Abstract

Abstract: Herein, we report the preparation and characterization of two diiron carbonyl complexes with ethyldiphenylphosphine or dicyclohexylphenylphosphine. Me3 NO-driven decarbonylation of complex [Fe2 (CO)6 ( µ -SCH2 CH2 CH2 S)] (1 ) with the corresponding phosphine ligands afforded the products [Fe2 (CO)5 (Ph2 PCH2 CH3 )( µ -SCH2 CH2 CH2 S)] (2 ) and [Fe2 (CO)5 PhP(C6 H11 )2 ( µ -SCH2 CH2 CH2 S)] (3 ) in 91% and 84% yields, respectively. The structures of complexes 2 and 3 have been identified by spectroscopy, elemental analysis, and X-ray diffraction analysis. Moreover, the electrochemistry was investigated by cyclic voltammetry.
