The formation of C-Se and C-Te bonds is of synthetic and biological importance. Graphene oxide based nano-Fe3O4 (nano-Fe 3O4@GO) is used as a reusable catalyst for the efficient synthesis of diselenides and ditellurides, through cross coupling of Se(0) or Te(0) with aryl iodides. The magnetic heterogeneous catalyst could be easily recovered and reused many times without significant loss of catalytic activity. In addition the superiority of nano-Fe3O4@GO over pristine nano-Fe3O4 is established. Georg Thieme Verlag Stuttgart. New York.

In this study CuO nanoparticles were applied as a catalyst for CSe, CTe, and CS bond formation. The reaction was performed with organoyl iodides and elemental selenium, tellurium or sulfur under microwave irradiation in the presence of a base and solvent at 80 °C. This novel protocol allowed the synthesis of a variety of diselenides, ditellurides and disulfides in good to excellent yields in a very short reaction time.
