Abstract	In the present study, preparation, characterization, and catalytic activity of Ru(salophen)Cl supported on chitosan were investigated. The prepared heterogeneous catalyst was characterized by diffuse reflectance UV–vis and FT-IR spectroscopic techniques, scanning electron microscopy, and neutron activation analysis. In this catalytic system, the effects of different solvents were studied in the epoxidation of cis-cyclooctene and CH$_{3}$CN/H$_{2}$O was found to be a better solvent. Also, the effects of oxygen donors such as NaIO$_{4}$, H$_{2}$O$_{2}$, H$_{2}$O$_{2}$/urea(UHP), tert-BuOOH, NaClO, and Bu$_{4}$NIO$_{4}$ were studied in the epoxidation of cis-cyclooctene and NaIO$_{4}$ was selected as an oxidant. The catalytic activity of this new heterogeneous catalyst in the epoxidation of cyclic and linear alkenes using NaIO$_{4}$ as an oxidant in CH$_{3}$CN/H$_{2}$O at room temperature was studied. The obtained results led us to conclude that [Ru(salophen)Cl@ chitosan] is an efficient catalyst for the epoxidation of alkenes with NaIO$_{4}$. The catalyst can be readily recovered simply by filtration and reused several times without any significant loss in its catalytic activity.
