Reactions of Cp(CO)2Re[dbnd]C[dbnd]CHPh with Pt[P(OR)3]4 (R = Pri, Et, Ph) gave binuclear μ-vinylidene complexes Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OR)3]2. Treatment of the previously synthesized Cp(CO)2Re(μ-C[dbnd]CHPh)Pt(PPh3)2 with triisopropylphosphite or triethylphosphite resulted in a stepwise substitution of PPh3 ligands, leading to the disubstituted Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OR)3]2 and monosubstituted Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OR)3](PPh3) (R = Pri or Et) species, while no triphenylphosphine ligand substitution in the reaction with P(OPh)3 occurs at all. The monosubstituted Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OR)3](PPh3) (R = Pri, Et, Ph) species were also obtained by reacting Cp(CO)2Re[dbnd]C[dbnd]CHPh with mixed-ligand complexes Pt(PPh3)3L (L = P(OPri)3, P(OEt)3, P(OPh)3). Reactions of Cp(CO)2RePt(μ-C[dbnd]CHPh)LL′ (L = L′ = P(OPri)3, P(OEt)3, P(OPh)3; L = P(OPri)3, P(OEt)3, P(OPh)3, L′ = PPh3) with Co2(CO)9 yield tricarbonyl vinylidene species Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OR)3](CO) (R = Pri, Et, Ph). The obtained compounds were characterized by IR and 1H, 13C, 31P NMR spectroscopy. The molecular structures of Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OPri)3]2, Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OPri)3](PPh3) and Cp(CO)2RePt(μ-C[dbnd]CHPh)[P(OPri)3](CO) were determined by X-ray diffraction study. The redox properties of the new complexes and their reactions of chemical oxidation were studied.
