چکیده مقاله:
In this paper, bi-pyridinium chloride supported on the core-shell mesoporous substrate, Fe۲O۳@MCM was prepared as an organic-inorganic magnet nanocomposite. Characterization of prepared hybrid nanocomposite, Fe۲O۳@MCM-BP, has taken using FT-IR spectroscopy, X-ray diffraction (XRD),Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Thermal gravimetric analysis (TGA), and Vibrational sample magnetometry (VSM) techniques. The efficacy of the nanocomposite as an alkaline heterogeneous magnetic catalyst in the one-pot multicomponent condensation reaction for preparation of various derivatives of pyrano [C-۲,۳] pyrazole under solvent-free conditions was investigated. High efficiency, ease of manufacture and reusability are some the features of this catalyst.
