Iron-oxide nanoparticles mediated cyclization of 3-(4-chlorophenyl)-1-hydrazinylisoquinoline to 1-(4,5-dihydropyrazol-1-yl)isoquinolines
Iron-oxide nanoparticles were obtained using chitosan templates and their crystalline character and particle size have been confirmed through powder x-ray diffraction and transmission electron microscopy measurements. The particle sizes were found to be 10–25 nm. The diversified chalcones 2 were rea...

| description | Iron-oxide nanoparticles were obtained using chitosan templates and their crystalline character and particle size have been confirmed through powder x-ray diffraction and transmission electron microscopy measurements. The particle sizes were found to be 10–25 nm. The diversified chalcones 2 were reacted with 1-hydrazinylisoquinoline 1 in the presence of iron-oxide nanoparticles to the corresponding pyrazolines 3a–j in high yield and purity. The pyrazolines were characterized by spectroscopic techniques. |
