摘要：

Two novel heterogeneous catalysts have been synthesized by anchoring Cu and Cd Creatinine complexes onto the surface of mesochannels of SBA-15 for highly efficient oxidative coupling of thiols to disulfides using hydrogen peroxide and synthesis of sulfides using S-8 and KOH. The structure of the prepared catalysts was determined using SEM, FT-IR, X-ray diffraction, elemental analysis, N-2 adsorption desorption analysis and TGA. The catalysts significantly enhanced the reaction rate of the oxidative coupling of thiols and C-S bond formations. The catalysts were reused several times without appreciable loss in their activity.
