Metal-free C-Se cross-couplingsviathe formation of electron-donor-acceptor (EDA) complexes have been developed. The visible-light induced reactions can be applied for the synthesis of a series of unsymmetrical diaryl selenides employing aryl bromides, aryl iodides as well as aryl chlorides under mild reaction conditions. The scale-up was readily achieved. UV-Vis spectroscopy measurements provide insight into the reaction mechanism.

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.

This report describes a method for Ni-catalyzed intramolecular decarbonylative coupling, which enables the conversion of areneselenol esters to diaryl selenides. The inexpensive and readily available catalyst can be employed under mild reaction conditions for the construction of structurally diverse diaryl selenides, including heterocyclic and natural product derivatives.
