“…In the previous decade, we have witnessed a quick and remarkable growth in the use of nanomaterials as catalyst supports. [1][2][3][4] Magnetic nanoparticles (MNPs) have received much attention due to their unique advantages such as a high surface area to bulk ratios, [5] high activity, [6] low toxicity, [7] drug delivery property, [8] biomedical applications, [9][10][11][12] and thermal stability and easy separation. MNPs can be readily separated from a reaction medium using an external magnet, without the need for filtration or centrifugation.…”

In this research project, silica‐modified ZnFe2O4 magnetic nanoparticles were prepared in a simple, short, and straightforward way. Subsequently, an efficient catalyst through immobilization of ascorbic acid on the surface of silica‐coated ZnFe2O4 nanoparticles has been produced. The physical and chemical properties of ZnFe2O4@SiO2‐ascorbic acid were considered by X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Energy‐dispersive X‐ray spectroscopy (EDS), and vibrating sample magnetometer (VSM) analyses. The catalytic activity of described magnetic nanocatalyst was checked out for the synthesis of chromeno[2,3‐d] pyrimidine‐8‐amine and quinazolinone derivatives. The described catalyst was recovered and reused for five continuous cycles without considerable change in its catalytic activity.

Herein joining of poly graphene oxide‐porphyrin to magnetic nanoparticles {poly Fe3O4@SiO2@(CH2)3‐GO‐[PTTA‐NH−Ni] MNPs} was occurred. The synthesized catalyst was characterized by several techniques such as FT‐IR, CHN elemental analysis, EDX, WDX elemental maps, TGA, DTG, DTA, XRD, FE‐SEM, TEM, BET, BJH, VSM, and ICP‐AES. The described magnetic nanoparticles were employed as a benign catalyst for the expedient synthesis of 5‐amino‐7‐aryl‐2‐oxo‐2,3‐dihydrothiazolo[4,5‐b] pyridine‐6‐carbonitriles via anomeric‐based oxidation mechanistic pathway. Target molecules were prepared through a four‐component reaction of 2,4‐thiazolidinedione, aldehydes, malononitrile, and ammonium acetate under solvent‐free conditions at 75 °C. Also, the application of the presented catalyst was investigated under the same reaction conditions for the synthesis of 5,7‐diaryl‐4,7‐dihydro‐[1,2,4]triazolo[1,5‐a]pyrimidines through the three‐component reaction of aldehydes, acetophenones, and 3‐amino‐1,2,4‐triazole.
