✦ Synopsis
An inorganic polymer-platinum complex, magnesiasupported polytitanzane-platinum complex (MgO-Ti-N-Pt), was prepared and used to catalyze the oxygenation of benzyl alcohol. It was found that this kind of catalyst has great activity and stability in the reaction. The objective product (benzaldehyde) was obtained in 100% yield in 6 hr under a moderate reaction temperature and atmospheric oxygen pressure. This inorganic polymer complex was also very stable during the reaction.
