Supported Mn(salen)Cl was prepared by immobilization of a homogeneous Mn(salen)Cl complex onto
cellulose and characterized by FT-IR, TGA and atomic absorption spectroscopy. This heterogeneous
catalyst is able to effectively catalyze the oxidation of aromatic sulfides in good yield under mild
conditions. The catalytic activity of Mn(salen)Cl and [Mn(salen)Cl–cellulose] in this reaction was
investigated. The heterogeneous catalyst showed higher catalytic activity with respect to the neat
Mn(salen)Cl complex. The key advantages of this process are cost effectiveness of the catalyst,
reusability of the catalyst and easy work-up.
