Synthesis, Characterization, and Application of CoFe2O4@TRIS@sulfated Boric Acid Nanocatalyst for the Synthesis of 2-Amino-3-cyanopyridine Derivatives

The aim of this research is the synthesis of a novel acidic nanocatalyst using the layer-by-layer assembly technique. The CoFe2O4@TRIS@sulfated boric acid nanoparticles were easily synthesized and studied as a highly beneficial, recyclable, and magnetite nanocatalyst for the synthesis of 2-amino-3-cyanopyridine derivatives. The chemical structure of CoFe2O4@TRIS @sulfated boric acid nanocatalyst was completely confirmed with different techniques like FESEM, Map, EDS, XRD, TGA/DTG, VSM, and FT-IR analyses. Briefly, the newly synthesized nanocatalyst offers some advantages such as simplicity of work-up, highly stable, environmental friendliness, reusability, excellent yields, and short reaction time.
