Atom transfer radical additions with the cationic half-sandwich complex [Cp*Ru(PPh3)2(CH3CN)]OTf

The cationic ruthenium half-sandwich complex [Cp*Ru(PPh 3)2(CH3CN)][OTf] (2) (Cp* = eta5-C5Me5, OTf = SO3CF 3) was synthesized by reduction of [Cp*RuCl2] 2 with zinc in the presence of NaOTf and subsequent reaction with PPh3. When NaOTf was omitted, the corresponding tetrachlorozincate salts were obtained. Complex 2, as well as the salts [Cp*Ru(CH 3CN)3]2[ZnCl4] (3) and [Cp*Ru(PPh3)2-(CH3CN)] 2[ZnCl4] (4), were characterized by single-crystal X-ray analysis. Complex 2 proved to be a potent catalyst for the atom transfer radical addition of CCl4 and CHCl3 to terminal olefins, displaying a performance superior to that of the previously described neutral catalyst [Cp*RuCl(PPh3)2]. For the addition of CHCl3 to styrene, a total turnover number of 890 was achieved. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.

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.HPLC of Formula: C46H45ClP2Ru, you can also check out more blogs about92361-49-4

Prediction of ring formation efficiency via diene ring closing metathesis (RCM) reactions using the M06 density functional

Using density functional theory employing the M06 functional, we predict the reaction path energetics of ring formation via diene ring closing metathesis (RCM) reactions, and thence the effective molarity (EM) for the formation of cyclohexene, which is in good accord with the experimental lower limit which we report here.

Flash microwave synthesis and sintering of nanosized La0.75Sr0.25Cr0.93Ru0.07o3-delta for fuel cell application

Perovskite-oxide nanocrystals of La0.75Sr0.25Cr0.93Ru0.07O3-delta with a mean size around 10 nm were prepared by microwave flash synthesis. This reaction was performed in alcoholic solution using metallic salts, sodium ethoxide and microwave autoclave. The obtained powder was characterised after purification by energy dispersive X-ray analysis (EDX), X-ray powder diffraction (XRD), BET adsorption technique, photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM). The results show that integrated perovskite-type phase and uniform particle size were obtained in the microwave treated samples. At last the synthesised powder was directly used in a sintering process. A porous solid, in accordance with the expected applications, was then obtained at low sintering temperature (1000 C) without use of pore forming agent.

Extending metal-capped polyynediyl molecular wires by insertion of inorganic metal units

Several symmetric and asymmetric bis(metalla-diynediyl)ruthenium(II) complexes of the general formula trans-{LxRu} C?CC?C{Ru(dppe)2}C?CC?C{RuL? y} (Lx, L?y = (PPh3) 2Cp, (dppe)Cp, (dppe)Cp*), containing Ru(dppe)2 as the central linking group, have been successfully synthesized and characterized spectroscopically. DFT calculations show that their HOMO’s are delocalized over the Ru-C4-Ru-C4-Ru chain, suggesting that there is electronic interaction between the terminal RuLx groups through the C4 chains and the Ru(dppe)2 center. Limited electrochemical measurements reveal that the complexes undergo a series of five stepwise reversible or quasi-reversible oxidation processes.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 32993-05-8 is helpful to your research., Electric Literature of 32993-05-8

Hydrogenation of beta-N-substituted enaminoesters in the presence of ruthenium catalysts

beta-Aminoesters were prepared in two simple steps from beta-ketoesters derivatives and primary amines under mild conditions. Their hydrogenation was performed at 50 C in the presence of several organometallic catalysts under acidic conditions. The new beta-N-substituted aminoesters were isolated in moderate to good yields.

Aza-Claisen rearrangement in the cyclization reactions of nitrogen-containing enynes via ruthenium vinylidene complexes

The cyclization reaction of several diallyl aromatic amine molecules, each containing an ethynyl group at the ortho position of the aromatic ring, is accompanied by an aza-Claisen rearrangement, causing an allyl group migration to give substituted indole compounds. This cyclization is catalyzed by ruthenium triphenylphosphine and diphenylphosphinoethane (dppe) complexes as well as gold complexes with silver reagent. The less sterically crowded dppe complex is a more efficient catalyst. The mechanism involving a vinylidene intermediate is proposed on the basis of isolation of several intermediates in the ruthenium-catalyzed system. Single crystals of a metal complex with the cyclized ligand were obtained, and the structure was determined by an X-ray diffraction analysis.
