Abstract

We have prepared three diiron ethane-1,2-dithiolate complexes [Fe2(CO)5L(µ-SCH2CH2S)] [L = P(C6H11)3, 2; Ph2POCH3, 3; P(2-C4H3S)3, 4] by CO exchange of the starting complex [Fe2(CO)6(µ-SCH2CH2S)] (1) with the corresponding phosphine ligands tricyclohexylphosphine, methyl diphenylphosphinite, or tris(2-thienyl)phosphine in the presence of Me3NO as an oxidant for CO. The complexes have been characterized by elemental analysis, spectroscopy, and single-crystal X-ray diffraction analysis.
