Biomimetic epoxidation of alkenes with sodium periodate catalyzed by Nano-Silica Supported Manganese Salophen

In this work, efficeint epoxidation of alkenes catalyzed by manganese(III) salophen chloride,[Mn(salophen)Cl], supported on nano-silica is reported. In this manner, the Mn(Salophen)Cl wasattached to nano silica via axial ligation. The catalyst, [Mn(salophen)Cl@NH2-Nano-SiO2], was usedas an efficient and hetereogeneous catalyst for rapid epoxidation of alkenes with sodium periodate under mild conditions and the corresponding carbonyl compounds were produced in high to excellent yield. These heterogenized catalysts were used as efficient and reusable catalysts for epoxidation of a variety of cyclic and linear alkenes with sodium periodate under mild conditions.
