Abstract Treatment of the starting complex [Fe2(CO)6{μ-SCH2CH(CH2OH)S}] (1) with 2-(diphenylphosphino)benzoic acid in the presence of N,N’-dicyclohexylcarbodiimide and 4-dimethylaminopyridine gave the corresponding ester derivative [Fe2(CO)6{μ-SCH2CH(CH2O2CC6H4PPh2-2)S}] (2) in 92% yield. Further treatment of complex 2 with one equivalent of Me3NO · 2 H2O as the decarbonylating agent yielded diphenylphosphino-substituted complex [Fe2(CO)5{μ-SCH2CH(CH2O2CC6H4PPh2-2)S}] (3) in 79% yield. Both complexes were characterized by elemental analysis, spectroscopy, as well as by X-ray crystallography. Additionally, the electrochemical properties of these complexes were studied by cyclic voltammetry. Graphical Abstract
