Abstract
|
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
