Manganese(iii)salophen supported on a silica containing triazine dendrimer: an efficient catalyst for epoxidation of alkenes with sodium periodate

摘要

In this paper, Mn( III ) salophen supported on a nanosilica triazine dendrimer was synthesized and characterized by FT-IR, UV-vis spectroscopic methods, SEM, TEM, TGA and ICP analyses. This catalyst was used in the epoxidation of different cyclic and linear alkenes with sodium periodate under agitation with magnetic stirring. Furthermore, the influence of vital reaction parameters such as solvent, oxidant and amount of catalyst on the epoxidation of alkenes was investigated. This heterogeneous catalyst shows high stability and reusability in the epoxidation of alkenes.
