Popis:	Silica supported octabromotetraphenylporphyrinatomanganese (III) chloride, Mn(Br 8 TPP)Cl-SiIm, and tetraphenylporphyrinatomangenese (III) chloride, Mn(TPP)Cl-SiIm were used as heterogeneous catalysts for biomimetic oxidation of sulfides with NaIO 4 under agitation with magnetic stirring and sulfoxides and sulfones were obtained as products in high to excellent yields. Ultrasonic irradiation enhanced the catalytic activity of these catalysts in the oxidation of sulfides, reduced the reaction times and increased the product yields. Linear sulfides were completely converted to sulfones while aromatic and cyclic sulfides produced the sulfoxide and sulfone. These new heterogenized catalysts could be reused several times without significant loss of their catalytic activity.
