Iodine oxidation of B3H8 – in glyme solution to produce (glyme)B3H7, followed by displacement of the coordinated glyme by reaction with anhydrous ammonia provides a safe and convenient preparation of ammonia triborane, NH3B3H7 (1). X-ray crystallographic determinations and DFT computational studies of both NH3B3H7 and the NH3B3H7-18-crown-6 adduct demonstrate that while computations predict a symmetric single bridging-hydrogen conformation, NH3B3H7 has a highly asymmetric structure in the solid-state that results from intermolecular N-H+ -H- -B dihydrogen bonding interactions. Studies of its hydrolytic reactions have shown that upon the addition of acid or an appropriate transition metal catalyst, aqueous solutions of 1 rapidly release hydrogen, with 6.1 materials wt % H2-release being achieved from a 22.7 wt % aqueous solution of 1 at room temperature in the presence of 5 wt % Rh/AI2O3 (1.1 mol% Rh). The rate of H2-release was controlled by both the catalyst loadings and temperature.

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.name: Ruthenium(III) chloride, you can also check out more blogs about10049-08-8

Pt-(RuOxHy)m electrocatalysts (m being the atomic Ru/Pt ratio) supported on multi-walled carbon nanotubes, in which amorphous hydrous ruthenium oxide (RuOxHy) is the exclusive Ru-containing species, were prepared and comprehensively characterized by X-ray diffraction, X-ray photoelectron spectroscopy, temperature-programmed reduction, thermogravimetric analysis and transmission electron microscopy techniques. Cyclic voltammetry (CV) and chronoamperometry studies of CO stripping and methanol electro-oxidation indicated that the CO tolerance and catalytic activity of Pt improved remarkably by the co-presence of RuO xHy. Repeated CV pretreatments in 0.5 M H 2SO4 up to potentials higher than 0.46 V (vs. SCE) induced significant dissolution of RuOxHy, which changed the RuOxHy content, Pt-RuOxHy proximity and surface structure of Pt, and consequently altered the electrocatalytic activity of Pt in the final electrode. However, RuOxHy dissolution was not identified when the pretreatment potentials was set no higher than 0.46 V. Discussion on the promotional function of RuO xHy was made based on the peculiarity of RuO xHy as a mixed electron/proton conductor.

The complexes TpRu[P(OCH2)2(OCCH3] (PPh3)Cl (2) [Tp = hydridotris(pyrazolyl)borate; P(OCH 2)2(OCCH3) (1) = (4-methyl-2,6,7-trioxa-1- phosphabicyclo[2,2,1]heptane] and TpRu(L)(PPh3)Cl [L = P(OCH 2)3CEt (3), PMe3 (4) or P(OMe)3 (5)], (eta6-C6H6)Ru(L)Cl2 [L = PPh3 (6), P(OMe)3 (7), PMe3 (8), P(OCH 2)3CEt (9), CO (10) or P(OCH2) 2(OCCH3) (11)] and (eta6-p-cymene)Ru(L) Cl2 [L = P(OCH2)3CEt (12), P(OCH 2)2(OCCH3)P(OCH2) 2(OCCH3) (13), P(OMe)3 (14) or PPh3 (15)] have been synthesized, isolated, and characterized by NMR spectroscopy, cyclic voltammetry, mass spectrometry, and, for some complexes, single crystal X-ray diffraction. Data from cyclic voltammetry and solid-state structures have been used to compare the properties of (1) with other phosphorus-based ligands as well as carbon monoxide. Data from the solid-state structures of Ru(II) complexes show that P(OCH2)2(OCCH3) has a cone angle of 104. Cyclic voltammetry data reveal that the Ru(II) complexes bearing P(OCH2)2(OCCH3) have more positive Ru(III/II) redox potentials than analogous complexes with the other phosphorus ligands; however, the Ru(III/II) potential for (eta6-C 6H6)Ru[P(OCH2)2(OCCH 3)]Cl2 is more negative compared to the Ru(III/II) potential for the CO complex (eta6-C6H 6)Ru(CO)Cl2. For the Ru(II) complexes studied herein, these data are consistent with the overall donor ability of 1 being less than other common phosphines (e.g., PMe3 or PPh3) or phosphites [e.g., P(OCH2)3CEt or P(OMe)3] but greater than carbon monoxide.

The reaction of various pyridine-2-carboxaldimine ligands with the [(eta6-arene)Ru(mu-Cl)Cl]2 dimer followed by a metathesis reaction with ammonium hexaflourophosphate, yielded the ruthenium(II) arene complex salts [(eta6-arene)RuCl(C5H4[Formula presented]6; where (arene = C6H6 (1), p-cymene (2), Ar = 3, 5-dimethyl phenyl (a), 2,3-dimethyl phenyl (b), 2,5-dimethyl phenyl (c), 3,4-dimethyl phenyl (d)). The compounds were characterized by elemental analysis, FT- IR, UV?vis and 1H and 13C NMR. Single crystal X-ray structures for compounds 1a, 1d and 2e were also determined and showed that the ruthenium(II) centre has a pseudo-octahedral geometry and the molecule adopted a three legged piano stool geometry in which the arene ring occupies the apex and the nitrogen atoms of the N,N?-bidentate ligand and the chloride atom the base of the stool. The Ru(II) complex salts were active for the catalytic transfer hydrogenation of ketones into alcohols in the presence of NaOH using 2-propanol as the hydrogen source at 82 C. The complexes were suitable for a wide range of aliphatic, cyclic and aromatic ketones giving good turn over numbers.

This paper describes effective photocurrent generation based on a polymer Langmuir-Blodgett (LB) monolayer containing ruthenium complex on a silver electrode excited by surface plasmon resonance (SPR). It was found that photocurrent generation is greatly enhanced at an incident angle where the electromagnetic field was most enhanced by SPR. At this angle, the photocurrent is enhanced by a factor of 23.6 compared with that at the critical angle for total internal reflection. The incident monochromatic photon-to-current conversion efficiency was 9.53*10-3 percent, higher than that of the corresponding polymer LB monolayer film on a transparent indium tin oxide electrode with conventional direct transmitted light (2.87*10-3 percent). Furthermore, it was demonstrated that precoating with poly(N-decylacrylamide) homopolymer ensures adequate separation of the Ru (bpy)3(2+) and silver surface, thereby suppressing the quenching of photoexcited Ru(bpy)3(2+) by the silver. Controlling the distance between the Ru(bpy)3(2+) layer and the silver using the Langmuir-Blodgett technique leads to effective photoexcitation of Ru(bpy)3(2+) by SPR and suppression of quenching by the silver surface, resulting in efficient photocurrent generation.

The dimeric palladium(I) complex [Pd(mu-Br)tBu 3P]2 was found to possess unique activity for the catalytic double-bond migration within unsaturated compounds. This isomerization catalyst is fully compatible with state-of-the-art olefin metathesis catalysts. In the presence of bifunctional catalyst systems consisting of [Pd(mu-Br)tBu3P]2 and NHC-indylidene ruthenium complexes, unsaturated compounds are continuously converted into equilibrium mixtures of double-bond isomers, which concurrently undergo catalytic olefin metathesis. Using such highly active catalyst systems, the isomerizing olefin metathesis becomes an efficient way to access defined distributions of unsaturated compounds from olefinic substrates. Computational models were designed to predict the outcome of such reactions. The synthetic utility of isomerizing metatheses is demonstrated by various new applications. Thus, the isomerizing self-metathesis of oleic and other fatty acids and esters provides olefins along with unsaturated mono- and dicarboxylates in distributions with adjustable widths. The cross-metathesis of two olefins with different chain lengths leads to regular distributions with a mean chain length that depends on the chain length of both starting materials and their ratio. The cross-metathesis of oleic acid with ethylene serves to access olefin blends with mean chain lengths below 18 carbons, while its analogous reaction with hex-3-enedioic acid gives unsaturated dicarboxylic acids with adjustable mean chain lengths as major products. Overall, the concept of isomerizing metatheses promises to open up new synthetic opportunities for the incorporation of oleochemicals as renewable feedstocks into the chemical value chain.
