Biomimetic Oxidation of Sulfides with Sodium Periodate Catalyzed by Manganese(III) Tetraphenylporphyrin Supported on Multi wall Carbon Nanotubes Modified with 2-Aminobenzimidazole

In this work, first, multi-wall carbon nanotubes were modified with 2-aminbenzimidazole and then manganese(III)tetraphenylporphyrin was suppoertd on the modified carbon nanotubes via axial ligation. The catalyst, [Mn(TPP)Cl@ABI-MWCNT], was used as an efficient catalyst for oxidation of sulfides to sulfoxides and sulones with sodium periodate. The prepared heterogenized catalyst was characterized by elemental analysis, FT-IR spectroscopy, and diffuse reflectance UV-Vis spectrophotometery and scanning electron microscopy. The effect of reaction parameters such as solvent and oxidant in the oxidation of sulfides and also the catalyst reusability were also investigated
