One-pot green synthesis of dihydropyrano[3,2-c]chromane derivatives using magnetic nanocatalyst Fe3O4@SiO2@Im-Fc

چکیده مقاله

In this study, we developed and synthesized Fe3O4@SiO2@Im-Fc, a silica-coated Fe3O4 nanoparticle supported by a ferrocene-containing ligand, as a new and efficient nanomagnetic catalyst for the three-component synthesis of dihydropyrano[3,2-c]chromenes in water. All prepared nanoparticles (NPs) were characterized using FT-IR, FE-SEM, XRD, TEM, TGA, and EDX spectroscopic techniques.
