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. 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

Gradient-corrected (BP86) and hybrid (M06-L) density functional calculations were used to study the relative stability of cis and /rans-dichloro X-chelated benzylldene ruthenium complexes (X = O, S, Se, N, P). Calculations In the gas phase differed from experimental results, predicting the /rans-dichloro configuration as being more stable In every case. The addition of Poisson-Boltzmann (PBF) continuum approximation (dlchloromethane) corrected the disagreement and afforded energies consistent with experimental results. Novel N, Se, and P chelated ruthenium olefin metathesis complexes were synthesized to evaluate calculation predictions. These findings reinforce the Importance of including solvent corrections In DFT calculations of ruthenium metathesis catalysts and predict that stronger sigma donors as chelating atoms tend to electronically promote the unusual and less active cis-dichloro configuration.

The first stereoselective total synthesis of the proposed structure of the gamma-lactone from Diaporthe sp. SXZ-19 was achieved by utilizing a convergent pathway. The four stereogenic centers were formed by employing Brown’s asymmetric alkoxyallylboration reaction, and a cross-metathesis reaction was used to construct the trans double bond of the gamma-lactone side chain. This synthesis led to a revision of proposed structural assignment of the natural product.

1-En-6-ynes react with alcohols or water in the presence of PtCl2 as catalyst to give carbocycles with alkoxy or hydroxy functional groups at the side chain. The reaction proceeds by anti attack of the alkene onto the (eta2-alkyne)platinum complex. The formation of the C – C and C – O bonds takes place stereoselectively by trans addition of the electrophile derived from the alkyne and the nucleophile to the double bond of the enyne. Formation of five- or six-membered carbo- or heterocycles could be obtained from 1-en-6-ynes depending on the substituents on the alkene or at the tether. Although more limited in scope, Ru(II) and Au(III) chlorides also give rise to alkoxy- or hydroxycyclization of enynes. On the basis of density functional theory (DFT) calculations, a cyclopropyl platinacarbene complex was found as the key intermediate in the process. In the presence of polar, nonnucleophilic solvents, 1-en-6-ynes are cycloisomerized with PtCl2 as catalyst. Formation of a platinacyclopentene intermediate is supported by DFT calculations. The reaction takes place by selective hydrogen abstraction of the trans-allylic substituent. Cycloisomerization of enynes containing disubstituted alkenes could be carried out using RuCl3 or Ru(AsPh3)4Cl2 in MeOH.

The in situ preparation of highly stereoretentive ruthenium-based metathesis catalysts is reported. This approach completely avoids the isolation of intermediates and air-sensitive catalysts, thus allowing for the rapid access and evaluation of numerous dithiolate Ru catalysts. A procedure was established to perform cross-metathesis reactions without the use of a glovebox, and on a small scale even Schlenk techniques are not required. Consequently, the chemistry displayed in this report is available to every practicing organic chemist and presents a powerful approach for the identification of new stereoretentive catalysts.

Synthetic Route of 10049-08-8, An article , which mentions 10049-08-8, molecular formula is Cl3Ru. The compound – Ruthenium(III) chloride played an important role in people’s production and life.

The conformational properties of a series of iron(II) and ruthenium(II) tris-bipyridine complexes have been investigated in a range of solvents. The complexes are equipped with pendant aromatic esters attached by flexible aliphatic linkers, and aromatic interactions between the edge of the bipyridine units and the face of the aromatic esters cause the complexes to fold up in solution. The extent of folding is assessed using 1H chemical shifts and found to be strongly solvent-dependent. Strong intramolecular edge-to-face aromatic interactions leading to stable folded structures are found in both polar solvents (water and alcohols) and nonpolar solvents (chlorinated hydrocarbons), but solvents of intermediate polarity such as DMSO destabilize the folded conformation. These results indicate that the aromatic interactions are dominated by a substantial electrostatic contribution in organic solvents but are sufficiently nonpolar to take advantage of solvophobic effects in polar solvents. This solvent dependence is likely to be a characteristic feature of any molecular recognition process which involves a mixture of both polar and nonpolar interactions.

Thiolate-coordinated ruthenium alkylidene complexes can give high Z-selectivity and stereoretentivity in olefin metathesis. To investigate their applicability as heterogeneous catalysts, we have successfully developed a methodology to easily immobilize prototype ruthenium alkylidenes onto hybrid mesostructured silica via a thiolate tether. In contrast, the preparation of the corresponding molecular complexes appeared very challenging in solution. These prototype supported complexes contain small thiolates but still, they are slightly more Z-selective than their molecular analogues. These results open the door to more active and selective heterogeneous catalysts by supporting more advanced thiolate Ru-complexes.
