An unprecedented transfer of selenium ion from potassium selenocyanate was observed in C-Se cross-coupling reaction catalyzed by copper oxide nanoparticles under ligand-free conditions. Utilizing this protocol wide range of symmetrical diaryl selenides were obtained in excellent yields. Nano-CuO is recyclable up to four cycles without loss of catalytic activity.

In the present work, microporous nitrogen containing covalent triazine polymers (CTPs) TATAM was synthesized from condensation of 4,4′4′′-(1,3,5-triazine-2,4,6-triyl) tribenzaldehyde (TATA) and melamine under solvothermal conditions to obtain nitrogen- rich triazine containing polymeric supported materials (TATAM). Further, palladium nanoparticles (Pd NPs) were supported on TATAM polymeric networks (Pd@TATAM). The synthesized Pd@TATAM CTPs material was thoroughly characterized by FT-IR, UV-DRS, solid state 13C-CPMAS, XPS, powder X-ray diffraction, TGA, SEM, TEM. In addition, the characterized Pd@TATAM CTPs were applied to check the catalytic application. The Pd@TATAM was shown to be an efficient and reusable heterogeneous solid catalyst for the formation of C?Se bond through coupling of aryl halide and elemental selenium, dimethyl sulfoxide as a solvent at 100 °C for about 6 h. Besides the absence of metal leaching for catalytic system, it is also observed that the catalyst can be reused for three consecutive cycles with a minimal decrease in its activity.
