Abstract
A nitrogen ligand, i.e. 1,3-di-(o-aminophenoxy)-2-propyl propargyl ether (DPPE), has been synthesized and characterized. Magnetic mesoporous silica composite (MNP@SiO.sub.2-SBA) was obtained via embedding magnetite nano-particles (MNPs) between SBA-15 channels. DPPE palladium dichloride (MNP@SiO.sub.2-SBA-DPPE-Pd(II)) was then prepared via click chemistry and fully characterized. The Hiyama reaction conditions including solvent, amount of catalyst, base and temperature were optimized for the prepared catalyst. The activity and recyclability of supported magnetic Pd(II) catalyst were evaluated under the optimal reaction conditions. The catalyst was easily separated magnetically, reused in five runs sequentially, and no significant loss of activity was observed. Graphical Abstract
