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.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.203714-71-0, Name is Dichloro(2-isopropoxyphenylmethylene)(tricyclohexylphosphine)ruthenium (II), molecular formula is C28H45Cl2OPRu.

Two isotopically and structurally labeled Ru-based carbenes (2-d 4 and 13) have been prepared and attached to the surface of monolithic sol-gel glass. The resulting glass-supported complexes (18-d n and 19) exhibit significant catalytic activity in promoting olefin metathesis reactions and provide products of high purity. Through analysis of the derivatized glass pellets used in a sequence of catalytic ring-closing metathesis reactions mediated by various supported Ru carbenes, it is demonstrated that free Ru carbene intermediates in solution can be scavenged by support-bound styrene ether ligands prior to the onset of competing transition metal decomposition. The observations detailed herein provide rigorous evidence that the initially proposed release/return mechanism is, at least partially, operative. The present investigations shed light on a critical aspect of the mechanism of an important class of Ru-based metathesis complexes (those bearing a bidentate styrene ether ligand).

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.Computed Properties of C28H45Cl2OPRu, you can also check out more blogs about203714-71-0

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.

Novel regioselective ring closing ene-yne metathesis provided an efficient access to different substituted 1-benzazepine scaffolds. The reported synthetic approach could also be used as a powerful tool for the selective formation of a highly functionalizable 2-benzazepine core. This synthetic protocol was even proved to be an efficient way to obtain a functionalizable benzazocine derivative. By modifying the structure of the starting materials, the optimized cyclization finally proved to be a suitable technique to obtain five- and six-membered lactams, enhancing the synthetic application of our method. Five- and six-membered lactams were efficiently prepared by ring-closing metathesis involving the loss of ethylene moiety and affording highly functionalizable compounds showing both electron-withdrawing substituents and electron-donor groups.

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.

Diastereomerically pure complexes of formula CpRuCl(PP*) and CpRuH(PP*) with chiral ferrocenyl diphosphines were prepared and the selectivity of proton-transfer processes over the monohydride compounds with different acids was studied. With 1 equiv of HBF4 the cis-dihydrogen and trans-dihydride complexes were formed while with 3 equiv of CF 3CO2H the trans-dihydride derivative was the only product. However, the use of 1 equiv of CF3CO2H led to a dihydrogen bonded complex with an extremely short RuH…HO 2CF3 interaction that exhibits proton-hydride exchange. Using the labeled acid CF3CO2D, a stereoselective transference of the deuteron was demonstrated that implies the previous epimerization of the monohydride and the subsequent attack of the acid in the position previously occupied by the hydride.

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.

Treatment of the hydrido(dihydrogen) compound [RuHCl(H2) (PCy3)2] 1 with alkynes RC?CH (R = H, Ph) afforded the hydrido(vinylidene) complexes [RuHCl(=C=CHR)(PCy3)2] 2, 3 which react with HCl or [HPCy3]Cl to give the corresponding Grubbs-type ruthenium carbenes [RuCl2(=CHCH2R)(PCy 3)2] 4, 5. The reaction of 2 (R = H) with DCl, or D 2O in the presence of chloride sources, led to the formation of [RuCl2(=CHCH2D)(PCy3)2] 4-d 1. Based on these observations, a one-pot synthesis of compounds 4 and 5 was developed using RuCl3·3H2O as the starting material. The hydrido(vinylidene) derivative 2 reacted with CF 3CO2H and HCN at low temperatures to yield the carbene complexes [RuCl(X)(=CHCH3)(PCy3)2] 6,7, of which 7 (X = CN) was characterized crystallographically.

[Figure not available: see fulltext.] Double bond isomerization by in situ generated ruthenium hydride catalyst in 6- to 9-membered hydrazine heterocycles including an endocyclic N?N bond was investigated. Based on the results of the experiments, a conclusion was made that the generation of resonance-stabilized enehydrazides is generally favored, but in some cases, the reaction pathway is presumably also highly dependent of steric interactions. With the current method, two novel enehydrazide heterocycles and one enehydrazine heterocycle were produced and characterized.
