Intramolecular Electron-Transfer of Covalently-Linked Polypyridine Ruthenium(II)Rhodium(III) Binuclear Complexes in the Excited State. Observation of the Marcus Inverted Region

Ru(II)bpy2Mebpy-CH2CH(OH)CH2-MebpyRh(III)L2 (L=bpy.phen) (1) were newly synthesized.Intramolecular electron-transfer in excited 1 was studied with a time-correlated single photon counting method.In H2O, the excited Ru(II) complex exhibits a biexponential decay.The presence of a slow component suggests that the excited state can be repopulated by thermal activation from the (Ru(III)-Rh(II) and the direct process to the ground state lies in the Marcus Inverted region.

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

Reactivity and electrochemical behavior of ruthenium dithiolene complexes with coordinatively unsaturated metal centers: Cycloaddition and dimerization reactions

The novel ruthenium dithiolene complexes [(arene)Ru{S2C 2(COOMe)2}] (arene = C6H6 (1a), C6H4(Me)(iPr) (1b), C6Me6 (1c)) were synthesized. The equilibrium between complex 1a and the corresponding dimer [(C6H6)Ru{S2C2(COOMe) 2}]2 (1a?) was confirmed in solution. The reaction of complex 1a with dimethyl- or diethylacetylene dicaboxylate gave the alkene-bridged adducts [(C6H6)Ru{S2C 2(COOMe)2}{C2(COOR)2}] (R = Me (2a), Et (3a)) as [2 + 2] cycloaddition products formally. The reactions of complex 1a with diazo compounds also gave the alkylidene-bridged adducts [(C 6H6)Ru{S2C2(COOMe) 2}(CHR)] (R = H (4a), SiMe3 (5a), COOEt (6a)) as [2 + 1] cycloaddition products. The electrochemical behavior of complex 1a was investigated. The reductant of complex 1a was a stable species for several minutes. The oxidant of complex 1a was very unstable; the cation 1a+ formed was immediately converted to the corresponding cationic dimer 1a?+. The cationic dimer 1a?+ was stable for several minutes, and it was rapidly and quantitatively converted to the neutral complex 1a when it was reduced.

Atropselective Dibrominations of a 1,1?-Disubstituted 2,2?-Biindolyl with Diverging Point-to-Axial Asymmetric Inductions. Deriving 2,2?-Biindolyl-3,3?-diphosphane Ligands for Asymmetric Catalysis

On the 1H NMR timescale, 2,2?-biindolyls with (R)-configured (1-alkoxyprop)-2-yl, (1-hydroxyprop)-2-yl, or (1-siloxyprop)-2-yl substituents at C-1 and C-1? are atropisomerically stable at <0 C and interconvert at >30 C. A 2,2?-biindolyl (R,R)-17 a of that kind and achiral (!) brominating reagents gave the atropisomerically stable 3,3?-dibromobiindolyls (M)- and/or (P)-18 a at best atropselectively?because of point-to-axial asymmetric inductions?and atropdivergently, exhibiting up to 95 % (M)- and as much (P)-atropselectivity. This route to atropisomerically pure biaryls is novel and should extend to other substrates and/or different functionalizations. The dibromobiindolyls (M)- and (P)-18 a furnished the biindolyldiphosphanes (M)- and (P)-14 without atropisomerization. These syntheses did not require the resolution of a racemic mixture, which distinguishes them from virtually all biaryldiphosphane syntheses known to date. (M)- and (P)-14 acted as ligands in catalytic asymmetric allylations and hydrogenations. Remarkably, the beta-ketoester rac-25 c was hydrogenated trans-selectively with 98 % ee; this included a dynamic kinetic resolution.

Hole tunneling and hopping in a Ru(bpy)32+- phenothiazine dyad with a bridge derived from oligo-p-phenylene

A molecular dyad was synthesized in which a Ru(bpy)3 2+ (bpy = 2,2?-bipyridine) photosensitizer and a phenothiazine redox partner are bridged by a sequence of tetramethoxybenzene, p-dimethoxybenzene, and p-xylene units. Hole transfer from the oxidized metal complex to the phenothiazine was triggered using a flash-quench technique and investigated by transient absorption spectroscopy. Optical spectroscopic and electrochemical experiments performed on a suitable reference molecule in addition to the above-mentioned dyad lead to the conclusion that hole transfer from Ru(bpy)33+ to phenothiazine proceeds through a sequence of hopping and tunneling steps: Initial hole hopping from Ru(bpy) 33+ to the easily oxidizable tetramethoxybenzene unit is followed by tunneling through the barrier imposed by the p-dimethoxybenzene and p-xylene spacers. The overall charge transfer proceeds with a time constant of 41 ns, which compares favorably to a time constant of 1835 ns associated with equidistant hole tunneling between the same donor-acceptor couple bridged by three identical p-xylene units. The combined hopping/tunneling sequence thus leads to an acceleration of hole transfer by roughly a factor of 50 when compared to a pure tunneling mechanism.

Arene-ruthenium(II) acylpyrazolonato complexes: Apoptosis-promoting effects on human cancer cells

A series of ruthenium(II) arene complexes with the 4-(biphenyl-4-carbonyl)- 3-methyl-1-phenyl-5-pyrazolonate ligand, and related 1,3,5-triaza-7- phosphaadamantane (PTA) derivatives, has been synthesized. The compounds have been characterized by NMR and IR spectroscopy, ESI mass spectrometry, elemental analysis, and X-ray crystallography. Antiproliferative activity in four human cancer cell lines was determined by MTT assay, yielding dose- and cancer cell line-dependent IC50 values of 9-34 muM for three hexamethylbenzene-ruthenium complexes, whereas the other metal complexes were much less active. Apoptosis was the mechanism involved in the anticancer activity of such compounds. In fact, the hexamethylbenzene-ruthenium complexes activated caspase activity, with consequent DNA fragmentation, accumulation of pro-apoptotic proteins (p27, p53, p89 PARP fragments), and the concomitant down-regulation of antiapoptotic protein Bcl-2. Biosensor-based binding studies indicated that the ancillary ligands were critical in determining the DNA binding affinities, and competition binding experiments further characterized the nature of the interaction.
