Ligand complex of copper (II) supported on superparamagnetic Fe₃O₄@SiO₂ nanoparticles: an efficient and magnetically separable catalyst for N-arylation of nitrogen-containing heterocycles with aryl halides

In this study, we introduce the ligand complex of copper (II) supported on superparamagnetic Fe3O4@SiO2 nanoparticles as a highly intriguing magnetic catalyst in N-arylation of nitrogen heterocycles with aryl halides. The present methodology offers several advantages such as; low catalyst loading, the use of magnetically recoverable and reusable catalyst, high to excellent yields without using any external ligands or additives, short reaction...
