摘要: Synthesis of bis(4-pyridylamino)triazine stabilized on silica-coated nano-Fe3O4 particles, and their feasibility as a reusable heterogeneous basic catalyst are reported. The catalytic performance this novel material was studied for the green synthesis highly functionalized 4H-pyran, 4H-thiopyran 1,4-dihydropyridine derivatives via one-pot multicomponent reactions. Eco-friendly method, high yield purity desired products, short reaction time along with ease workup procedure outline advantages these new methodologies over earlier ones. Surface magnetic properties core–shell hybrid nanoparticles were characterized transmission scanning electron microscopies, X-ray diffraction, energy-dispersive Fourier transform infrared spectroscopies vibrating sample magnetometry.
