  (α-Fe2O3)-MCM-41 as a magnetically recoverable nanocatalyst for the synthesis of pyrazolo[4,3-c]pyridines at room temperature

  摘要：

  MCM-41 embedded magnetic nanoparticles which was prepared through the formation of MCM-41 in the presence of Fe3O4 nanoparticles has been used as a magnetically recoverable catalyst for the synthesis of new series of pyrazolo[3,4-c]pyridine derivatives. This catalyst with 10 wt.% of loaded iron oxide nanoparticles was highly recyclable (up to 5 times), and was easily recovered from the reaction mixture using an external magnet without loss of activity. The prepared magnetic catalyst is characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), nitrogen physisorption measurements, and acid-base titration.
