Magnetic Fe₃O₄@BTC nanocomposite for ultrasound-assisted synthesis of dihydropyrano[2,3-<i>c</i>]pyrazoles.

ABSTRACT: We report an efficient approach for the synthesis of medicinally important dihydropyrano[2,3-c]pyrazoles derivatives by using Fe₃O₄@BTC nanocomposite (NCs) based catalytic system. The Fe₃O₄@BTC NCs were successfully synthesised via. immobilizing benzene-1,3,5-tricarboxylic acid (BTC) on Fe₃O₄ magnetic nanoparticles (MNPs). The synthesised NCs were characterized using X-ray diffraction (XRD) which disclose the formation of a crystalline structure of Fe₃O₄@BTC NCs, Fourier transform infrared (FTIR) spectroscopy suggests the presence of Fe-O band at 576 cm^-1 in addition to -C[double bond, length as m-dash]O, -O-H stretching frequencies are also observed, field emission scanning ele
