A series of nine cyclopentadienyl Ru(ii)-NHC complexes (1-9) have been synthesised by systematically varying the ligand and/or ligand substituents: eta5-C5H4R? (R? = H, Me), EPh3 (E = P, As), NHC (Im, BIm), where NHC = Im(R)(R?) (R, R? = Me, Bn, 4-NO2Bn, C2H4Ph, C4H7). Each of the Ru(ii)-NHC complexes features an N-alkenyl tether to attain bidentate NHC ligands. All complexes found application as catalysts in the tandem transfer hydrogenation and epoxidation reactions of carbonyl substrates. The catalytic activity of the complexes was shown to be similar, with efficiencies of up to 69% conversion after 18 hours and varying alcohol:epoxide selectivity for a variety of electronically diverse carbonyl substrates. Complex 3, with a nitro-containing substituent on the NHC ligand, was the only complex that showed preference for the alcohol product over the epoxide after 18 hours of reaction time.

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., Reference of 32993-05-8

Me3SiCCC4H2S-5-NO2 was synthesized in good yield by palladium-catalyzed cross-coupling of ethynyltrimethylsilane and 2-bromo-5-nitrothiophene or 2-iodo-5-nitrothiophene. Reactions of Me3SiCC(C4H2S)NO2 with a series of ruthenium chloride complexes [RuClLL?(Cp?)] gave the alkynyls [Ru(2-CCC4H2S-5-NO2) LL?(Cp?)] (L, L?=CO, PMe2Ph or PPh3; Cp?=C5H5 or C5Me5). These metal complexes, each with a strongly electron-donating metal center at one end and an electron-accepting organic substituent at the other end of a pi-conjugated chain, are strongly polarized and are expected to demonstrate non-linear optical activity.

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.Recommanded Product: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8

The syntheses of seven macrocyclic analogues of the neuroprotective tripeptide glycyl-l-prolyl-l-glutamic acid (GPE) 1 are described. Macrocycles 6 and 7 mimic the cis conformer of GPE whereas macrocycles 2-5, 8, and 9 mimic the trans conformer of GPE. The macrocyclic peptides of well-defined geometry were prepared via Grubbs ring closing metathesis of an appropriate diene precursor. In turn each of the diene precursors were prepared from the readily available allyl-substituted amino acid building blocks 12, 13, 14, 27, 36 and 51. The Royal Society of Chemistry 2006.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 20759-14-2, Name is Ruthenium(III) chloride hydrate, molecular formula is Cl3H2ORu.

The catalytic activities of several alumina-supported monometallic sulfides covering a wide range of heats of formation or metal-sulfur bond energies, namely, Mn, Fe, Zn, Cu, Ni, Ru, Mo, and Re sulfides, have been measured for the hydrogenation of cyclohexene, the hydrodesulfurization (HDS) of benzothiophene, and the hydrodesulfurization of dibenzothiophene under typical hydrotreating conditions. For the hydrodesulfurization of dibenzothiophene a volcano curve similar to the one reported for bulk sulfides (Pecoraro, T., and Chianelli, R. R., J. Catal. 67, 430 (1981)) is found when the HDS activities are plotted versus the metal-sulfur bond energy, suggesting that the alumina support has no major infuence on the volcano curve. For cyclohexene hydrogenation and benzothiophene HDS different trends are found, suggesting that the activity trends depend on the nature of the reactant and/or reaction. The activities expressed in moles of reactant per mole of sulfided metal of Mn, Fe, Zn, Cu, and Ni sulfides are found to be very low, whereas the activities of Ru, Mo, and Re sulfides are high and of the same order of magnitude.

In recent years, olefin cross metathesis (CM) has emerged as a powerful and convenient synthetic technique in organic chemistry; however, as a general synthetic method, CM has been limited by the lack of predictability in product selectivity and stereoselectivity. Investigations into olefin cross metathesis with several classes of olefins, including substituted and functionalized styrenes, secondary allylic alcohols, tertiary allylic alcohols, and olefins with alpha-quaternary centers, have led to a general model useful for the prediction of product selectivity and stereoselectivity in cross metathesis. As a general ranking of olefin reactivity in CM, olefins can be categorized by their relative abilities to undergo homodimerization via cross metathesis and the susceptibility of their homodimers toward secondary metathesis reactions. When an olefin of high reactivity is reacted with an olefin of lower reactivity (sterically bulky, electron-deficient, etc.), selective cross metathesis can be achieved using feedstock stoichiometries as low as 1:1. By employing a metathesis catalyst with the appropriate activity, selective cross metathesis reactions can be achieved with a wide variety of electron-rich, electron-deficient, and sterically bulky olefins. Application of this model has allowed for the prediction and development of selective cross metathesis reactions, culminating in unprecedented three-component intermolecular cross metathesis reactions.

A pyrene-tagged ruthenium carbene 8 was synthesized and immobilized on single-walled carbon nanotubes (SWNTs) via pi-pi stacking. These pi-pi interactions were greatly affected by the reaction temperature and the solvent polarity, thus, offering a new reversible immobilization model that can be controlled by reaction temperature in polar solvents, such as acetone. SWNTs-supported ruthenium carbene 8 is a robust and recyclable catalyst system. Six to seven cycles were achieved for ring-closing metathesis of selected substrates. Importantly, after the complete loss of activity, the SWNTs can be easily recycled by washing with tetrahydrofuran. The recycled SWNTs can then be reloaded with 8. The reusability of the catalyst supported on recycled SWNTs is comparable with that supported on fresh SWNTs.

Ruthenafuran and osmafuran monocationic complexes [Ru([14]aneS4)(C?O)]+ or [M(bpy)2(C?O)]+ (C?O = anionic bidentate chelate [C(OR)CHC(Ph)-O]-; [14]aneS4 = 1,4,8,11-tetrathiacyclotetradecane; M = Ru, Os; bpy = 2,2?-bipyridine) have been prepared from reactions between phenyl-ynone HC-C(CO)Ph and [Ru([14]aneS4)Cl2] or [M(bpy)2Cl2] in alcoholic solvents ROH. The formation of metal-vinylidene intermediate, followed by nucleophilic attack by RO-, and carbonyl group coordination to the metal center are believed to be the key steps in the formation of these metallafurans. The nature of the anionic C?O ligand was investigated by electrochemical, spectroscopic, and theoretical means.
