Application of Fe3O4@SiO2Pr@4-hydroxy-3-methoxybenzaldehyde/bis(thioglycolic acid) as a Green, Efficient, and Magnetically Recoverable Catalyst for the Synthesis of Thiazolidinones

Fe3O4@SiO2Pr@4-hydroxy-3-methoxybenzaldehyde/bis(thioglycolic acid) nanoparticles were prepared and analyzed by FT-IR, VSM, TEM, EDX, and FE-SEM techniques. The synthesized nanoparticles were applied as an efficient and magnetically reusable nanocatalyst for the preparation of various thiazolidinone derivatives under solvent-free condition. The proposed protocol offers many benefits such as productivity, fast reaction, and convenience for work and recovery. The catalyst is reusable for 6 runs by decantation using an efficient magnet without notable loss in activity.
