Treatment of [CpOs(PPh3)2]BF4in THF with 0.5 equiv of HC≡CCH(OH)C≡CH followed by Al2O3gave the C5H-bridged compound [Cp(PPh3)2Os=C=C=CHC≡COs(PPh3)2Cp]BF4. The analogous iron complex [Cp(dppe)Fe=C=C=CHC≡CFe(dppe)Cp]BPh4has been prepared similarly. The structure of [Cp(PPh3)2Os=C=C=CHC≡COs(PPh3)2Cp]BF4has been confirmed by X-ray diffraction. The electrochemical properties of [Cp(dppe)Fe=C=C=CHC≡ CFe(dppe)Cp]BPh4, [Cp(PPh3)2Ru=C=C=CHC≡CRu(PPh3)2Cp]BF4, and [Cp(PPh3)2Os=C= C=CHC≡COs(PPh3)2Cp]BF4have been studied by cyclic voltammetry.
