The reactivity of the benzenedithiolate (bdt)-bridged complex [Fe2(CO)6(µ-bdt)] with arsine, stibine and phosphine ligands has been studied. new mono- disubstituted complexes [Fe2(CO)5(EPh3)(µ-bdt)] (E = As, 1; E Sb 3) [Fe2(CO)4(EPh3)2(µ-bdt)] 2; Sb, 4) previously reported [Fe2(CO)4(PPh2H)2(µ-bdt)] (5) have prepared by Me3NO-initiated carbonyl substitution reactions appropriate at 80 °C. Spectroscopic single-crystal X-ray diffraction studies reveal that in all cases introduced occupy apical coordination site(s) lying trans to iron–iron bond. Their electrochemistry probed cyclic voltammetry selected tested as proton reduction catalysts. Monosubstituted 1 3 show two irreversible reductions ca. −1.7 V −2.0 V, respectively, relative Fc+/Fc, while 2 5 a single −2.2 −1.84 respectively. Complexes 1, can catalyse electrocatalytic presence either p-toluene sulfonic acid (TsOH) or trifluoroacetic (CF3CO2H).
