In Situ FTIR and NMR Spectroscopic Investigations on Ruthenium-Based Catalysts for Alkene Hydroformylation

Homogeneous ruthenium complexes modified by imidazole-substituted monophosphines as catalysts for various highly efficient hydroformylation reactions were characterized by in situ IR spectroscopy under reaction conditions and NMR spectroscopy. A proper protocol for the preformation reaction from [Ru3(CO)12] is decisive to prevent the formation of inactive ligand-modified polynuclear complexes. During catalysis, ligand-modified mononuclear ruthenium(0) carbonyls were detected as resting states. Changes in the ligand structure have a crucial impact on the coordination behavior of the ligand and consequently on the catalytic performance. The substitution of CO by a nitrogen atom of the imidazolyl moiety in the ligand is not a general feature, but it takes place when structural prerequisites of the ligand are fulfilled.

Formic acid as a hydrogen storage medium: Ruthenium-catalyzed generation of hydrogen from formic acid in emulsions

Formic acid is decomposed to H2 and CO2 in the presence of RuCl3 and triphenylphosphines in an emulsion. In situ formed ruthenium carbonyls, such as [Ru(HCO2)2(CO) 2(PPh3)2] (1), [Ru(CO)3(PPh 3)2] (2), and [Ru2(HCO2) 2(CO)4(PPh3)2] (3), and a large cluster, involving a Ru12 core, were identified and structurally characterized from the reaction mixtures. The catalytic activity of the mono and binuclear complexes was also investigated and it was found that [Ru 2(HCO2)2(CO)4(PPh3) 2] (3) shows high stability even at elevated temperatures and pressures and its activity is 1 order of magnitude lower than those measured for the mononuclear complexes. It was also attempted to use [Ru(HCO 2)2(CO)2(PPh3)2] (1) as a catalyst for the hydrogenation of CO2 to formic acid under neutral conditions. Although the reduction of CO2 did not take place, the conversion of [Ru(HCO2)2(CO)2(PPh 3)2] (1) to an unexpected carbonate, [Ru(CO 3)(CO)2(PPh3)2]·H 2O was observed.

Acrylic acid derivatives of group 8 metal carbonyls: A structural and kinetic study

The synthesis, spectroscopic, and X-ray structural studies of acrylic acid complexes of iron and ruthenium tetracarbonyls are reported. In addition, the deprotonated η2-olefin bound acrylic acid derivative of iron as well as its alkylated species were fully characterized by X-ray crystallography. Kinetic data were determined for the replacement of acrylic acid, acrylate, and methylacrylate for the group 8 metal carbonyls by triphenylphosphine. These processes were found to be first-order in the concentration of metal complex with the rates for dissociative loss of the olefinic ligands from ruthenium being much faster than their iron analogues. However, the ruthenium derivatives afforded formation of primarily mono-phosphine metal tetracarbonyls, whereas the iron complexes led largely to trans-di-phosphine tricarbonyls. This difference in behavior was ascribed to a more stable spin crossover species 3Fe(CO)4 which undergoes rapid CO loss to afford the bis phosphine derivative. The activation enthalpies for dissociative loss of the deprotonated η2-bound acrylic acid ligand were found to be larger than their corresponding values in the protonated derivatives. For example, for dissociative loss of the protonated and deprotonated acrylic acid derivatives of iron(0) the ΔH? values determined were 28.0 ± 1.2 and 34.1 ± 1.5 kcal·mol-1, respectively. Density functional theory (DFT) computations of the bond dissociation energies (BDEs) in these acrylic acids and closely related complexes were in good agreement with enthalpies of activation for these ligand substitution reactions, supportive of a dissociative mechanism for olefin displacement. Processes related to catalytic production of acrylic acid from CO2 and ethylene are considered.

Photochemical synthesis of ruthenium-carbonyl compounds with thioether ligands and subsequent oxidative cleavage of trinuclear complexes by chlorinated solvents

The photochemical reaction of [Ru3(CO)12] with thioether ligands in THF leads to the isolation of tetranuclear ruthenium-carbonyl cluster compounds of the formula [Ru4(CO) 13(μ2-R2S)]. In these compounds, ruthenium atoms adopt a typical butterfly arrangement. If chelating ligands with two thioether functions are introduced, the reaction leads to mixtures of the trinuclear substitution products [Ru3(CO)10(RSSR)] and [Ru3(CO)8(RSSR)2]. The latter may be oxidatively cleaved by the use of chlorinated solvents to produce the mononuclear compound [Ru(CO)2Cl2(RSSR)] or the dinuclear complex [Ru2(CO)2(μ2-Cl)2Cl 2(RSSR)2] depending on the reaction conditions. Five new ruthenium-carbonyl-thioether complexes were characterized by X-ray diffraction. Irradiation of [Ru3(CO)12] in THF in the presence of thioether ligands yields ruthenium-carbonyl compounds [Ru4(CO) 13(μ2-R2S)] in the case of monodentate ligands, but [Ru3(CO)10(RSSR)] and [Ru3(CO) 8(RSSR)2] if bidentate thioether ligands are used. The latter may be oxidatively cleaved by CHCl3 to produce the dinuclear complex [Ru2(CO)2(μ2-Cl)2Cl 2(RSSR)2]. Copyright

Ligand-controlled regio- and stereoselective addition of carboxylic acids onto terminal alkynes catalyzed by carbonylruthenium(0) complexes

The addition of carboxylic acids onto terminal alkynes was catalyzed by mononuclear ruthenium(0) complexes to give enol esters in high yields. By using ligands with different electronic properties, product selectivity was achieved. E-enol esters were preferentially produced when tricarbonyl(η4- diene)ruthenium complexes were used; while geminal enol esters were produced when tricarbonylbis(phosphane)ruthenium complexes were used. Product selectivity is a major problem in transition metal-catalyzed hydrocarboxylation reactions. In this paper we report the ability of Ru(CO)3L2 (where L is a 2 e-donor) to catalyze the addition of variouscarboxylic acids onto terminal alkynes. A direct relationship between the regioselectivity of the product and the electronic property of the catalysis metal centre was observed.

The new bis(methimazolyl)silane PhSiH(mt)2 (mt = methimazolyl), obtained from methimazole (Hmt) and phenyldichlorosilane, reacts with [Ru(η4-C8H12)(η6-C 8H10)] in refiuxing tetra

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].

Heterobimetallic ruthenium-cobalt complexes containing the pentamethylcyclopentadienyl or indenyl ligand

The salt elimination reaction between NaCo(CO)4 and the ruthenium complexes LRu(diphos)Cl and [(Ind)Ru(CO)2Cl] afforded the Ru-Co bimetallic complexes [LRu(μ-CO)2(μ-diphos)Co(CO) 2] [L = C5Me5 (Cp*), diphos = Ph 2P(CH2)nPPh2, 3a: n = 1 , or 3b: n = 2; 3. L = C9H7 (Ind), diphos = Ph2PCH 2PPh2 ] and [(Ind)Ru(CO)2Co(CO)4] (3d), respectively, in high yields. However, the same reaction with the monophosphane analogue, [(Ind)Ru(PPh3)2Cl], gave the heterobimetallic complex [(Ind)Ru(PPh3)(CO)(μ-CO)Co(CO) 3] (3e) in fair yield, together with redox-initiated derivatives Ru(PPh3)2(CO)3 (4e) and [(Ind)Co(CO)(PPh 3)] (6e). A similar redox process in the reaction of the dppf analogue, [(Ind) Ru(dppf)Cl] (dppf = 1,1′-diphenylphosphanylferrocene) gave [Ru(dppf)(CO)3] (4f) and [(Ind)Co(CO)2] (6f), together with a complex salt [(Ind)Ru(dppf)(CO)][Co(CO4)] [5f·Co(CO)4].
