Abstract: Abstract The efficient synthesis of bispyrazole derivatives was reported in the presence of Fe3O4@SiO2@Si-Pr-NH-(CH2)2-NH2 as a nanomagnetic catalyst in solvent-free conditions. The UV–Vis spectroscopy study of 4,4'-((3-nitrophenyl)methylene)bis(3-methyl-1H-pyrazol-5-ol) derivative 6a was demonstrated that it could be… read more here.
