Manganese(III) Tetraphenylporphyrin Supported on Magnetic Nanoparticles: An Efficient Catalyst for Biomimetic Oxidation of Sulfides with NaIO4

A green, efficient and highly selective method for oxidation of sulfides to their corresponding sulfoxides and sulfones with sodium periodate using manganese(III)tetraphenylporphyrin supported on multiwall carbon-nanotubes was developed under mild conditions. The oxidation procedure is very simple and the products are easily isolated in excellent yields (90-99%).
