Abstract: A tetradentate ligand together with its manganese complex has been synthesized and characterized. The complex was screened for the catalytic epoxidation of a broad range of olefins using AcO₂H as the oxidant. The efficient epoxidation of a family of olefins has been accomplished by the manganese catalyst that exhibits an uncommon chemoselectivity with low catalyst loading (0.5 mol%), fast conversion (5 min) and high yields (85%-99%).

Key words: epoxidation; manganese complex; peracetic Acid; alkene, chemoselectivity
