Characterization of prepared hybrid nanocomposite, Fe2O3@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-2,3] pyrazole under solvent-free conditions was investigated. High efficiency, ease of manufacture and reusability are some the features of this catalyst.
