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. Springer Science+Business Media B.V. 2011.
