Recently, magnetic iron oxide nanoparticles functionalized with various organic groups increasing attention in the synthesis of the organic compounds. In this study, ionic liquid nano-magnetic pyridinium-tribromide (MNPs@SiO2-Pr-AP-tribromide) as a new nanocatalyst was synthesized. The structure of the catalyst was identified by FT-IR, TGA, XRD, FE-SEM, EDX, EDS, TEM and VSM analysis. The nanocatalyst was efficient for the synthesis of quinoline derivatives through the one-pot reaction of 2-amino-5-chlorobenzophenone and pentane-2,4-dione. The advantages of this catalyst are easy preparation, large surface area, renewability, high thermal stability, high activity, shortening reaction time, improving efficiency, easy purification, and mild reaction conditions.
