Mn(II) salen complex immobilized on nano silicagel as a recyclable heterogeneous catalyst for oxidation of alcohols to their corresponding carbonyl compounds
Journal Title: Iranian Chemical Communication - Year 2016, Vol 4, Issue 3
Abstract
Mn(II) salen complex immobilized on nano silicagel was prepared by incorporating Mn(II) salen complex into a nanosilica matrix and characterized by TGA, XRD, atomic absorption spectroscopy and was successfully applied as catalyst for the oxidation of alcohols. Oxidation of a series of alcohols in acetonitrile over immobilized Mn(II) salen complex using tetrabutylammonium peroxymonosulfate (TBAO) as oxidant were resulted to the corresponding carbonyl compounds selectively in moderate to high yields. It is noteworthy that the aldehydes do not undergo further oxdation to carboxylic acids. The yields of aromatic alcohols are higher than those of alcohols with aliphatic groups. The catalyst has been reused several times, without observable loss of its activity and selectivity.
