摘要：

A new iron(II) complex bearing an N3S2 thioether ligand was synthesized and characterized with various spectroscopic techniques and X-ray crystallography. A mononuclear nonheme iron(IV)-oxo intermediate was generated in the reaction of the iron(II) complex with various terminal oxidants. Theiron (IV)-oxo species show a capability of epoxidizing olefins, and the olefin epoxidation occurs via an electrophilic oxidation mechanism. (C) 2008 Elsevier B.V. All rights reserved.
