The catalytic activity of Mn(salen)Cl containing tert-pentyl groups at the 3,5-positions of the salen ligand in the epoxidation of
alkenes and hydroxylation of alkanes was studied at room temperature, using sodium periodate as an oxygen source. The effects
of various axial ligands were investigated in the epoxidation of cyclooctene. Imidazole, as a strong ً-donor ligand, was the best
axial ligand. The effect of different solvents was studied in the epoxidation of cyclooctene in CH3CN/H2O solvent mixture. The
epoxidation reactions of cyclooctene by different oxygen donors including NaIO4, Bu4NIO4, KHSO5, H2O2, H2O2/urea, NaOCl
and tert-BuOOH were also studied and NaIO4 was selected as oxygen source. The presence of bulky substituents in the 3,5-
positions of the salen ligand was found to increase the catalytic activity of this complex.
