A series of aryl iodides, with a range of substituents, has been successfully coupled using 10 mol percent Pd catalyst with samarium thiolates, derived from the corresponding aryl thiocyanates upon reductive cleavage with SmI2. Reactions proceed in THF at 65°C in yields ranging from good to excellent and are compatible with both electron-donating and electron-withdrawing substituents, except NO2. The reactions may also be conducted with aryl bromides although with somewhat lower yields.

This work describes an electrochemical enabled nickel-catalyzed chemoselective C?S bond coupling protocol for the production of aryl sulfides and sulfones. By simply switching the nickel catalysts and electrodes, this electrochemical C?S bond coupling has demonstrated excellent redox activity, scalability and sustainability. Furthermore, the mechanism for this electrochemical cross-coupling reaction has been investigated.

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.
