“…As an extension of our study on synthesis and reactivity of heterometallic vinylidene complexes and clusters, we examined the possibility of synthesizing the known trinuclear cluster CpReFePt(µ 3 -C=CHPh)(CO) 6 (PPh 3 ) [27] [23]. Following these strategy, we attempted to prepare complex 1.…”

“…The second yellow band after evaporation of solvent and crystallization of a crude product from benzene-hexane mixture ( The third green-brown fraction after removal of solvent gave 32 mg (43%) of cluster [CpReFePt(μ 3 -C=CHPh)(CO) 6 PPh 3 ] that identified by IR spectra [27].

“…It should be noted that the carbon monoxide can initiate a cleavage of metal-metal bond and lead to decomposition of starting compound, for example, reactions of µ-carbene complexes with CO lead to formation of triangular clusters containing Pt 3 cores [24][25][26]. Reactions with metal carbonyl complexes can be accompanied by formation of trinuclear clusters [22,27,28]. However, in the case of reactions of the binuclear vinylidene complexes [Cp(CO) 2 Mn(μ-C=CHPh)Pt(L) 2 ] (L = PPh 3 , P(OPr i 3 )) with Co 2 (CO) 8 , the substitution of L by CO occured without decomposition to give tricarbonyl vinylidene species [Cp(CO) 2 Mn(μ-C=CHPh)Pt(L)(CO)] in high yields [23].…”

The novel heterobinuclear μ-vinylidene complex [Cp(CO) 2 Re(μ-C=CHPh)Pt(PPh 3)(CO)] (1) was isolated from the reaction mixture of [Cp(CO) 2 Re(μ-C=CHPh)Fe(CO) 4 ] and Pt(PPh 3) 4 for the first time. Alternative high-yield synthetic approaches to 1 were developed including the reactions of [Cp(CO) 2 Re(μ-C=CHPh)Pt(PPh 3) 2 ] (2) with Co 2 (CO) 8 and Rh(acac)(CO) 2. The complex was characterized by IR and 1 H, 13 C and 31 P 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.

Комплексы Cp(CO) 2 Re(μ-C=CHPh)Pt(P-P) (P-P = dppe (7); dppp (8)) и CpReFePt(µ 3 -C=CHPh)(CO) 6 (PPh 3 ) (3) синтезированы по методикам [20,23].

“…Первый μ 3 -винилиденовый кластер, содержащий атом рения CpReFePt(µ 3 -C=CHPh)(CO) 6 (PPh 3 ) (3), был получен относительно недавно, в 2009 г. [20], позже синтезированы и охарактеризованы кластер CpReFePt(µ 3 -C=CHPh)(CO) 5 [P(OPr i ) 3 ] 2 (4) и кластеры, содержащие металлический остов ReFePd и хелатные дифосфиновые лиганды при атоме палладия, CpReFePd(µ 3 -C=CHPh)(CO) 5 (P-P) (P-P = dppe (5), dppp (6)) [21,22]. Поэтому поиск новых путей синтеза, изучение закономерно-стей образования и свойств гетерометаллических винилиденовых комплексов рения является актуальным.…”
