چکیده مقاله :
Boehmite is easily available and also it has a variety of applications. Therefore in this work, boehmite nanoparticles (AlOOH-NPs) were prepared and its surface was modified with (3-aminopropyl)triethoxysilane (APTES). Then, di(pyridin-2-yl)methanone (di(PM)) was immobilized on the surface of modified AlOOH-NPs. In the final step, a palladium complex was stabilized on its surface (Pd-di(PM)@AlOOH-NPs). This nanocatalyst was characterized by TGA, FT-IR, SEM, EDS, WDX, and ICP techniques. Then, Pd-di(PM)@AlOOH was used as a highly practical, stable, retrievable, and hybrid of organic-inorganic catalyst in the C-C coupling of Suzuki reaction. This nanocatalyst was reused for several runs without palladium leaching or any re-activation. (Scheme).
