Abstract
Treatment of [CpOs(PPh3)(2)]BF4 in THF with 0.5 equiv of HC=CCH(OH)C=CH fol lowed by Al2O3 gave the C5H-bridged compound [Cp(PPh3)(2)Os=C=C=CHC=COs(PPh 3)(2)Cp]BF4. The analogous iron complex [Cp(dppe)Fe=C=C=CHC=CFe(dppe)Cp]BPh 4 has been prepared similarly. The structure of [Cp(PPh3)(2)Os=C=C=CHC=COs( PPh3)(2)Cp]BF4 has been confirmed by X-ray diffraction. The electrochemical properties of [Cp(dppe)Fe=C=C=CHC=CFe(dppe)Cp]BPh4, [Cp(PPh3)(2)Ru=C=C=CHC =CRu(PPh3)(2)Cp]BF4, and [Cp(PPh3)(2)Os=C= C=CHC=COs(PPh3)(2)Cp]BF4 have be en studied by cyclic voltammetry.
