Summary: | A green, new, and efficient catalyst was successfully synthesized by the immobilization of Co as a transition metal on SBA-15 Then, this mesostructured material was characterized by TGA, SEM, FT‐IR, ICP, BET and X-ray mapping analytical. The prepared catalyst was used for the oxidation of sulfides the synthesis of polyhydroquinoline derivatives. The use of non-toxic materials, easy separation, easy operation, high yields of the products are the most important advantages of this method.

In this work, a green and novel catalyst was prepared through immobilization of cobalt complex on the surface of mesostructured SBA-15 and characterized by TGA, SEM, FT‐IR, EDX, ICP, BET and X-ray mapping analytical methods. This mesostructural material was used as an efficient and green interphase catalyst for the oxidation reactions and synthesis of polyhydroquinoline derivatives. All reactions were performed in short times and good yields. Moreover, the prepared catalyst could be used up to six runs without significant degradation in its catalytic activity or cobalt leaching. |
