Nanop articles hav e recently emerged as efficient he trogeneous nanocatalys ts in the organic synthe sis [۱]. Ho wever, parti cles with di ameters of less than ۱۰ ۰ nm are di fficult to se parate by filtration tech niques. This drawback can be overcome by u sing magn etic nanopar ticles (MNPs), which can be easily removed from the re action mixture by mag netic separation. Magnetic nanoparticles are efficient, readily available, high-su rface-area resulting in high catalyst loading c apacity and outstanding stability heterogeneous supports for catalysts [۲].
