Abstract

AbstractAn iron (II) complex with oxazoline and pyrrole functional groups was prepared and used to catalyze the epoxidation of alkenes by m‐chloroperoxybenzoic acid. The iron (II) complex exhibited good catalytic activity for the epoxidation of aromatic terminal alkenes and cyclic alkene in acetonitrile. The 99.7 % conversion of styrene with 91.2 % selectivity of styrene oxide was achieved after reaction 30 minutes at 25 °C. The auxiliary ligands, solvents and oxidants are sensitive to the epoxidation reaction. A possible catalytic mechanism for epoxidation of alkene was proposed.
