Manganese(III) Tetraphenylporphyrin Supported on Multi wall Carbon Nanotubes Modified with 2-Aminothiazole As An Efficient Catalyst for Oxidation of Amines with NaIO4

In this work, manganese(III)tetraphenylporphyrin was supported on multi-wall carbon nanotubes modified with 2-aminothiazole. This hetereogeneous catalyst was used as anefficient catalyst for oxidation of amines with sodium periodate under mild conditions. The catalyst was prepared by axial ligation of metal center to preanchored to multi-wall carbon nanotubes, [Mn(TPP)Cl@AT-MWCNT]. The formation of this heterogenized catalyst wasfollowed using elemental analysis, FT-IR spectroscopy, and diffuse reflectance UV-Vis spectrophotometery and scanning electron microscopy. The reactivity of this catalyst in the oxidation of aromatic amines to azo compounds with NaIO4 and also itsr reusability wereinvestigated. The effect of reaction parameters such as solvent and oxidant in the oxidation of aromatic amines were also investigated.
