Synthesis of chiral diphosphine ligands containing a spiro scaffold was described. The ruthenium complexes of these spiro ligands were found to have extremely high activities (S/C up to 100000) and enantioselectivities (ee up to 99.5%) in the asymmetric hydrogenation of aromatic, heteroaromatic, and alpha,beta-unsaturated ketones.

A document type is Article, introducing its new discovery.

A comprehensive photophysical study has been carried out on the two complexes [(bpy)2Ru(4,4?-PE-bpy)]2+ and [(bpy)2Ru(5,5?-PE-bpy)]2+ (44Ru and 55Ru, respectively, where bpy = 2,2?-bipyridine and PE = phenyleneethynylene). The objective of this work is to determine the effect of the phenyleneethynylene substituents on the properties of the metal-to-ligand charge-transfer excited state. The complexes have been characterized by using UV-visible absorption, photoluminescence, and UV-visible and infrared transient absorption spectroscopy. The results indicate that the MLCT excited state is localized on the PE-substimted bpy ligands. Moreover, the photophysical data indicate that in the MLCT excited state the excited electron is delocalized into the PE substituents and the manifestations of the electronic delocalization are larger when the substituents are in the 4,4?-positions.

(Chemical Equation Presented) A strategy for the asymmetric synthesis of chiral-at-metal [Ru(pp)(pp?)(pp?)]2+ complexes, where pp, pp?, and pp? are achiral 2,2?-bipyridines, is introduced. The method employs isopropyl-2-(2?-hydroxyphenyl)oxazolines as chiral auxiliaries, which serve in their deprotonated forms as strong bidentate ligands that provide excellent asymmetric induction in the course of the coordination chemistry and, importantly, can afterward become substituted with complete retention of configuration in the presence of acid.

Strained ruthenium (Ru) complexes have been synthesized and characterized as novel agents for photodynamic therapy (PDT). The complexes are inert until triggered by visible light, which induces ligand loss and covalent modification of DNA. An increase in cytotoxicity of 2 orders of magnitude is observed with light activation in cancer cells, and the compounds display potencies superior to cisplatin against 3D tumor spheroids. The use of intramolecular strain may be applied as a general paradigm to develop light-activated ruthenium complexes for PDT applications.

Designing the effective metallodrugs with amphiphilic nature is an active approach for the biomedical applications such as chemotheraphy, bioimaging, drug carrier, etc. To elaborate this, some fluorescent emissive surfactant?ruthenium(II) complexes and its precursor ruthenium(II) complexes have been interacted with calf thymus DNA (CT?DNA) for understanding the biophysical impacts of head and tail parts of the metallosurfactants. Here, DNA binding studies were examined by UV?visible absorption, fluorescence, circular dichroism and viscosity measurements. The obtained results showed that surfactant?ruthenium(II) complexes effectively bind with CT?DNA through hydrophobic interactions dominated moderate intercalation, whereas precursor ruthenium(II) complexes interact CT?DNA through electrostatic interactions dominated moderate intercalation. Also, increase of hydrophobic alkyl amine chain length as well as size of the head group in surfactant?ruthenium(II) complexes increased the binding affinity with CT?DNA, in which tail group played a dominant role. Further investigations of antibacterial, hemolytic and anticancer activities showed that desired biological activities could be obtained by tuning the head and tail groups of the metallodrugs in near future.

A facile procedure for the incorporation of Ru(bpy)32+ in an oligonucleotide is reported. A Ru(bpy)32+ phosphoramidite is synthesized, and then attached to the 5′-terminus of DNA using a standard protocol on an automated DNA solid-phase synthesizer. Photophysical studies of the Ru(II) tris-diimine complex as well as the corresponding labeled oligonucleotides demonstrate that the excited-state electron is localized on one specific bipyridine with the dipole directed toward the linkage to DNA, and that the Ru(II) excited state is long-lived when attached to the DNA.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Safety of Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.

Thechiral P-N* ligands [(S)-2-(dimethyIamino)-3-phenylpropyl]diphenylphosphine, (S)-phephos, 1, [(5)-2-(dimethylamino)-2-phenyIethyl]diphenylphosphine, (S)-phglyphos, 2, [(S)-2-(dimethylamino)-3-methylbutyl]-diphenylphosphine, (SJ-valphos, 3, and [(+)-(2S, 3/J)-4-(dimethylamino)-3-methyl]-2-diphenylphosphinoxy-l, 2-diphenylbutane, (+)-(25, 3)-chiraldphos, 4, reacted with [Ru(n6-arene)Cl2]2 (arene =/?-cymene, benzene or hexamethylbenzene), in dichloromethane or tetrahydrofuran solution, affording the corresponding [Ru(eta6-arene)-(P-N*)C12] complexes, 5, in which the P-N* acts as a monodentate P-bonded ligand. In methanol the same reactions easily afforded the corresponding chelate complexes [Ru(eta6-arene)(P-N*)Cl]Cl. Using ligands 1-3, when the arene is/j-cymene, 90:10 diastereomeric mixtures of the cationic complexes have been obtained while only one diastereomer was formed in the corresponding reactions when the arene is benzene or hexamethylbenzene. The determination of the absolute configuration of the major products as RRa, Sc diastereoisomers was made from the crystal structure and CD spectra comparison of the complex (Ru, Sc)-[Ru(n6-/7-MeC6H4Pr’)-(5-phglyphos)Cl]BF4. Complexes [Ru(n6-arene)(P-N*)Cl]Cl were also obtained by adding small amounts of methanol to solutions of [Ru(eta6-arene)(P-N*)Cl2] in chloroform. A kinetic study, in CDC13 solution containing variable amounts of methanol, on the chelation process in the neutral species [Ru(n6-arene)(P-N*)ClJ showed first-order behaviour of the A’obs values with the nucleophile (methanol) concentration. The pseudo-first-order rate constants are ascribed to replacement of Cl- by a molecule of methanol. A reaction mechanism is proposed. The Royal Society of Chemistry 2000.

The photochromic behavior of several spirooxazines (SO) containing phenanthrene or phenanthroline moieties in the oxazine part of molecules has been investigated in several solvents and phosphatidylcholine (PC) liposomes. The solvatochromic properties of the merocyanine (MC) forms of these dyes were used to probe their location within the PC membrane. Transient spectroscopic measurements revealed that, when first formed by photoexcitation, the MC forms of phenanthroline-containing spirooxazines were located at relatively nonpolar sites within the membrane, but they subsequently moved to a more polar environment typical of the aqueous- organic interface. The characteristic time for this intersite movement was tau ? 10-3 s, corresponding to a diffusion coefficient of D ? 10-11 cm2 s-1. In contrast, these spectral shifts were not observed when PC liposome- bound SO containing the phenanthrene moiety were photoexcited, suggesting that either intersite diffusion was more rapid for these compounds or the initially formed MC (and its spiro precursor) were located in a more polar microenvironment. The rate of thermal ring-closing following UV photoexcitation decreased modestly when either an electron-withdrawing group was present on the MC oxazine ring or an electron-donating group was present on the MC indoline ring. A dramatic increase in the ring-closing rate was observed for an o-phenanthroline-containing SO coordinated to a Ru(bpy)22+ metal center, an effect attributable to strong donation of electron density from the Ru(II) d-orbitals into the ligand pi*-orbitals.
