst to promote the Knoevenagel condensation of benzaldehydes with ethyl cyanoacetate and malononitr
