Abstract: Manganese(III)tetraphenylporphyrin supported on multi-wall carbon nanotubes (MWCNTs) were developed as efficient catalysts for epoxidation of alkenes with sodium periodate under mild conditions. The catalysts were prepared by axial ligation of manganese to 2-aminobenzimidazole and 2-aminothiazole preanchored to MWCNTs. The formation of these heterogenized catalysts was followed using elemental analysis, FT-IR spectroscopy, diffuse reflectance UV-Vis spectrophotometry, and scanning electron microscopy. The reactivity of these catalysts under both magnetic stirring and ultrasonic irradiation and also their reusability were investigated.
