A novel, versatile and efficient magnetically recoverable palladium nanocatalyst [Fe3O4@SiO2/2-aminopyridine-Pd(II)] was fabricated via the immobilization of palladium(II) complex on the surface of magnetic nanoparticles modified with 2-aminopyridine ligand. The structure of the as-fabricated Fe3O4@SiO2/2-aminopyridine-Pd(II) nanocomposite was characterized by a series of spectroscopic techniques including FT-IR, SEM, TEM, EDX, TGA, XRD, VSM and ICP-OES techniques. The Fe3O4@SiO2/2-aminopyridine-Pd(II) nanocomposite was utilized under mild and eco-friendly conditions in C–S and C–Se coupling reactions to afford a vast variety of diaryl sulfides and diaryl selenides with good to excellent yields. This heterogeneous palladium catalyst can be magnetically separated and reused for at least 7 consecutive trials without any reduction in activity.

A convenient metal-free and solvent-free iodine-catalyzed regioselective greener protocol to access different types of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes through oxidative C-Se/C-S formation via direct C(sp2)-H bond activation was developed. The products were obtained in good to excellent yields using [O or N]-containing arenes, half equiv. of various odorless diorganyl dichalcogenides (S/Se), iodine (20 mol%) as the catalyst and 3 equiv. of DMSO as the oxidant, applying MW irradiation for 10 min.
