The rates for the photoinduced bimolecular reactions of a homologous series of Ru(II) diimines with cytochrome (cyt) c in its oxidized and reduced forms have been measured. The electronic coupling and reorganization energy of the system have been adjusted such that the inverted region may be accessed at reasonable driving forces. The electron transfer (ET) rate constants for *Ru(II) diimine/Fe(II)cyt c reaction increase monotonically and approach the diffusion limit of 8.8 x 108 M-1 s-1 at DeltaG = -0.7 V. At a higher driving force, which may be accessed with the powerfully oxidizing *Ru(diCF3-bpy)32+, the rate for ET is observed to drop off. Similarly, the high driving forces achieved with *Ru(II) diimine/Fe(III)cyt c (-DeltaG ? 1.12 V) are manifested in a decrease of the ET rate constant with increasing exergonicity. The observed ET rates for both systems are well described by a bimolecular model for ET occurring over an equilibrium distribution of reactant separation distances, each having a different formation probability and weighted by the first-order ET rate constant. The unique observation of bimolecular ET in the inverted region is not due to a peculiar reaction pathway engendered by the Ru(II) diimines, which react as do other small-molecule cations at the solvent-exposed edge of the heme. The inherent ET properties of cyt c engender a Marcus curve that is displaced below the diffusion limit and shifted to smaller driving forces.

Effective intervalence transfer occurred between the metal centers of ferrocene moieties that were adsorbed onto a ruthenium thin film surface by ruthenium-carbene pi bonds, a direct verification of Hush’s four-decade-old prediction. Electrochemical measurements showed two pairs of voltammetric peaks where the separation of the formal potentials suggested a Class II behavior. Additionally, the potential spacing increased with increasing ferrocene surface coverage, most probably as a consequence of the enhanced contribution from through-space electronic interactions between the metal centers. In contrast, the incorporation of a sp3 carbon spacer into the ferrocene-ruthenium linkage led to the diminishment of interfacial electronic communication.

Application of 10049-08-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 10049-08-8, Name is Ruthenium(III) chloride. In a document type is Article, introducing its new discovery.

The concept of nanocrystal conversion chemistry, which involves the use of pre-formed nanoparticles as templates for chemical transformation into derivative solids, has emerged as a powerful approach for designing the synthesis of complex nanocrystalline solids. The general strategy exploits established synthetic capabilities in simple nanocrystal systems and uses these nanocrystals as templates that help to define the composition, crystal structure, and morphology of product nanocrystals. This article highlights key examples of “conversion chemistry” approaches to the synthesis of nanocrystalline solids using a variety of techniques, including galvanic replacement, diffusion, oxidation, and ion exchange. The discussion is organized according to classes of solids, highlighting the diverse target systems that are accessible using similar chemical concepts: metals, oxides, chalcogenides, phosphides, alloys, intermetallic compounds, sulfides, and nitrides.

The chemical nature of the active ruthenium species and the mechanism of the oxidation of alcohols on Co-promoted Ru-hydroxyapatite have been investigated by in situ and ex situ EXAFS and kinetic analysis (reaction order of alcohol and oxygen, competing hydrogenation of primary and secondary alcohols, dehydrogenation in the absence of oxygen, kinetic isotope effect, Hammett study). It is concluded that the probable active sites are dihydroxo-ruthenium species (instead of RuCl2+ as suggested earlier) and only about half of them are accessible to the reactant benzyl alcohol. The oxidative dehydrogenation reaction obeys the Mars-van Krevelen mechanism and the reduced hydrido-ruthenium species is inactive in alcohol dehydrogenation without reoxidation by molecular oxygen. In the catalytic cycle, the rate limiting step is either the beta-hydride elimination step from the alcoholate or reoxidation of the ruthenium-hydride species, depending on the reaction conditions.

The electrochemical properties of both mononuclear L2RuIIPc and dinuclear [(THF)Rupc]2 species are described. The former is dominated by ring oxidation and reduction processes while the latter displays a series of metal localized processes. A Pourbaix diagram describes the various surfaces which can be generated by exposing a graphite electrode modified with [(THF)Rupc]2 to aqueous buffer at different polarization over a wide range of pH. The behavior of these various surfaces towards the electrocatalytic reduction of both oxygen and hydrogen peroxide is described. Most importantly, three different regimes of hydrogen peroxide reduction are observed dependent on the nature of the modified electrode surface. At high pH the four electron reduction of oxygen to water is observed via a 2 + 2 mechanism.

A process has been invented for the oxygenation of cyclic ethers. General problems in the process are the use of expensive and toxic oxidants, low TONs (turnover numbers), low selectivity and working at elevated temperatures (energy costs). These problems were solved by employing appropriate organometallic catalyst precursors. Using lnd(CO)3Mo-Ru(CO)2Cp, Cp(CO)3Mo-Ru(CO)2Cp and Cp(CO)2Ru-Ru(CO)2Cp or other ruthenium compounds, the aerobic oxidation of tetrahydrofurane (THF) proceeds at room temperature and produces selectively gamma-butyrolactone. Use of the catalysts yields replacement of stoichiometric, toxic co-oxidants by cheap air oxygen, working at room temperature, high selectivity, high TONs and overall formulation of green chemistry which is applicable to cyclic ethers: formula (I) The invented process satisfies the urge for green chemistry by using cheap air oxygen in a catalytic process with unlimited catalyst lifetime and plain water as the side product. Functionalised lactones will be available from corresponding ethers.
