Tetraethyldiethylenetriamine tribromide magnetic nanoparticles (MNPs-TEDETA tribromide) are synthesised and characterized as an efficient, new, metal free and magnetically reusable nanocatalyst for the synthesis of 2,3-dihydroquinazolin-4(1H)-one and polyhydroquinoline derivatives. The synthesized catalyst was characterized using FT-IR, TGA, XRD, EDX, VSM and SEM analyses
