Selenolatovinylidene complexes: Metal-mediated alkynyl selenoether rearrangements

The reactions of [RuCl2(PPh3)3] and [RuCl-(PPh3)2(η-C5H5)] with PhC≡CSeiPr provide the selenolatovinylidene complexes [RuCl2{=C=C(SeiPr)Ph}(PPhs

Ruthenium(II) diphosphine(phosphine)/imine/amine/CO complexes as efficient catalysts in transfer hydrogenation of ketones

Treatment of [RuCl2(CO)2]n with different phosphine ligands, four Ru(II) complexes of cis-, cis-, trans- RuCl2(CO)2L2 (L = PH(C6H11)2 (1), PPh3 (2), PPh2(C6F5) (3) and PMe3 (4)), in which 1 and 3 are novel complexes, have been generated in methylene chloride and isolated as pure compound in solid. In CH2Cl2 mixed 1:1 molar ratio of RuCl2(PPh3)3 and 1,1′-bis(diphenylphosphine)ferrocene (DPPF), and further reacted with quantitative 2-aminopyridine (ampy), 2-picolylamine (picam) and pyridine ligands, the complexes of RuCl2(DPPF)(ampy) (5), RuCl2(DPPF)(picam) (6) and RuCl2(DPPF)(Py)2 (7) were generated in situ and isolated in solid. All complexes are fully characterized by multinuclear NMR (1H, 13C, 31P and 19F), element analysis and FTIR spectroscopies. Meanwhile, the single crystal structures of 1 and 8 complexes were determined by X-ray crystallography. The observed IR and crystal data of 1 ～ 4 clearly indicate that different phosphine donor ligands occupying trans axis position of Ru(II)Cl2(CO)2 skeleton can affect the coordination carbonyl C-O bond distance (1.143(3) ? (1), 1.135(3) ? (4) and 1.131(5) ? (2)), and this interaction can be quantitatively detected by its FTIR vibration frequencies. The homogeneous hydrogenation transfer catalytic reactivity of so-synthesized complexes has been tested in a basic 2-propanol solution and they indeed perform the catalytic activities in different behavior, e.g. complexes 1 and 6 are the most active catalysts and represent maximum conversion yield (1: 90.4% and 6: 90.0%) and turnover frequency (TOF) (1 18.84 h?1 and 6 37.5 h?1) at our tested experimental condition of these two types of structural complexes, which are discussed in the details.

Reactions of [Ru(CO)2(PPh3)3] with alkynylphosphonium salts: A phosphinoallene complex

[Ru(CO)2(PPh3)3] reacts with either HC=CCH2Br or [HC=CCH2SMe2]Br to provide the σ-allenyl complex [Ru(CH=C=CH2)Br(CO)2(PPh 3)2]; however, with [HC=CCH2PPh3]Br, the salt [Ru(γ2-H2C=C=CHPPh3)(CO) 2(PPh3)2]Br is obtained, which may be described as a complex of a phosphonioallene on the basis of crystallographic data for [Ru(γ2-H2C=C=CHPPh3)(CO) 2(PPh3)2]2Br(PF6) and a comparison of spectroscopic data with those for the simple allene complex [Ru(γ2-H2C=C=CH2)(CO) 2(PPh3)2].

Bis(alkynyl), metallacyclopentadiene, and diphenylbutadiyne complexes of ruthenium

Heating diphenylbutadiyne with [Ru(CO)2(PPh3) 3] or [Ru(CO)3(PPh3)2] in toluene under reflux provides respectively the ruthenacyclopentadiene [Ru{κ2-CR=CPhCPh=CR}(CO)2(PPh3) 2] (R = C≡CPh) or the cyclopentadienone complex [Ru{η4-O=CC4Ph2R2}(CO) 2(PPh3)], the latter via [2 + 2 + 1] alkyne and CO cyclization. The bis(alkynyl) complex cis,cis,trans-[Ru(C≡CPh) 2(CO)2(PPh3)2] is not formed in either of these reactions but is the product of the reaction of [RuCl 2(CO)2(PPh3)2] with LiC≡CPh or of cis,-mer-[Ru(C≡CPh)2(CO)(PPh3)3] with CO. Although the bis(alkynyl) complex does not undergo reductive elimination to provide the diyne complex, thermolysis of cis,cis,trans-[Ru(C≡CPh) (HgC≡CPh)(CO)2-(PPh3)2] (obtained from [Ru(CO)2(PPh3)3] and [Hg(C≡CPh) 2]) provides a noninterconvertible 1:1 mixture of cis,cis,trans-[Ru(C≡CPh)2(CO)2(PPh3) 2] and [Ru(η-PhC≡CC≡CPh)(CO)2(PPh 3)2].

Synthesis, characterization, reactivity and theoretical studies of ruthenium carbonyl complexes containing ortho-substituted triphenyl phosphanes

A series of ruthenium o-phosphane complexes was synthesized and characterized. The reactivity of the prepared complexes was studied by using them as catalysts for the hydroformylation of 1-hexene. The activities depended on the binding mode of the phosphane and on the strength of the ruthenium-phosphane interaction. Strongly coordinated chelating [2-(dimethylamino)phenyl]-(diphenyl) phosphane and [2-(methylthio)phenyl]- (diphenyl) phosphane showed poor activity, while weakly chelated [2-(methoxy)phenyl]-(diphenyl) phosphane and non-chelating phosphanes such as [2-(methyl)phenyl]-(diphenyl) phosphane or [2-(ethyl)phenyl]-(diphenyl) phosphane led to higher activities.

Binuclear ruthenium macrocycles formed via the weak-link approach

The weak-link approach for the synthesis of metallomacrocycles has been used to synthesize a series of novel Ru(II) macrocycles in high yield. RuCl2(PPh3)3 has been reacted with two different phosphino-alkyl-ether hemilabile ligands, 1,4-(PPh2(CH 2)2O)2C6H4 and 1,4-(PPh2(CH2)2OCH2) 2C6H4. The hemilabile bidentate ligand coordinates to Ru(II) centers through both the P and O atoms to form bimetallic condensed intermediates . The weak Ru-O bonds have been selectively cleaved with CO, 1,2-diaminopropane, and pyridine to yield large open macrocycles. This is the first example of the weak-link approach employed to synthesize macrocycles with Ru, and metal centers in general that have more than four coordination sites.

A facile route to carbonylhalogenometal complexes (M = Rh, Ir, Ru, Pt) by dimethylformamide decarbonylation

Dimethyl formamide (DMF) can be a convenient source of the carbonyl ligand in the coordination chemistry of rhodium, ruthenium, iridium, and platinum. We have undertaken a thorough study concerning the course of this reaction. In a first step, DMF-containing complexes are produced, which is usually accompanied by chloride redistribution. Then, upon refluxing, carbonyl species in the same oxidation state are obtained, presumably as a result of HCl-mediated DMF decomposition. Provided that water levels are kept low, reduction can occur to provide the complexes [NH2(CH3)2][RhCl2(CO) 2], [NH2(CH3)2][RuCl3(CO) 2(DMF)], [RuCl2(CO)2(DMF)2], and [NH2(CH3)2][IrCl2(CO) 2]. In the case of platinum, reduction is not effective and [NH2(CH3)2][PtCl3(CO)] is obtained. No carbonylpalladium species can be synthesized in this way, the reaction producing copious amounts of colloidal metal. Adding phosphanes to these chlorocarbonyl-containing solutions allows easy, one-step syntheses of a variety of complexes.

Synthesis and molecular structure of [RuCl{C(=CHPh)OC(=O)CH2CH3}(CO)(PPh3) 2]: A real intermediate in ruthenium complex-catalyzed selective synthesis of a (Z)-enol ester

Reaction of [RuCl(η2-O2CCH2CH3)(CO)(PPh 3)2] (1) and phenylacetylene gives [RuCl{C(=CHPh)OC(=O)CH2CH3}(CO)(PPh3) 2] (2a). The X-ray structure analysis of 2a reveals that it includes a (Z)-enol ester-like 1-propanoyloxy-2-phenylethenyl-C1,O ligand. In the catalytic addition of propanoic acid to phenylacetylene, the complex 2a acts as a real intermediate that gives (Z)-2-phenylethenyl propanoate, selectively. The presence of the free PPh3 in the reaction mixture depresses formation of some dicarbonylruthenium species that catalytically produce (E)- and Markovnikov-type enol esters.

Tetravalent tellurium ligands

Oxidative addition of TeCl4 to Vaska's complex gave the trichlorotelluronium complex [IrCl2-(TeCl3)(CO)(PPh3)2] (structure depicted), which contains a rare example of a structurally characterized tetravalent tellurium ligand. The coordination at the Te(IV) center is - in full agreement with the VSEPR model - distorted trigonal bipyramidal.
