The transmetallation reaction between [(eta6-arene)RuCl2]2 (eta6-arene = C6H6 (benzene) (1); 1-Me-iPr-C6H4 (cymene) (2); 1,2,4,5-Me4-C6H2 (durene) (3); 1,2,3,5-Me4-C6H2 (isodurene) (4)) and the aminoaryl-mercury derivatives Hg{Q-dmba}2 (Q-dmba = 1-{C6H3-3-F-6-CH2NMe2} (a); 1-{C6H3-3-Me-6-CH2NMe2} (b); 1-{C6H2-2,3-OCH2O-6-CH2NMe 2} (c); 1-{C6H2-2,4-(MeO)2-6-CH2NMe 2} (d); 1-{C6H4CH2NMe2} (e)) affords the corresponding C,N-cycloruthenated complexes [(eta6-arene)RuCl{Q-dmba}]. All complexes were characterised by 1H and 13C{1H} NMR. The reaction seems to be governed by steric rather than by electronic factors: an increase in the number of alkyl substituents in the eta6-arene ligand or the presence of bulky groups ortho to Hg in the starting material leads to a significant decrease of the yields of the desired cycloruthenated products.

New phenoxybenzylidene ruthenium chelates were synthesised from the second generation Grubbs catalysts bearing a triphenylphosphine ligand (or its para-substituted analogues) by metathesis exchange with substituted 2-vinylphenols. The complexes behave like a latent catalyst and are characterized by an improved catalytic behaviour as compared to that of the known analogues, i.e., they exhibit high catalytic inactivity in their dormant forms and a profound increase in activity after activation with HCl. The strong electronic influence of substituents in the chelating ligand on the catalytic activity was demonstrated. The catalytic properties were tested in ROMP of cyclooctadien (COD) and a single selected norbornene derivative.

Cyclic voltammograms in acetonitrile of 1a, 2a, and 3a display one-electron oxidations at 0.72, 0.71, 0.63 V, respectively, consistent with a Ru(III/II) couple. Compounds 1b, 2b, and 3b show a pH independent couple at pH<2 and a pH dependent couple consistent with a one-electron, one-proton process at pH values from ca. 2 to 11. Past pH 11 this redox process becomes pH independent again, and the compounds become unstable. The one-electron nature was verified by bulk electrolysis and spectroelectrochemical measurements.

Related Products 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 kinetics of Os(VIII) and Ru(III) catalysed oxidation of anti-pyretic drug, aspirin by diperiodatoargentate(III) (DPA) in alkaline medium at 298 K and a constant ionic strength of 0.10 mol dm-3 was studied spectrophotometrically. The oxidation products in both the cases are 1,4-benzoquinone2-carboxylate ion and Ag(I). The stoichiometry is the same in both the catalysed reactions i.e., [aspirin]:[DPA] = 1:2. The reaction is of first order in Os(VIII)/Ru(III) and [DPA] and has less than unit order in both [ASP] and [alkali]. The oxidation reaction in alkaline medium has been shown to proceed via a Os(VIII)/Ru(III)-aspirin complex, which further reacts with one molecule of DPA in a rate determining step followed by other fast steps to give the products. The main products were identified by spot test, IR, NMR and GC-MS. The reaction constants involved in the different steps of the mechanism are calculated. The catalytic constant (Kc) was also calculated for both catalysed reactions at different temperatures. From the plots of log K c versus 1/T, values of activation parameters with respect to the catalyst have been evaluated. The activation parameters with respect to slow step of the mechanism are computed and discussed and thermodynamic quantities are also determined. It has been observed that the catalytic efficiency for the present reaction is in the order of Os(VIII) > Ru(III). The probable active species of catalyst and oxidant have been identified.
