Low-Energy and Long-Lived Emission from Polypyridyl Ruthenium(II) Complexes Having A Stable-Radical Substituent

Novel polypyridyl ruthenium(II) complexes having a 2,2?-bipyridine (bpy) derivative which possesses a 1,5-dimethyl-6-oxoverdazyl radical (OV) group as a stable-radical substituent were designed and synthesized. The radical-ruthenium(II) complexes showed low-energy/intense MLCT absorption and low-energy/long-lived MLCT emission, and these characteristics of the complexes were explained by the electron-withdrawing nature of the OV group. Furthermore, the radical-substituent effects were enhanced by the presence of the electron-donating methyl groups at the 4- and 4?-positions of bpy in the ancillary ligands. The detailed electrochemical, spectroscopic, and photophysical properties of the complexes were discussed in terms of the systematic modification of the second coordination sphere in the main and ancillary ligands.

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.Recommanded Product: 15746-57-3, you can also check out more blogs about15746-57-3

Unique solubility of polyoxoniobate salts in methanol: Coordination to cations and POM methylation

Sodium salts of hybrid organometallic POM complexes consisting of [M6O19]8- (M = Nb, Ta) and half-sandwich fragments {Cp?M}2+ (Cp? = eta5-C5(CH3)5; M = Rh, Ir) and {(C6H6)Ru}2+ dissolve only in one organic solvent, that is, in methanol. From methanolic solutions, crystals of Na4[trans-{(C6H6)Ru}2Nb6O19]¡¤14.125MeOH¡¤2H2O (1), K4[trans-{Cp?Rh}2Nb6O19]¡¤4MeOH¡¤10H2O (2) and K4[trans-{Cp?Ir}2Nb6O19]¡¤10MeOH¡¤4H2O (3) were isolated and characterized by X-ray analysis. Methoxo species [{LM?}2M6O19-n(OCH3)n] (n = 1-3) were detected in solution by ESI-MS and NMR, and they account only for about half of the total speciation in the solution. DFT calculations were used to calculate 13C NMR chemical shifts in the methoxo complexes and to assess their relative stability. Reasons for the preferred solubility in methanol are discussed.

Synthesis, characterization and biological evaluation of cationic organoruthenium(ii) fluorene complexes: Influence of the nature of the counteranion

In this study, five ruthenium arene complexes with fluorene-bearing N,N-(1) and N,O-(2) donor Schiff base ligands were synthesized and fully characterized. Cationic ruthenium complexes 3[X], ([Ru(eta6-C6H6)(Cl)(fluorene-NCH-pyridine)][X] (where X = BF4, PF6, BPh4), were obtained by reacting ligand 1 with [Ru(eta6-C6H6)Cl2]2 in the presence of NH4X salts, whereas neutral complex 4, Ru(eta6-C6H6)(Cl)(fluorene-NCH-naphtholate), was isolated by reacting ligand 2 with the same precursor. It was possible to obtain a cationic version of the latter, 5[BF4], by reacting 4 with AgBF4 in the presence of pyridine. All compounds were fully characterized by NMR and HR-ESI-MS whereas some of them were also analyzed by single crystal X-ray analysis. Their in vitro antiproliferative activity was also assessed in human breast cancer cell lines, notably MCF-7 and T47D. Complex 4 and its cationic counterpart 5[BF4] were found to be the most cytotoxic compounds of the series (IC50 = 6.2-16.2 muM) and displayed higher antiproliferative activities than cisplatin in both cell lines. It was found that 5[BF4] undergoes a ligand exchange reaction and readily converts to 4 in the presence of 0.1 M NaCl, explaining the similarity in their observed cytotoxicities. Whereas 3[BF4] and 3[PF6] were found inactive at the tested concentrations, 3[BPh4] displayed a considerable cytotoxicity (IC50 = 16.7-27.8 muM). Notably, 3[BPh4], 4 (and 5[BF4]) were active against T47D, a cisplatin resistant cell line. Interestingly, 4 (16.4 muM) was found to be less cytotoxic than 3[BPh4] and cisplatin (6.6 and 7.9 muM, respectively) in breast healthy cells (MCF-12A). However, in comparison to 4 and cisplatin (at 10 muM), a lower in vivo toxicity was observed for complex 3[BPh4] on the development of zebrafish (Danio rerio) embryos.

Transfer hydrogenation of ketones and catalytic oxidation of alcohols with half-sandwich complexes of ruthenium(II) designed using benzene and tridentate (S, N, E) type ligands (E = S, Se, Te)

The complexes of composition fac-[(eta6-C6H 6)Ru(L)][PF6][X] (1-6; X = PF6 or Cl), formed by reacting 2-MeSC6H4CH=NCH2CH 2E-C6H4-4-R (L1-L3) and 2-MeSC 6H4CH2-NHCH2CH2E-C 6H4-4-R (L4-L6) (where E = S or Se, R = H; E = Te, R = OMe) with [{(eta6-C6H6)RuCl(mu-Cl)} 2] and NH4PF6, have been characterized by 1H, 13C{1H}, 77Se{1H}, and 125Te{1H} NMR spectroscopy and X-ray crystallography. The Ru-Se and Ru-Te bond lengths are in the ranges 2.4837(14)-2.4848(14) and 2.6234(6)-2.6333(7) A, respectively. Complexes 1-6 have been found to be efficient catalysts for catalytic oxidation of alcohols with N-methylmorpholine-N-oxide, tBuOOH, NaOCl, and NaIO4 and transfer hydrogenation reaction of ketones with 2-propanol. The TON values are up to 9.9 ¡Á 104 and 9.8 ¡Á 104 for two catalytic processes, respectively. The oxidation probably involves the formation of intermediate species having Ru(IV)=O. Complexes 1-3 are as efficient as 4-6 for transfer hydrogenation of ketones. In transfer hydrogenation, the mechanism does not appear to be dependent on the availability of hydrogen on nitrogen and probably involves Ru-H bond formation. The catalytic efficiency for both processes follows the order Te > Se > S, which may be due to the presence of a MeO group on Te.

Reactions of [{Ru(eta6-C10H14)Cl2}2] (eta6-C10H14=p-cymene H3C-C6H4-CH(CH3)2) with 4-cyanopyridine (referred hereafler as CNPy) in 1:1 and 1:2 molar ratios in dichloromethane yields the binuclear complex [{Ru(eta6-C10H14)Cl2} 2(mu-CNPy)] and the mononuclear complex [Ru(eta6-C10H14)Cl2(CNPy)]. The latter complex further reacts with [{Ru(eta6-C6Me6)Cl2}2] and [Ru(eta5-C5H5)(PPh3) 2Cl] to give 4-cyanopyridine bridged complexes [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(mu6-C6Me 6)Cl2] and [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(eta5-C5H 5)(PPh3)2]+. The complex [Ru(eta6-C10H14)Cl2(CNPy)] also undergoes metathetical reactions with EPh3 (E=P, As or Sb) to give complexes with the general formulations [Ru(eta6-C10H14)Cl2(EPh 3)], however its reaction with diphenylphosphinomethane (dppm) in a 1:1 ratio gives the mononuclear complex [Ru(eta6-C10H14)Cl2(dppm)] in which the dppm ligand is present in uncommon coordination mode (eta1-dppm). The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H-, 13C-, 31P-NMR). The structure of [Ru(eta6-C10H14)Cl2(CNPy)] [a=10.984(1), b=14.052(1), c=12.189(1) A; beta=114.810(1); V=1707.8(4) A3; Dcalc=1.596 g cm-3; monoclinic P21/c; Z=4] and confirmation of uncommon coordination mode of dppm, in [Ru(eta6-C10H14)Cl2(dppm)] [a=11.504(3), b=19.532(3), c=15.942(3) A; beta=96.08(2); V=3562(2) A3; Dcalc=1.446 g cm-3; monoclinic P21/n; Z=4] has been determined by X-ray crystallography.

Acceptorless and Base-free Dehydrogenation of Cyanohydrin with (eta6-Arene)halide(Bidentate Phosphine)ruthenium(II) Complex

Ruthenium-catalyzed dehydrogenation of cyanohydrins under acceptorless and base-free conditions was demonstrated for the first time in the synthesis of acyl cyanide. As opposed to the thermodynamically preferred elimination of hydrogen cyanide, the dehydrogenation of cyanohydrins could be kinetically controlled with ruthenium (II) bidentate phosphine complexes. The effects of the arene, phosphine ligands and counter anions were investigated in regard to catalytic activity and selectivity. Selective dehydrogenation can occur via beta-hydride elimination with the experimentally observed [(alkoxide)Ru] complex. (Figure presented.).

Ionic liquid based Ru(II)-phosphinite compounds and their catalytic use in transfer hydrogenation: X-ray structure of an ionic compound 1-chloro-3-(3-methylimidazolidin-1-yl)propan-2-ol

The compound 1-chloro-3-(3-methylimidazolidin-1-yl)propan-2-ol chloride (1) was prepared from the reaction of 1-methylimidazole with epichlorohydrine. The corresponding phosphinite ligands were synthesized by the reaction 1-chloro-3-(3-methylimidazolidin-1-yl)propan-2-ol chloride, [C7H 15N2OCl]Cl with one equivalent of chlorodiphenylphosphine or chlorodicyclohexylphosphine, in anhydrous CH2Cl2 and under an inert argon atmosphere.

The structures of these ligands and their corresponding complexes have been elucidated by a combination of multinuclear NMR and IR spectroscopy, TGA/DTA and elemental analysis. The molecular structure of the ionic compound 1 was also determined by an X-ray single crystal diffraction study. Furthermore, the catalytic activity of complexes 4-7 for the transfer hydrogenation of various ketones was investigated and these complexes were found to be efficient catalysts in the transfer hydrogenation of various ketones, with excellent conversions up to 99%.

Ruthenium(II) complexes bearing a naphthalimide fragment: A modular dye platform for the dye-sensitized solar cell

Cycloruthenated complexes of the type [RuII(N^N) 2(C^N)]+ (N^N = substituted 2,2?-bipyridine; C^N = substituted 3-(2?-pyridyl)-1,8-naphthalimide ligand) are shown to generate high power conversion efficiencies (PCEs) in the dye-sensitized solar cell (DSSC). It is shown that substitution of the pyridine ring of the C^N ligand with conjugated groups can enhance molar absorption extinction coefficients, while the electron density imparted on the metal center is alleviated by the 1,8-naphthalimide fragment. This latter feature maintains a Ru(III)/Ru(II) redox couple more positive than 0.8 V versus NHE, thereby accommodating regeneration of the oxidized dye by an iodide-based redox mediator. This dye platform can consequently be modulated at various sites to enhance light absorption and suppress recombination between the redox mediator and the TiO2 surface without compromising dye regeneration, thereby maintaining device PCEs as high as 7%. We also introduce a new phosphine-based coadsorbent, bis(2-ethylhexyl)phosphinic acid (BEPA), which is significantly easier to synthesize than the widely used bis(3,3-dimethylbutyl)phosphinic acid (DINHOP) while also facilitating high dye loading.
