A new thiocyanate-free cyclometallated ruthenium complex for dye-sensitized solar cells: Beneficial effects of substitution on the cyclometallated ligand

A new thiocyanate-free cyclometallated 2-phenylpyridine Ru(II) complex, [Ru(dFppyCF3)(dcbpy)2]+PF6 – (dFppyCF3 = 2-(2,4-difluorophenyl)-5- trifluoromethyilpyridine; dcbpy = 2,2?-bipyridine-4,4?-dicarboxylic acid), containing an electronwithdrawing trifluoromethyl group on the pyridine ring of the cyclometallated ligand, was synthesized and used as photosensitizer in DSSC devices. Its optical and electrochemical properties and stability behaviour towards ligand exchange with the common solar cell additive 4-tert-butylpyridine was compared to that of benchmark DSSC dye N719 and of the reference complex [Ru(dFppy)(dcbpy)2]+PF6 -. Substitution of the pyridine ring by the CF3 group afforded enhanced optical properties and a larger overall power conversion efficiency of the corresponding DSSC (3.7%), with a significant improvement compared to the reference cyclometallated complex under the same fabrication conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C12H12Cl4Ru2, you can also check out more blogs about37366-09-9

Synthesis and characterization of tetrahedral Ru3O clusters with intrinsic framework chirality: A chiral probe of the intact cluster catalysis concept

To bring evidence for or against the hypothesis of catalytic hydrogenation by intact trinuclear arene ruthenium clusters containing an oxo cap, cationic Ru3O clusters with three different arene ligands (intrinsically chiral tetrahedra) have been synthesized as racemic mixtures. By introduction of a chiral auxiliary substituent at one of the three different arene ligands, the separation of the two diastereomers was possible. The chiral Ru3O framework was evidenced by X-ray crystallography, by circular dichroism in the UV and IR regions, and by chiral shift reagents in the NMR spectra. The catalytic hydrogenation of the prochiral substrate methyl 2-acetamidoacrylate using a chiral Ru3O cluster showed no asymmetric induction, suggesting that the catalytically active species is not the intact Ru3O cluster.

pH-Dependent competition between K2N7,O(P) macrochelation and mu-N1,N7 oligomer formation for (eta6-arene)RuII complexes of adenosine and guanosine 5?-mono-, -di- and -tri-phosphates

The pH-dependent reaction of [Ru(eta6-C6H6)(D2O) 3]2+ with adenosine and guanosine 5?-mono-, -di- and -tri-phosphates has been studied by 1H and 31P-{1H} NMR spectroscopy. Diastereomeric mu-1kappaN1:2kappa2N6,N7 co-ordinated cyclic trimers of the type [{Ru(5?-AMP)(eta6-C6H6)}3] predominate for adenosine 5?-monophosphate (5?-AMP2-) in the range pH* 3.30-9.18. An X-ray structural analysis of the Ru5Ru5Ru5 diastereomer [{Ru-(?-AMP)(eta6-p-MeC6H4Pr i)}3]¡¤7.5H2O 1b established a pronounced degree of conformational flexibility in the sugar and phosphate residues. In contrast to 5?-AMP2-, cyclic trimers cannot be observed in more strongly acid solution (pH* ? 3.16) for the equilibrium system 5?-ATP-(eta6-C6H6)RuII (5?-ATP4- = adenosine 5?-triphosphate) and remain relatively minor species even at neutral or higher pH* values. As confirmed by pronounced low-field 31P-{1H} NMR shifts of up to 7.8 and 8.6 ppm for the beta- and gamma-phosphorus atoms, kappa3N7, O(P beta), O(Pgamma) macrochelates provide the dominant metal species in acid solution. Time-dependent NMR studies for 5?-ADP-(eta6-C6H6)RuII (5?-ADP3- = adenosine 5?-diphosphate) indicated that initial macrochelation of this nucleotide is followed by cleavage of the beta-phosphate group and formation of cyclic trimers of 5?-AMP2-. Reaction of guanosine 5?-monophosphate (5?-GMP2-) with [Ru(eta6-C6H6)(D2O) 3]2+ afforded kappaN7-co-ordinated 1:1 and 2:1 complexes in the range pH* 3.69-8.38. In addition to analogous 1:1 and 2:1 species, kappa3N7, O(Pbeta), O(Pgamma) macrochelates are observed for the 5?-GTP-(eta6-C6H6)RuII equilibrium system (5?-GTP4- = guanosine 5?-triphosphate) in acid solution. Initial macrochelation in the 5?-GDP-(eta6-C6H6)RuII system (5?-GDP3- = guanosine 5?-diphosphate) again leads to rapid cleavage of the terminal beta-phosphate function.

Arene-ruthenium(II) complexes containing inexpensive tris(dimethylamino) phosphine: Highly efficient catalysts for the selective hydration of nitriles into amides

The catalytic hydration of nitriles into amides, in water under neutral conditions, has been studied using a series of arene-ruthenium(II) derivatives containing the commercially available and inexpensive ligand tris(dimethylamino)phosphine. Among them, best results were obtained with the complex [RuCl2(eta6-C6Me6) {P(NMe2)3}], which selectively provided the desired amides in excellent yields and short times (TOF values up to 11 400 h-1). The process was operative with both aromatic, heteroaromatic, aliphatic, and alpha,beta-unsaturated organonitriles and showed a high functional group tolerance. The stability of [RuCl2(eta6-C 6Me6){P(NMe2)3}] in water was evaluated, observing its progressive decomposition into the less-active dimethylamine-ruthenium(II) complex [RuCl2(eta6-C 6Me6)(NHMe2)] by hydrolysis of the coordinated P(NMe2)3 ligand. The X-ray crystal structure determination of the toluene complex [RuCl2(eta6-C6H 5Me){P(NMe2)3}] is also included.

Chiral salicyloxazolines as auxiliaries for the asymmetric synthesis of ruthenium polypyridyl complexes

Chiral auxiliaries are promising emerging tools for the asymmetric synthesis of octahedral metal complexes. We recently introduced chiral salicyloxazolines as coordinating bidentate chiral ligands which provide excellent control over the metal-centered configuration in the course of ligand substitution reactions and can be removed afterward in an acid-induced fashion under complete retention of configuration (J. Am. Chem. Soc. 2009, 131, 9602-9603). Here reported is our detailed investigation of this sequence of reactions, affording virtually enantiopure ruthenium polypyridyl complexes. The control of the metal-centered chirality by the coordinated chiral salicyloxazolinate ligand was evaluated as a function of reaction conditions, the employed bidentate 2,2?-bipyridine and 1,10-phenanthroline ligands, and the substituent at the asymmetric 5-position of the oxazoline heterocycle. Most striking was the strong influence of the reaction solvent, with aprotic solvents of lower polarity providing the most favorable diastereoselectivities. Through a combination of computational and experimental results, it was revealed that the observed stereoselectivities are under thermodynamic control. The removal of the chiral salicyloxazoline auxiliary under retention of the configuration requires acidic conditions and a coordinating solvent such as MeCN or THF in order to prevent partial racemization. This method represents the first general strategy for the asymmetric synthesis of enantiopure heteroleptic ruthenium polypyridyl complexes.

Nanosecond transient absorption spectroscopy of a Ru polypyridine phenothiazine dyad

A bipyridine phenothiazine ligand [(PTZEtv2bpy) and metal complexes [Ru(Ph2phen)3]2+(1), [(Ph2phen)2Ru(PTZEtv2bpy)]2+(2), and [(PTZEtv2bpy)(Ph2phen)Ru(dpp)]2+(3) were synthesized and characterized, where Ph2phen is 4,7-diphenyl-1,10-phenanthroline, dpp is 2,3-bis(2-pyridyl)pyrazine and PTZEtv2bpy is 4,4? ethylene bridged phenothiazine 2,2?bipyridine. The reduction potentials of PTZEtv2bpy, 1, 2, and 3 were determined by cyclic and square wave voltammetric methods. The absorbance and emission spectra of complexes 2 and 3 yield intense, visible Metal-to-Ligand Charge Transfer (MLCT) transitions. The nanosecond transient absorption data indicate formation of both the3MLCT state and a ligand localized3PTZ state.
