Synthesis of multiple quinoline derivatives using novel ionic liquid-based nano-magnetic catalyst (MNPs@SiO2-Pr-AP-tribromide)

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