Abstract
|
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 S8 and KOH. The structure of the prepared catalysts was determined using SEM, FT-IR, X-ray diffraction, elemental analysis, N2 adsorption– desorption analysis and TGA. The catalysts significantly enhanced the reaction rate of the oxidative coupling of thiols and CAS bond formations. The catalysts were reused several times without appreciable loss in their activity.
