Synthesis, characterization, and photochemical behavior of {Ru(arene)} 2+ derivatives of alpha-[PW11O39] 7-: An organometallic way to ruthenium-substituted heteropolytungstates

Reaction of [Ru(arene)Cl2]2 (arene = benzene, toluene, p-cymene, hexamethylbenzene) with K7[PW11O 39]¡¤14H2O provided two series of organometallic derivatives of heteropolytungstates: type-1 and type-2 complexes of general formulas [PW11O39{Ru(arene)(H2O)}]5- and [{PW11O39{Ru(arene)}}2{WO 2}]8-, respectively. All compounds were characterized by infrared and multinuclear NMR (1H, 31P, 183W) spectroscopies. The crystal structures of Na4K4-[{PW 11O39{Ru(benzene)}}2{WO2}] ¡¤6H2O (NaK-2a¡¤6H2O), K7H[{PW 11O39{Ru(toluene)}}2{WO2}] ¡¤4H2O (K-2b¡¤4H2O), and Cs3K 2[PW11O39{Ru(p-cymene)(H2O)}] ¡¤4H2O (CsK-1c-4H2O) were obtained and revealed that the {Ru(arene)} fragment is supported on the oxometallic framework. Photochemical reactivity of [PW11O39{Ru(arene)(H 2O)}]5- (arene = toluene, p-cymene) in the presence of various ligands L (L = H2O, dimethyl sulfoxide, tetramethylene sulfoxide, and diphenyl sulfoxide) was investigated, and led to the formation of [PW11O39{Ru(L)}]5-, in which the ruthenium is incorporated into the lacunary [PW11O39]7- anion.

Kinetics and Mechanism of the Stereochemical Isomerization of an Arene-Ruthenium Complex of the Atropisomeric Ligand 1,1?-Biphenyl-2,2?-diamine

(eta 6-Benzene)(delta/lambda-1,1?-biphenyl-2,2?-diamine) chlorometal(II) hexafluorophosphate (1; metal = ruthenium, osmium) have been synthesized. The rigid nature of the seven-membered chelate ring formed by the 1,1?-biphenyl-2,2?-diamine (dabp) ligand renders the complexes chiral. The resulting C1 molecular symmetry of 1(M=Ru) that we have observed in the solid state by single-crystal X-ray crystallography is preserved in solution on the NMR time scale. The four N-H protons of 1(M=Ru,Os) are chemically inequivalent in the 1H NMR spectrum at 20C. Spin-perturbation NMR experiments in acetone solutions reveal pairwise exchange of the resonances that correspond to the N-H protons on the spin-relaxation time scale. The three mechanisms that would account for such an exchange (atropisomerization of the dabp ligand, inversion of stereochemistry at the metal center, and simultaneous inversion of the stereochemistry at the metal and the ligand) are distinguishable, provided a proper assignment of the four N-H protons can be made in the NMR spectra. Having made that assignment, we conclude from 2D EXSY NMR spectroscopy that the mechanism of exchange is inversion of stereochemistry at the dabp ligand center. This observation contrasts with previous reports that conformational isomers of dabp can be resolved.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Recommanded Product: 37366-09-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 37366-09-9, in my other articles.

Selective Photoinactivation of Methicillin-Resistant Staphylococcus aureus by Highly Positively Charged RuII Complexes

Cyclometalated Ruthenium Catalyst Enables Ortho-Selective C?H Alkylation with Secondary Alkyl Bromides

Although Ru-catalyzed meta-selective sp2 C?H alkylation with secondary alkyl halides is well established, ortho selectivity has never been achieved. We demonstrate that the use of a cyclometalated Ru-complex, RuBnN, as the catalyst results in a complete switch of the inherent meta-selectivity to ortho selectivity in the Ru-catalyzed sp2 C?H alkylation reaction with unactivated secondary alkyl halides. The high catalytic activity of RuBnN allows mild reaction conditions that result in a transformation of broad scope and versatility. Preliminary mechanistic studies suggest that a bis-cycloruthenated species is the key intermediate undergoing oxidative addition with the alkyl bromides, thus avoiding the more common SET pathway associated with meta-selectivity. Direct C?H functionalization is a powerful tool for milder and more environmentally friendly syntheses of biologically active compounds, as well as offering easy access to unexplored chemical space in drug discovery. However, major challenges remain for these methods to be widely applicable. The development of new catalysts with diverse and superior reactivity is key to address these challenges. Here, we show for the first time that cyclometalated Ru-complexes are able to catalyze the directed ortho-C?H alkylation of arenes with secondary alkyl bromides, enabling the late-stage functionalization and diversification of pharmaceuticals. The obtained regioselectivity is in stark contrast to that delivered by the commonly used arene-bound Ru-complexes, which afford exclusive meta-alkylation. Our work points a way to further rationally design next-generation Ru-catalysts with improved control over selectivity and reactivity, and a richer synthetic toolbox for chemists in the future. Here, we report the first ortho-selective sp2 C?H bond alkylation with secondary alkyl bromides in the Ru catalytic platform, enabled by cyclometalated ruthenium(II) complex RuBnN. Mechanistic studies indicate that the formation of a bis-cycloruthenated intermediate enables an oxidative addition to occur, thus avoiding the single-electron transfer (SET) pathway associated with meta-selectivity in other Ru catalytic systems. The reaction is tolerant of a variety of medicinally relevant functional groups and has been used to modify existing pharmaceuticals.

Redox chemistry and electronic properties of 2,3,5,6-tetrakis(2-pyridyl) pyrazine-bridged diruthenium complexes controlled by N.C.N-biscyclometalated ligands

To investigate the consequences of cyclometalation for electronic communication in dinuclear ruthenium complexes, a series of 2,3,5,6-tetrakis(2- pyridyl)pyrazine (tppz) bridged diruthenium complexes was prepared and studied. These complexes have a central tppz ligand bridging via nitrogen-to-ruthenium coordination bonds, while each ruthenium atom also binds either a monoanionic, N, C, N-terdentate 2,6-bis(2-pyridyl)phenyl (R-N-C-N) ligand or a 2,2I:6I, 2II-terpyridine (tpy) ligand. The N, C, NI-, that is, biscyclometalation, instead of the latter N, NI, NII-bonding motif significantly changes the electronic properties of the resulting complexes. Starting from well-known [{Ru(tpy)}2(mu-tppz)]4+ (tpy = 2,2I:2 II, 6-terpyridine) ([3]4+) as a model compound, the complexes [{Ru(R-N-C-N)}(mu-tppz){Ru(tpy)}]3+ (R-N-C(H)-N = 4-R-1,3-dipyridylben-zene, R = H ([4a] 3+), CO2Me ([4b]3+)), and [{Ru(R-N -C-N)}2(mu-tppz)]2+, (R = H ([5a]2+), CO2Me ([5b]2+)) were prepared with one or two N, C, NI-cyclometalated terminal ligands. The oxidation and reduction potentials of cyclometalated [4]3+ and [5]2+ are shifted negatively compared to non-cyclometalated [3]4+, the oxidation processes being affected more significantly. Compared to [3] 4+, the electronic spectra of [5]2+ display large bathochromic shifts of the main MLCT transitions in the visible spectral region with low-energy absorptions tailing down to the NIR region. One-electron oxidation of [3]4+ and [5]2+ gives rise to low-energy absorption bands. The comproportionation constants and NIR band shape correspond to delocalized Robin-Day class III compounds. Complexes [4a]3+ (R = H) and [4b]3+ (R = CO2Me) also exhibit strong electronic communication, and notwithstanding the large redox-asymmetry the visible metal-to-ligand charge-transfer absorption is assigned to originate from both metal centers. The potential of the first, ruthenium-based, reversible oxidation process is strongly negatively shifted. On the contrary, the second oxidation is irreversible and cyclometalated ligand-based. Upon one-electron oxidation, a weak and low-energy absorption arises.

Condensation of 3-aminopropyltrimethoxysilane and chlorodiphenylphosphine in the molar ratio of 1:1 and 1:2 in the presence of Et3N in toluene afforded aminophosphine (CH3O)3Si(CH2)3NHPPh2 (L1) and bisphosphinoamine (CH3O)3Si(CH2)3N(PPh2)2 (L2) with methoxysilyl groups, respectively.

Reaction of [(eta6-p-cymene)RuCl2]2 with L2 under the similar condition gave a dinuclear ruthenium phosphine complex [(eta6-p-cymene)Ru(mu-Cl)3RuCl(kappa2-P,P-L2)] (2). Complexes 1 and 2 were characterized by microanalyses, IR and NMR spectroscopies, and their structures were also established by single-crystal X-ray diffraction. Immobilization of complexes 1 and 2 on SBA-15, and characterization of these hybrid heterogeneous catalysts were studied by transmission electron microscopy (TEM), IR and low pressure N2 adsorption/desorption measurement. The heterogeneous catalysts were also briefly tested for transfer hydrogenation of acetophenone.
