Abstract Novel family of azoic dyes pyrazolone based were prepared by an efficient and rapid methodology through diazotization reaction of different pyrazolone amine derivatives, in the presence of acidicionicliquid supported on silica-coated magnetite nanoparticles as acidic catalyst at room temperature and under solvent-free conditions. The attractive advantages of the present process include short
