A comparative study on the catalytic activity of Fe3O4@SiO2–SO3H and Fe3O4@SiO2–NH2 nanoparticles for the synthesis of spiro [chromeno [2, 3-c] pyrazole-4, 3′-indoline

Abstract: Sulfuric acid and (3-aminopropyl)-triethoxysilane were successfully attached to the core–shell structure of Fe3O4@SiO2 nanoparticles separately. The prepared nanoparticles were characterized by vibrating sample m
