Аннотация: The interaction between Cp(CO)2ReCCHPh (1) and CuCl results in the new heterometallic μ-vinylidene complex [Cp(CO)2ReCu(μ2-CCHPh)(μ2-Cl)]2 (2) characterized earlier by IR and 1H, 13C NMR spectra. The molecular structure of compound 2 has been determined by X-ray diffraction analysis, revealing a dimer structure with two binuclear fragments linked to each other by asymmetric chloride bridges. The electrochemical behavior of 2 in acetonitrile was studied by cyclic voltammetry at a Pt-electrode.

Аннотация: The reaction of [Cp(CO)2ReCCHPh] (1) with [Pd(PPh3)4] followed by the treatment of resulting [Cp(CO)2RePd(μ-CCHPh)(PPh3)2] (2) with diphosphines (dppe, dppp) gave new complexes [Cp(CO)2RePd(μ-CCHPh)(dppe)] (3) and [Cp(CO)2RePd(μ-CCHPh)(dppp)] (4). Treatment of the synthesized complexes with [Fe2(CO)9] led to mixtures of [Cp(CO)2ReFe(μ-CCHPh)(CO)4] (5), [(dppe)PdFe2(CO)8] (6), [CpReFe2(μ3-CCHPh)(CO)8] (7), [CpReFePd(μ3-CCHPh)(CO)5(dppe)] (8) and of 5, [(dppp)PdFe2(CO)8] (9), [CpReFePd(μ3-CCHPh)(CO)5(dppp)] (10), respectively. The main products of both reactions were trinuclear μ3-vinylidene clusters 8 and 10. Reactions of the trinuclear μ3-vinylidene ReFePd clusters 8 and 10 with Fe2(CO)9 were also studied. New complexes were characterized by IR, 1H, 13C, 31P NMR spectroscopy and cyclic voltammetry. The structure of [CpReFe2(μ3-CCHPh)(CO)8] was determined by single-crystal X-ray diffraction.

Аннотация: The novel tetranuclear di-vinylidene complex Cp2(CO)4RePd(μ2-CCHPh)RePd(μ3-CCHPh)(dppe) was isolated and characterized by X-ray diffraction. This cluster consists of two RePd fragments linked to each other through the bonding of the palladium atom in the [Cp(CO)2RePd(μ-CCHPh)] fragment to the carbonyl and vinylidene ligands in the Cp(CO)2RePd(μ-CCHPh)(dppe) fragment.

Аннотация: The novel heterobinuclear μ-vinylidene complex [Cp(CO)2Re(μ-C=CHPh)Pt(PPh3)(CO)] (1) was isolated from the reaction mixture of [Cp(CO)2Re(μ-C=CHPh)Fe(CO)4] and Pt(PPh3)4 for the first time. Alternative high-yield synthetic approaches to 1 were developed including the reactions of [Cp(CO)2Re(μ-C=CHPh)Pt(PPh3)2] (2) with Co2(CO)8 and Rh(acac)(CO)2. The complex was characterized by IR and ¹H, ¹³C and ³¹P NMR spectroscopy, a molecular structure of 1 was determined by X-ray diffraction analysis. The electrochemical behavior of the new complex was studied by cyclic voltammetry at platinum or glassed carbon electrodes and by dc polarography at a dropping mercury electrode.

Аннотация: Reactions of Cp(CO)2ReCCHPh with Pt[P(OR)3]4 (R = Pri, Et, Ph) gave binuclear μ-vinylidene complexes Cp(CO)2RePt(μ-CCHPh)[P(OR)3]2. Treatment of the previously synthesized Cp(CO)2Re(μ-CCHPh)Pt(PPh3)2 with triisopropylphosphite or triethylphosphite resulted in a stepwise substitution of PPh3 ligands, leading to the disubstituted Cp(CO)2RePt(μ-CCHPh)[P(OR)3]2 and monosubstituted Cp(CO)2RePt(μ-CCHPh)[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-CCHPh)[P(OR)3](PPh3) (R = Pri, Et, Ph) species were also obtained by reacting Cp(CO)2ReCCHPh with mixed-ligand complexes Pt(PPh3)3L (L = P(OPri)3, P(OEt)3, P(OPh)3). Reactions of Cp(CO)2RePt(μ-CCHPh)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-CCHPh)[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-CCHPh)[P(OPri)3]2, Cp(CO)2RePt(μ-CCHPh)[P(OPri)3](PPh3) and Cp(CO)2RePt(μ-CCHPh)[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.

Аннотация: The interaction between Cp(CO)(2)RePt(mu-C=CHPh)(PPh(3))(2) (1) and Fe(2)(CO)(9) afforded the new heterometallic mu(3)-vinylidene cluster CpReFePt(mu(3)-C=CHPh)(CO)(6)(PPh(3)) (2). An X-ray diffraction study shows the complex 2 possesses a trimetallic Re-Fe-Pt chain core. The bond lengths are Re-Fe 2.8221(8), Fe-Pt 2.5813(8) angstrom; the Re center dot center dot center dot Pt distance is 3.3523(7) angstrom; the bond angle Re-Fe-Pt is 76.55(3)degrees. The mu(3)-C=CHPh ligand is eta(1)-bound to the Re and Pt atoms and eta(2)-coordinated to the Fe atom. The C=C bond length is 1.412(4) angstrom. The Pt atom is coordinated by the PPh(3) and CO groups. Complex 2 is characterized by the IR and (1)H, (13)C and (31)P NMR spectra. (C) 2008 Elsevier B.V. All rights reserved.

Аннотация: The reactions of Cp(CO)(2)Re=C=CHPh (2) with M(PPh(3))(4) (M = Pd, Pt) gave the mu-vinylidene complexes Cp(CO)(2)RePd(mu-C=CHPh)(PPh(3))(2) (3) and Cp(CO)(2)RePt(mu-C=CHPh)(PPh(3))(2) (1), respectively. The substitution of Ph(2)PCH(2)PPh(2) (dppm) for the PPh(3) ligands in 1 resulted in the formation of Cp(CO)RePt(mu-C(1)=C(2)HPh)(mu-CO)(dppm) (4). The structure of complex 4 has been determined by single-crystal X-ray diffraction analysis. The structural and spectroscopic characteristics of complexes 1, 3, and 4 were compared with the corresponding parameters of the manganese-containing analogs Cp(CO)(2)MnPd(mu-C=CHPh)(PPh(3))(2) (5), Cp(CO)(2)MnPt(mu-C=CHPh)(PPh(3))(2) (6) and Cp(CO)(2)MnPt(mu-C=CHPh)(dppm) (7).
