Performance of 31 DFT methods in thermochemistry of olefin metathesis involving the model catalyst (PH3)2(Cl) 2RuCH2 is studied using the CCSD(T) reference energies. The best methods are M06, omegaB97X-D and PBE0, followed by MPW1B95, LC-omegaPBE, M05-2X and B1B95. Among 20 functionals tested in reproduction of experimental PCy3 dissociation energy for the Grubbs catalyst (H 2IMes)(PCy3)(Cl)2RuCHPh, the M06-class and M05-2X methods are most accurate. omegaB97X-D overestimates the dissociation energy, whereas MPW1B95, LC-omegaPBE, PBE0 and B1B95 underestimate it, similarly to other methods, which give larger errors. LC-omegaPBE, B1B95, MPW1B95 and PBE0 provide the best geometries.

(Chemical Equation Presented) A real step-saver: A single ruthenium-carbene complex catalyzes a sequence of two reactions, namely, a metathesis reaction (ring-closing or cross metathesis) and subsequent dihydroxylation of the newly formed double bond. A variety of cyclic and acyclic cis-diols were prepared in good yields (see scheme). This new methodology provides an interesting alternative to the pinacol coupling.

In a Article，once mentioned of 10049-08-8, Quality Control of: Ruthenium(III) chloride

A mild formation of transient acylnitroso intermediates using a copper chloride catalyst and 1 atm of air as the terminal oxidant is described. The mild reaction conditions enable the inter- and intramolecular acylnitroso ene reaction with a wide range of functionalized alkene partners, as well as the first asymmetric variant. Notably, this transformation provides a practical and operationally simple method for effecting allylic amidation using an environmentally benign oxidant and a readily abundant transition metal.

Using an adaptable A ring building block, the B ring was annulated by (4 + 2)-cycloaddition and the C ring by ring-closing metathesis. The angular methyl groups were attached by electrophilic cyclopropanation-ring opening.

The reaction of [(arene)MCl2]2 with pyridylpyrazolyl ligands (L1 and L2) in the presence of ammonium hexafluorophosphate leads to formation of cationic complexes having the general formula [(arene)M(L)Cl]PF6 {M = Ru, arene = p-cymene (1, 4); Cp*, M = Rh (2, 5); Cp*, M = Ir (3, 6); L = 2-(1H-pyrazol-1-yl)pyridine (L1), 2-(3,5-dimethyl-1H-pyrazol-1-yl)pyridine (L2)}. Similarly the reaction of [CpRu(PPh3)2Cl] and [(ind)Ru(PPh3)2Cl] (ind = eta5-C9H7) with L1 and L2 yielded cationic complexes which have been formulated as [(Cp/ind)Ru(L)PPh3]PF6 (7?10). All these complexes were characterized by analytical and spectroscopic techniques. The pyridylpyrazolyl ligands coordinated metal through pyridyl and pyrazolyl nitrogens forming a six-membered metallacycle. The ligands as well as the complexes were evaluated for their in vitro antibacterial activity by agar well diffusion method against two Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and two Gram positive bacteria (Staphylococcus aureus and Bacillus thuriengiensis). Results show that the ligands and the complexes have significant antibacterial activity against Gram negative bacteria. (Figure presented.).

(Chemical Equation Presented) Small-molecule natural products are presumably often biosynthesized with a view to optimizing their ability to bind to strategic proteins or other biomolecular targets. Although the ultimate setting in which a drug must function may be very different, the use of such natural products as lead compounds can serve as a significant head start in the hunt for new agents of clinical value. Herein we reveal the synergistic relationship between chemical synthesis and drug optimization in the context of our research program around the epothilones: how synthesis led to the discovery of more-potent epothilone derivatives, and discovery inspired the development of new synthetic routes, thus demonstrating the value of target-directed total synthesis in the quest for new substances of material clinical benefit.

Bulk solid samples of various ratios of the cyclometalated arene ruthenium diastereomers (S)Ru- and (R)Ru-[(eta6-C6H6)Ru(C 6H4-2-(R)-CH(Me)NMe2)PMe2Ph] +PF6- (3a/3b), of which the configurational stability at the metal center has been established by classical solution techniques, have been analyzed by the 13C cross-polarization magic angle spinning (CP-MAS) and 31P MAS NMR. The spectra obtained allowed us to detect both isomers and to estimate their respective proportions by 31P spectra. This technique was applied to a bulk solid sample of the diastereomers (S)Ru- and (R)Ru-[(eta6-C6H 6)Ru(C6H4-2-(R)-CH(Me)NMe 2)NCMe]+PF6- (1a/1b), which were shown to be configurationally labile by classical solution experiments. Detection of isomer 1a only in the resulting 13C CP-MAS NMR spectrum demonstrated that there has been epimerization of 1b to 1a during crystallization, thus confirming the configurational lability at the metal center.

Olefin cross metathesis on solid support under a variety of conditions is described. A comprehensive analysis considering diverse factors governing the reaction outcome gives a series of patterns for the application of this useful methodology in organic synthesis. If the intrasite reaction is not possible, homodimerization of the soluble olefin is crucial. When the homodimer is less reactive than its monomer, reaction outcome depends on the homodimerization rate, which, in turn, depends on the precatalyst used and the reaction conditions. If the site-site interaction is a feasible process, the cross metathesis product is obtained exclusively when the newly-formed double bond is resilient to further metathetic events. Taking into account these considerations, we have demonstrated that excellent results in terms of cross metathesis coupling can be obtained under the optimized conditions, and that microwave irradiation is also an interesting alternative for the development of a practical and energy-efficient cross metathesis on solid support.

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.Application In Synthesis of (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, you can also check out more blogs about301224-40-8

Catalytic chemo- and enantioselective generation of 1,3-disubstituted allyl-Cu complexes from a Cu-H addition to 1,3-dienes followed by in situ reactions with aldimines to construct homoallylic amines is presented. The method is distinguished by an unprecedented pathway to generate enantiomerically enriched allyl-Cu species, allowing reactions with a wide range of aldimines in high chemo-, site-, diastereo-, and enantioselectivity. Functionalization provides useful building blocks that are otherwise difficult to access.
