Oligomeric (eta6-arene) ruthenium(II) complexes of adenine and adenosine with N6,N7 coordination

Treatment of [{RuCl2(eta6-arene)}2] (arene=p-cymene, C6H6) with adenine (adeH), 9-ethyladenine (9etade) and adenosine (aden) provides the complexes [{Ru(ade) (eta6-p-cymene)}4] (CF3SO3)4 (2), [{Ru(9etadeH_1) (eta6-p-cymene)}3] (CF3SO3)3 (3) and [{Ru(adenH_1) (eta6-C6H6)}3] (CF3SO3)3 (4). The structures of complexes 2 and 3 were established by X-ray structural analysis. 2 crystallises in the tetragonal space group I41/a with a=b=15.870(2), c=35.710(7) A, Z=4; 3 ¡¤ 1.5H2O in the monoclinic space group C2/c with a=35.985(3), b=13.094(2), c=28.406(3) A, Z=8. Common to 2-4 is the participation of N6 and N7 in a five-membered chelate ring, which leads to a characteristic upfield shift in the 1H NMR signal of the pyrimidine proton H2. The tetrameric complex 2 exhibits the mu-1kappaN9:2kappa2N6,N7 coordination mode for the bridging adeninate ligands, the trimeric complexes 3 and 4 the mu-1kappaN1:2kappa2N6,N7 mode for the 9-substituted derivatives.

Synthetic routes to a coordinatively unsaturated ruthenium complex supported by a tripodal, protic bis(N-heterocyclic carbene) phosphine ligand

A facile, one pot synthesis of a coordinatively unsaturated ruthenium complex supported by a tripodal, protic bis(N-heterocyclic carbene) phosphine ligand is presented. A number of coordination complexes were discovered en route during this synthesis, revealing some of the unique aspects of complexes ligated by this type of tridentate, protic bis(NHC) ligand. Through a combination of 1D and 2D NMR spectroscopic analysis and single crystal X-ray diffraction, we reveal the intermediacy of phosphine-ligated bisimidazole complexes and show that abstraction of inner-sphere halide ions facilitates conversion to the desired tridentate bis(NHC) coordination mode. Ultimately the use of N-methyl-2-pyrrolidone is shown to enable the use of the extreme temperatures needed to facilitate the direct, thermally activated tautomerization reaction that gives rise to the bis(NHC) motif.

Controlled formation of mixed-metal macrocycles using dynamic exchange processes and steric constraints

The exchange reaction of the trinuclear macrocycles [(C6H 3iPr3)Ru(C5H3NO2)] 3 (AAA) and [(cymene)Ru(C5H3NO 2)]3 (BBB) has been studied. It was found that the equilibration proceeds in two steps and that the final mixture is completely dominated by the mixed-metal macrocycles [{(C6H3iPr 3)Ru}2{(cymene)Ru}(C5H3NO 2)3] (AAB) and [{(C6H3iPr 3)Ru}{(cymene)Ru}2(C5H3NO 2)3] (ABB). The results are rationalized by assuming unfavorable steric interactions between adjacent (C6H 3iPr3)Ru fragments. It is shown that interactions of this kind can be used to bias scrambling processes in such a way that mixed-metal macrocycles are obtained in over 80 % yield. The structures of [{(C 6Me6)Ru){(C6H6)Ru} 2(C5H3NO2)3] and [(Cp*Rh){(C6H6)Ru}2(C5H 3NO2)3] have been determined by single-crystal X-ray analysis. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Highly selective metathesis of 1-octene in ionic liquids

The self-metathesis of 1-octene to form 7-tetradecene catalyzed by ruthenium carbene complexes at low concentrations (0.02 mol %) was investigated in ionic liquids as reaction media and as additives. The study showed that the ionic liquid has a significant effect on the selectivity of the metathesis of 1-octene, with conversion to product of greater than 95% being obtained and selectivities of over 98% being realized. The outcomes of the reactions compared well with those performed under solventless conditions, showing improved conversions and selectivittes.

Substituted pyridazines as ligands in homoleptic (fac and mer) and heteroleptic Ru(ii) complexes

This article reports the preparation of a range of phenyl, pyridyl and pyrazinyl substituted pyridazines via the inverse electron demand [2 + 4] Diels-Alder reaction between 3,6-di(2-pyridyl)-1,2,4,5-tetrazines (bptz) and 3,6-di(2-pyrazinyl)-1,2,4,5-tetrazines (bpztz) and suitable dienophiles including acenaphthalene. The resulting polyaromatic compounds vary systematically in the number of aromatic substituents and the number and position of N-heteroatoms. For four of these compounds, the effect of the molecular changes on the solid-state structures were investigated using single crystal X-ray crystallography. The pyridazines were used as bidentate ligands in {M(ii)(bipy)2} and tris(homoleptic) complexes (M = Fe, Ru). The optical and electrochemical properties of these complexes reflect the electron accepting character of the new ligands. The facial and meridional isomers of the tris complexes could be separated by column chromatography (on silica), thus allowing a spectral comparison of their absorption and emission properties. The solid-state structures of several of the metal complexes are discussed, including that of the facial isomer of the tris Ru(ii) complex of 3,6-bis(2-pyridyl)-4,5-bis(4-pyridyl)pyridazine – a potential preformed geometric motif for the predirected construction of supramolecular assemblies.

Ruthenium(ll) complexes incorporating 2-(2?-Pyridyl)pyrimidine-4- carboxylic acid

A new bidentate ligand bearing a single carboxylate functionality, 2-(2?-pyridyl)pyrimidine-4-carboxylic acid (cppH), has been prepared and applied in the synthesis of a series of ruthenium(ll) complexes. Reaction of this new ligand with RuII(bpy)2CI2 led to the unexpected oxidation of the starting material to give [RuIII(bpy) 2CI2]CI ¡¤ H2O and a low yield of [RuII(bpy)2(cppH)](PF6)2 ¡¤ H2O (1) on addition of an aqueous KPF6 solution (bpy = 2,2?-bipyridine and cpp = 4-carboxylate-2?-pyridyl-2-pyrimidine). An X-ray crystal structure determination on crystals of 1a, [Ru II(bpy)2(cpp)](PF6), obtained from slow evaporation of an aqueous solution of 1 revealed that the nitrogen para to the carboxylate group in the cpp- ligand coordinates to the ruthenium(ll) center rather than that ortho to this group. The same complex was prepared via decarbonylation of [RuII(cppH)(CO)2CI2] ¡¤ H2O in the presence of bpy and an excess of trimethylamine-N-oxide (Me3NO), as the decarbonylation agent. The coordination of cppH in the precursor is the same as in the final product. The related complex [RuII(phen)2(cppH)](PF6) 2 ¡¤ 2H2O (2) (phen = 1,10-phenanthroline) was similarly synthesized. [RuII(bpy)(dppz)(cppH)](PF6) 2 ¡¤ CH3CN (3) (dppz = dipyrido[3,2,- a;2?,3-c]phenazine) was also prepared by photochemical decarbonylation of [RuII(bpy)(CO)2CI2] giving [Ru II(bpy)- (CO)CI2]2 followed by bridge splitting with dppz to generate [RuII(bpy)(dppz)(CO)CI](PF6) ¡¤ H2O. This intermediate was then reacted with cppH to produce 3, as a mixture of geometric isomers. In contrast to 1, X-ray crystallography on the major product isolated from this mixture, [RuII(bpy)(dppz) (cpp)](NO3) ¡¤ 10H2O, 3N3 indicated that the nitrogen adjacent to the carboxylate was coordinated to ruthenium(ll). Full characterization of these complexes has been undertaken including the measurement of UV-visible and emission spectra. Electrochemical and spectroelectro-chemical studies in acetonitrile show that these complexes undergo reversible oxidation from RuII to RuIII at potentials of 983 ¡À 3 mV, 1004 ¡À 5 mV, and 1023 ¡À 3 mV versus Fc0/+ (Fc = Ferrocene) for 1, 2, and 3N3, respectively.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 15746-57-3 is helpful to your research., Synthetic Route of 15746-57-3
