Title
Efficient epoxidation of alkenes with sodium periodate catalyzed by reusable manganese(III) salophen supported on multi-wall carbon nanotubes
Abstract

In this paper, efficient epoxidation of alkenes catalyzed by manganese(III) salophen chloride [Mn(salophen)Cl], supported on functionalized multi-wall carbon nanotubes MWCNTs, is reported. The MWCNT was modified with 1,4-diaminobenzene, 4-aminophenol and 4-aminothiophenol and [Mn(salophen)Cl] was attached to the supports via axial ligation. The prepared catalysts were used for efficient epoxidation of alkenes with NaIO4 at room temperature. These new heterogenized catalysts were characterized by elemental analysis, FT-IR spectroscopy, diffuse reflectance UV–vis spectrophotometery and scanning electron microscopy. These heterogeneous catalysts were highly reusable in the oxidation reactions and reused several times without significant loss of their catalytic activity.
