Full TextAbstract
Copper complex‐functionalized magnetic core–shell nanoparticles (Fe3O4@SiO2‐Lig‐Cu) were prepared and characterized using various techniques. The activity of the new catalyst was tested for the Beckmann rearrangement. The reaction conditions allow for the conversion of a wide variety of aldoximes, including aromatic and heterocyclic ones, to amides in good to excellent yields. High efficiency, mild reaction conditions, easy work‐up, use of poly(ethylene glycol) as a green medium and simple purification of products are important advantages of this system. Moreover, the eco‐friendly heterogeneous nanocatalyst could be easily recovered from the reaction mixture using an external magnet and reused several times.
