Synthesis and characterization of eta6-arene ruthenium complexes bearing oxopentadienyl and phosphine ligands

An addition reaction of dinuclear [(eta6-C6Me 6)Ru(eta3, 1-exo-syn-CH2CHCHCHO)] 2(BF4)2 (1) with different Lewis bases in acetone results in the formation of mononuclear [(eta6-C 6Me6)Ru(eta3-exo-syn-CH2CHCHCHO) (L)](BF4) (L = PMe3, 2; PPh3, 3; PHPh 2, 4; Ph2PEtPy, 6; CO, 7) and dinuclear [{(eta6-C6Me6)Ru(eta3-exo-syn- CH2CHCHCHO)}2(mu2-dppe)](BF4) 2 (5). The addition of Ph2PCH2CH 2PPh2 to the dinuclear product 1 affords 5 which show a bridging phosphine between two ruthenium centers. A comparative study of the new cationic arene derivatives and the corresponding isoelectronic Cp*Ru(heteropentadienyl) is established. All compounds were characterized by IR spectroscopy, high resolution mass spectrometry, NMR spectroscopy and the crystal structures of 2 and 3 are also described. Copyright

Convenient synthesis of tris-heteroleptic ruthenium(II) polypyridyl complexes

A convenient synthesis of tris-heteroleptic polypyridyl [Ru(pp)(pp?)(pp?)]2+ complexes is reported (where pp,pp?, and pp? represent three different polypyridyl ligands). Photolysis of [BzRu(pp)Cl]Cl (Bz = eta6-C6H6) gives a mixture of Ru(pp)(CH3CN)2Cl2 and [Ru(pp)(CH3CN)3Cl]Cl. Refluxing this mixture with pp? yields Ru(pp)(pp?)Cl2. Finally, refluxing Ru(pp)(pp?)Cl2 with pp? in a 75% ethanol/water solution gives [Ru(pp)(pp?)(pp?)]2+. No ligand scrambling is observed. The complexes are characterized by 1H NMR, elemental analysis, FAB-MB, UV-vis and emission spectroscopy, and cyclic voltammetry.

Aarene platinum group metal complexes containing imino-quinolyl ligands: synthesis and antibacterial studies

Imino-quinolyl Schiff-base ligands have been prepared by the condensation reaction of substituted 2-aminopyridine and quinoline-2-carbaldehyde. The reaction of [(arene)MCl2]2 with imino-quinolyl Schiff-base ligands leads to the formation of cationic complexes [(arene)M(L)Cl]+ (1?12). Single crystal X-ray diffraction studies were used to confirm the coordination mode and structures of these complexes. The molecular structures of these complexes revealed that they adopt characteristic three-legged piano stool geometry with the metal coordinating through a terminal chloride and imino-quinolyl ligands in a bidentate chelating NN? fashion. The ligand coordinates to the metal center through the nitrogen of the quinoline and the imine nitrogen forming a five-membered metallacycle. These compounds were evaluated for their in?vitro antibacterial activity by the agar well diffusion method against Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae strains. Results show that all the ligands and complexes inhibited the growth of bacteria.

Organometallic complexes supported on a metal-oxide cluster. pH-dependent interconversion between the monomeric and dimeric species of the polyoxoanion-supported [(arene)Ru]2+ complex

Keggin polyoxometalate (POM)-supported two (arene)Ru2+ complexes, i.e., the monomeric species (type-m) [{(arene)Ru(H 2O)}PW11O39]5- and the dimeric species (type-d) [({(arene)Ru}PW11O39)2(mu- WO2)]8-, were prepared as water-soluble Et 2NH2+ salts by pH-controlled reactions in aqueous solutions of the in situ-generated, mono-lacunary Keggin POM [PW 11O39]7- with the organometallic precursor [{RuCl2(arene)}2]. The effects of the arene (benzene (1), toluene (2), p-cymene (3), and hexamethylbenzene (4)) on the proportion of the type-m to type-d complex produced were examined. pH-Varied 31PNMR spectroscopy showed that there was a pH-dependent interconversion between type-m and type-d complexes, i.e., the ratio of the dimeric species increased as pH of the solution was lowered. Under the reaction conditions, the dimeric species d1, d3, and d4 as water-soluble Et2NH2+ salts were successfully isolated as the major products. It was concluded that (1) steric repulsion between the two (arene)Ru2+ fragments in the dimeric species was not significant, (2) the proportion was strongly dependent on the pH of the solution rather than the bulkiness of the arene, and (3) the use of the in situ-generated [PW11O39]7-, but not the isolated lacunary species, such as K7[PW11O 39]¡¤nH2O, had an effect on the reaction.

Half-sandwich ruthenium, rhodium and iridium complexes of triazolopyridine ligand: Synthesis and structural studies

Triazolopyridine ligand, {3-(2-pyridyl)-[1,2,3]triazolo[1,5-a]-pyridine}, L was synthesized by reaction of p-toulenesulphonyl hydrazine and dipyridyl ketone in the presence of acetic acid. Half-sandwich ruthenium, rhodium and iridium complexes [1?4] have been synthesized by reaction of [{(arene)MCl 2} 2] (arene = p-cymene/benzene/Cp* and M = Ru/Rh/Ir) with ligand L in methanol. The reaction in 1:2 (M:L) ratio has yielded all mononuclear cationic complexes such as [(arene)MLkappaN?N2Cl]PF 6, where {(arene)M} = (p-cym)Ru (1), (benz)Ru (2), Cp*Rh (3) and Cp*Ir (4). All the complexes were characterized by spectral studies and the solid state structures of complexes, 1 and 3 were unambiguously determined by crystallographic studies.

Organoruthenium(II) Complexes Bearing an Aromatase Inhibitor: Synthesis, Characterization, in Vitro Biological Activity and in Vivo Toxicity in Zebrafish Embryos

Third-generation aromatase inhibitors such as anastrozole (ATZ) and letrozole (LTZ) are widely used to treat estrogen receptor-positive (ER+) breast cancers in postmenopausal women. Investigating their ability to coordinate metals could lead to the emergence of a new category of anticancer drug candidates with a broader spectrum of pharmacological activities. In this study, a series of ruthenium(II) arene complexes bearing the aromatase inhibitor anastrozole was synthesized and characterized. Among these complexes, [Ru(?6-C6H6)(PPh3)(?1-ATZ)Cl]BPh4 (3) was found to be the most stable in cell culture media, to lead to the highest cellular uptake and in vitro cytotoxicity in two ER+ human breast cancer cell lines (MCF7 and T47D), and to induce a decrease in aromatase activity in H295R cells. Exposure of zebrafish embryos to complex 3 (12.5 muM) did not lead to noticeable signs of toxicity over 96 h, making it a suitable candidate for further in vivo investigations.

Synthesis and crystal structure of pseudo-sandwich-type heteropolytungstates functionalized by organometallic ruthenium(ii)

The reaction between [XW9O34]9- (X = As, P) and [RuC6H6Cl2]2 in aqueous buffer solution (pH 6.0) leads to the isolation of two pseudo-sandwich-type heteropolytungstates KNa6[(RuC6H6)AsW 9O34]¡¤17H2O (As-1) and Na 7[(RuC6H6)PW9O34] ¡¤14H2O (P-2). Single-crystal X-ray diffraction analyses reveal that the two compounds have the following features: (1) in two polyanions [(RuC6H6)XW9O34]7- (X = As, 1; P, 2), the (RuC6H6) unit is linked via three Ru-O(W) bridges to the side of the trilacunary polyanion, while the lacunary site is still free; (2) the units 1 and 2 are connected exclusively by a central Na cation cluster to form the pseudo-sandwich-type heteropolytungstates; and (3) the pseudo-sandwich-type heteropolytungstates are further connected by Na or K cations to construct the 2D and 3D structures. Furthermore, the electrochemical behaviours of As-1 and P-2 in aqueous solution (1.0 M LiCl + HCl, pH 3.0) have been investigated. Two compounds exhibit the expected reduction processes of the W atoms in a negative potential range and the oxidation of the Ru center in a positive potential range. The results of the electrocatalytic experiments reveal that the compound P-2 has electrocatalytic activity towards the reduction of nitrate.

Study of complexes of platinum group metals containing nitrogen bases derived from pyridine aldehydes: Interesting molecular structures with unpredicted bonding modes of the ligands

A series of mono-cationic dinuclear half sandwich ruthenium, rhodium and iridium metal complexes have been synthesized using ((pyridin-2-yl)methylimino) nicotinamide (L1) and ((picolinamido)phenyl)picolinamide (L2) ligands: [(eta6-arene)2Ru2(mu-L1)Cl 3]+ (arene = C6H6, 1; p- iPrC6H4Me, 2; C6Me6, 3), [(eta5-C5Me5)2M 2(mu-L1)Cl3]+ (M = Rh, 4; Ir, 5), and [(eta6-arene)2Ru2(mu-L2)(mu-Cl)] + (arene = C6H6, 6; p-iPrC 6H4Me, 7; C6Me6, 8), [(eta5-C5Me5)2M 2(mu-L2)Cl2]+ (M = Rh, 9; Ir, 10). All the complexes have been isolated as their hexafluorophosphate salts and fully characterized by use of a combination of NMR and IR spectroscopy. The solid state structure of three representatives 4, 6 and 9 has been determined by X-ray crystallographic studies. Interestingly, in the molecular structure of 4, the first metal is bonded to two nitrogen atoms whereas the second metal center is coordinated to only one nitrogen atom with two terminal chloride ligands. Fascinatingly in the case of the complexes with the symmetrical ligand L2, both ruthenium centers having eta6-arene groups are bonded to nitrogen atoms with a bridging chloride atom between the two metal centers, whereas the metals with eta5-Cp groups are bonded to the ligand N,O and N,N fashion.

Bis(allyl)-ruthenium(IV) complexes as highly efficient catalysts for the redox isomerization of allylic alcohols into carbonyl compounds in organic and aqueous media: Scope, limitations, and theoretical analysis of the mechanism

The catalytic activity of the bis(allyl)-ruthenium(IV) dimer [{Ru(eta3:eta3-C10H16)(mu-Cl) Cl}2] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8- diyl) (1), and that of its mononuclear derivatives [Ru(eta3: eta3-C10H16)Cl2(L)] (L = CO, PR3, CNR, NCR) (2) and [Ru(eta3:eta3-C 10H16)Cl(NCMe)2][SbF6] (3), in the redox isomerization of allylic alcohols into carbonyl compounds, both in tetrahydrofuran and in water, is reported. In particular, a variety of allylic alcohols have been quantitatively isomerized using [{Ru(eta3: eta3-C10H16)(mu-Cl)Cl}2] (1) as catalyst, the reactions proceeding in all cases faster in water. Remarkably, complex 1 has been found to be the most efficient catalyst reported to date for this particular transformation, leading to TOF and TON values up to 62 500 h-1 and 1 500 000, respectively. Moreover, catalyst 1 can be recycled and is capable of performing allylic alcohol isomerizations even in the presence of conjugated dienes, which are known to be strong poisons in isomerization catalysis. On the basis of both experimental data and theoretical calculations (DFT), a complete catalytic cycle for the isomerization of 2-propen-1-ol into propenal is described. The potential energy surfaces of the cycle have been explored at the B3LYP/6-311+G(d,p)//B3LYP/6-31G(d,p) + LAN2DZ level. The proposed mechanism involves the coordination of the oxygen atom of the allylic alcohol to the metal. The DFT energy profile is consistent with the experimental observation that the reaction only proceeds under heating. Calculations predict the catalytic cycle to be strongly exergonic, in full agreement with the high yields experimentally observed.

Syntheses, spectral and structural characterization of eta5- and eta6-cyclic pi-perimeter hydrocarbon platinum group metal complexes containing pyridazine-NHC analogues

A family of platinum group metal complexes containing bidentate pyridazine-NHC ligands (L1 = 3,6-bis(N-n-methylimidazolyl)pyridazine dichloride, L2 = 3,6-bis(N-n-butylimidazolyl)pyridazine dichloride) have been synthesized. The typical mechanism of the reactions for these syntheses involved an in situ carbene transfer reactions. Reaction of L1/L2 with silver oxide in absence of light yielded silver-NHC complexes (1) and (2). When, the respective metal precursors were added to the silver-NHC complexes, transmetallation occurred with the possible isolation of the following cationic complexes: [(eta6-C6H6)Ru(L)Cl]2+ {L = L1 (3), L2 (5)}, [(eta6-p-iPrC6H 4Me)Ru(L)Cl]2+ {L = L1 (4), L2 (6)}, [Cp *Rh(L)Cl]2+ {L = L1 (7), L2 (9)} and [Cp *Ir(L)Cl]2+ {L = L1 (8), L2 (10)}. All these complexes were stable in ambient atmosphere, and could be obtained in good yield. All these complexes were characterized by spectroscopic analyses. The molecular structure of the complex 9 was determined by single crystal X-ray diffraction studies.
