Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 172222-30-9, Name is Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, Formula: C43H72Cl2P2Ru.

A study concerning the effects of chelation on the structure and catalytic activity of ruthenium carbene complexes was presented. The ruthenium chelate complexes were prepared by reaction of the Grubbs catalyst and its second-generation analogue with the 2-vinylbenzoic acid isopropyl ester in the presence of CuCl. The fact that the chelating carbonyl group in these complexes attenuates their catalytic activity sets an experimental basis for the interpretation of reactivity data.

Phenazinic ligands and Ru(ii)-based complexes were synthesized from natural products lapachol and lawsone and evaluated against T. cruzi, the etiological agent of Chagas disease. These new ruthenium compounds could provide promising trypanocidal drugs. Besides synthesis and trypanocidal activity, this paper reports photophysical features and computational details of the compounds. The fluorescent trypanocidal substances are promising derivatives for further studies aiming to find molecules active against parasites associated with neglected diseases.

A new series of ruthenium polypyridyl complexes with a hydroxypyridine ligand were prepared, and their properties were investigated spectroscopically and electrochemically. Particular focus is paid to the effects of protonation-deprotonation and ethylation of the hydroxypyridine ligand, which affects the NMR, electronic spectroscopy, and electrochemistry of the complex. The changes to the UV-vis spectrum were used to determine a pka of 10.5 for the hydroxypyridine nitrogen. In the NMR, protonation of the hydroxypyridine ligand of the complex causes changes in the chemical shifts of the protons on both the hydroxypyridine and bipyridine rings, indicating some degree of electronic communication between these ligands. In addition, it is found that deprotonation of the hydroxypyridine ligand strongly affects the redox potential of the ruthenium metal center, shifting it more negative by 0.4 V. While the electrochemistry of the protonated complex contains irreversible electrochemical events, both deprotonation and subsequent ethylation of the hydroxypyridine ligand result in reversible electrochemistry for all events within the solvent window. For the ethylated complex, we search for a ligand to ligand charge transfer band, corresponding to electron transfer between bipyridine ligands in the mixed valence state. Despite the potential for electronic coupling between ligands through the metal center, we were unable to find any spectroscopic evidence of such electronic coupling.

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: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), you can also check out more blogs about15746-57-3

It has been observed that the perruthenate formed on addition of ruthenium trichloride to peroxodisulphate solution in base decomposes, with loss of oxygen, to form ruthenate.Contrary to thermodynamic prediction, the latter species appears to be highly stable in the presence of excess of peroxodisulphate providing reactive organic species such as alcohols are not present.Addition of alcohols to the ruthenate-peroxodisulphate mixture at high pH affords a perruthenate-alcohol complex, the latter acting as an effective catalyst for the homogeneous oxidation of primary or secondary alcohols by the peroxodisulphate.A mechanism based on alpha-hydride abstraction has been proposed for the latter reaction, and the simultaneous formation of the insoluble dioxide RuO2*H2O attributed to further reaction of the two products, ruthenate and aldehyde.Although there have been several claims to the contrary, ruthenate (RuO42-) species do not directly oxidize alcohols (other than methanol); they are, however, capable of readily oxidizing aldehydes.

The catalytic networks of methylotrophic organisms, featuring redox enzymes for the activation of one-carbon moieties, can serve as great inspiration in the development of novel homogeneously catalyzed pathways for the interconversion of C1molecules at ambient conditions. An imidazolium-tagged arene?ruthenium complex was identified as an effective functional mimic of the bacterial formaldehyde dismutase, which provides a new and highly selective route for the conversion of formaldehyde to methanol in absence of any external reducing agents. Moreover, secondary amines are reductively methylated by the organometallic dismutase mimic in a redox self-sufficient manner with formaldehyde acting both as carbon source and reducing agent.

Novel sulfoxide-ligated ruthenium complexes were prepared by reacting second-generation metathesis precatalysts with p-toluenesulfonyl chloride in the presence of a small excess of sulfoxide. (SIMes)Ru(S-DMSO)(Ind)Cl2 (M54) and (SIMes)Ru(S-DMSO)(CHPh)Cl2 (M54a) were characterized crystallographically and, in agreement with NMR spectroscopy, were found to adopt an unusual cis-dichloro configuration. Despite having traditionally latent geometry, the new complexes were found to be highly reactive precatalysts for routine metathesis transformations. Additionally, the robustness, scalability, and industrial utility of M54 as a ruthenium synthon are demonstrated.

We have developed a new strategy that uses the Kroehnke synthesis for the preparation of various substituted phenylpyridines in excellent yields (up to 88%). Starting with the appropriate commercially available acetophenone, a variety of phenylpyridines substituted by either electron-donating (i.e. methyl, methoxy) or -withdrawing groups (i.e. bromide, nitro) on the phenyl ring are obtained in a two-step synthesis. The corresponding functionalized cyclometalated ruthenium complexes can be prepared with unusually high yields by using methanol as reaction solvent. The electrochemical data of the complexes demonstrate the strong sigma-donating character of the anionic phenylpyridine ligand. X-ray analyses of four complexes show a shortening of the Ru-C bond associated with the elongation of only one of the five Ru-N bonds (trans effect). Wiley-VCH Verlag GmbH & Co, KGaA, 2006.
