Abstract In this work, we synthesized a heterogeneous magnetic nanocatalyst using iron oxide (Fe 3 O 4 ) surface‐modified with L‐arginine@NiO @L‐Arg@NiO). Several characterization techniques such as fourier transform infrared (FT‐IR), field emission scanning electron microscopy (FE‐SEM), X‐ray diffraction (XRD), high‐resolution transmission (HR‐TEM), dispersion spectra (EDS) and thermogravimetric analysis (TGA) were used to extensively analyze its structural morphological properties. The Fe @L‐Arg@NiO was subjected the one‐pot multi‐component synthesis of 3,4‐dihydropyrimidin‐2‐(1 H )‐ones derivatives under solvent‐free conditions. It determined that demonstrating desired product 85%–95% yield, in shorter reaction time. Furthermore, simple work‐up, reusability catalyst up five cycles sustainability are characteristic features environment friendly protocol.

Abstract The production of 1‐(4‐chlorophenyl)‐1 H ‐pyrazol‐3‐ol by oxidizing 1‐(4‐chlorophenyl)‐ pyrazolidin‐3‐one with 2 O suffers from some shortcomings. oxidation 1‐(4‐chlorophenyl)‐pyrazolidin‐3‐one to can be realized air catalyzed Co(II)@AC (prepared supporting cobalt(II) on activated carbon). Air is a good substitute for because it minimize the cost, hazards, and pollution, which beneficial improvement process pyraclostrobin. In this study, carbon has been modified C 4 solution improve catalytic performance Co(II)@AC. experiments indicate that best made heating at 300 °C 3 h rate 5 °C/min in N after being soaked 0.4 mol/L 50 12 an L/S ratio 40/1 mL/g. concentration obtained immobilized optimized 39.39% over loaded original carbon. Characterization results reveal modification increases specific surface area enhances acidity surface. primarily determined physical structure. selectivity toward mainly influenced chemical characteristics.
