Reference of 301224-40-8, An article , which mentions 301224-40-8, molecular formula is C31H38Cl2N2ORu. The compound – (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride played an important role in people’s production and life.

A new methodology for the synthesis of enantiomerically enriched bicyclic delta-sultams is described, involving an initial organocatalytic intramolecular aza-Michael reaction of vinyl sulfonamides bearing a conjugated ketone at a remote position. The resulting Michael adducts were then subjected to an intramolecular conjugate addition over the vinyl sulfone moiety, thus rendering the final bicyclic sultams containing two stereocenters. The key point of this strategy relies on the use of vinyl sulfonamides as both, nitrogen nucleophiles and Michael acceptors. The use of phosphazene-derived bases avoided the racemization of the intermediate derivatives, rendering 6-membered ring bicyclic delta-sultams in enantiomerically enriched manner with a small erosion of enantiopurity. Anyway, after recrystallization, final sultams were obtained in almost enantiomerically pure form. Nevertheless, the enantioselective synthesis of either 5-membered ring products or benzofused derivatives was found to be out of the scope of our strategy. (Figure presented.).

Novel heterogenized asymmetric catalysts were synthesized by immobilizing preformed Ru catalysts on magnetite nanoparticles via the phosphonate functionality and were characterized by a variety of techniques, including TEM, magnetization, and XRD. These nanoparticle-supported chiral catalysts were used for enantioselective heterogeneous asymmetric hydrogenation of aromatic ketones with very high enantiomeric excess values of up to 98.0%. The immobilized catalysts were easily recycled by magnetic decantation and reused for up to 14 times without loss of activity and enantioselectivity. Orthogonal nature of the present catalyst immobilization approach should allow the design of other superparamagnetic nanoparticle-supported asymmetric catalysts for a wide range of organic transformations.

Application of 10049-08-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Conference Paper，once mentioned of 10049-08-8

Electrocatalysts, supported on carbon nanotubes (CNTs) were synthesized by two steps. In the first step, raw CNTs were refluxed with different concentrations of nitric acid, and in the second, metal precursors were attached to functionalized CNT surface with reducing agents. The concentration of nitric acid is important because oxidation introduces the functionality of the surface, which determines the morphology of the catalysts anchored on the support.

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 10049-08-8 is helpful to your research., Application of 10049-08-8

(Chemical Equation Presented) ROMPing around in water: Two well-defined, small-molecule olefin-metathesis catalysts (1 and 2) are introduced. While they are insufficiently stable to mediate most cross-metathesis reactions in water, these catalysts competently mediate ring-opening metathesis polymerization (ROMP) and ring-closing metathesis reactions in an aqueous environment.

The dinuclear complex [(eta6-C6H6)Ru(mu-N3)Cl]2 (1) is obtained by the reaction of [(eta6-C6H6)RuCl2]2 with sodium azide in ethanol. The benzene ruthenium beta-diketonato complexes of the general formula [(eta6-C6H6)Ru(L?L)Cl] {L?L = O,O?-acac (2); O,O?-bzac (3); O,O?-dbzm (4)} are obtained in methanol by the reaction of [(eta6-C6H6)RuCl2]2 with the corresponding beta-diketonates. These complexes further react with sodium azide in ethanol to yield complexes of the type [(eta6-C6H6)Ru(L?L)N3] [L?L = O,O?-acac (5); L?L = O,O?-bzac (6); L?L = O,O?-dbzm (7)]. The complexes 5-7 are obtained as well by treating 1 with sodium salts of beta-diketonates. These neutral benzene ruthenium azido complexes undergo [3+2] dipolar cycloaddition reaction with activated alkynes (MeO2CC{triple bond, long}CCO2Me, EtO2CC{triple bond, long}CCO2Et) or fumaronitrile (NCHC{double bond, long}CHCN) to yield the corresponding benzene ruthenium triazolato complexes; [(eta6-C6H6)Ru(O,O?-acac){N3C2(CO2Me)2}] (8), [(eta6-C6H6)Ru(O,O?-acac){N3C2(CO2Et)2}] (9), [(eta6-C6H6)Ru(O,O?-acac){N3C2HCN}] (10), [(eta6-C6H6)Ru(O,O?-bzac){N3C2HCN}] (11) and [(eta6-C6H6)Ru(O,O?-dbzm){N3C2HCN}] (12). These complexes are fully characterized on the basis of microanalyses, FT-IR and FT-NMR spectroscopy. The molecular structure of [(eta6-C6H6)Ru(O,O?- acac){N3C2(CO2C2H5)2}] (9) is confirmed by single crystal X-ray diffraction study.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a Article，once mentioned of 246047-72-3, name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium

Concise and high-yielding total syntheses of amphidinolides T1, T3, and T4 have been completed using an alkynyl macrolactone as a common late-stage intermediate. The required alpha-hydroxy ketone motif was installed by sequential alkyne hydrosilylation, epoxidation, and Fleming-Tamao oxidation. An oxonium ylide rearrangement formed the trisubstituted tetrahydrofuran core found in the natural products.

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.name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3
