Ru K-edge XAS data indicate that second generation ruthenium-based olefin metathesis precatalysts (L = N-heterocyclic carbene) possess a more electron-deficient metal center than in the corresponding first generation species (L = tricyclohexylphosphine). This surprising effect is also observed from DFT calculations and provides a simple rationale for the slow phosphine dissociation kinetics previously noted for second-generation metathesis precatalysts.

Bio-derived furans such as 2-furfural (furfural), 5-hydroxymethyl-2-furfural (5-HMF) and 5-methyl-2-furfural (5-MF) were successfully transformed to a ketoacid, levulinic acid (LA), and diketones, 1-hydroxyhexane-2,5-dione (1-HHD), 3-hydroxyhexane-2,5-dione (3-HHD) and hexane-2,5-dione (HD), under moderate reaction conditions using water soluble and recyclable 8-aminoquinoline coordinated arene-ruthenium(ii) complexes. Under the optimized reaction conditions using 1 mol% catalyst in the presence of 12 equivalents of formic acid at 80-100 C, complete conversion of furfural to LA with high selectivity was achieved. Several experiments along with 1H NMR spectral studies are described which provide more insights into the mechanism underlying the transformation of furans to open ring components. Experiments performed using structural analogues of the active catalyst inferred a structure-activity relationship for the observed superior catalytic activity of the 8-aminoquinoline coordinated arene-ruthenium(ii) complex. Furthermore, due to the high aqueous solubility of the studied complexes, high recyclability, up to 4 catalytic runs, was achieved without any significant loss of activity. Molecular identities of the studied 8-aminoquinoline coordinated arene-ruthenium(ii) complex were also confirmed using single-crystal X-ray diffraction studies.

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.

The combination of enzymes with traditional chemical catalysts unifies the high selectivity of the former with the versatility of the latter. A major challenge of this approach is the difference in the optimal reaction conditions for each catalyst type. In this work, we combined a cofactor-free decarboxylase with a ruthenium metathesis catalyst to produce high-value antioxidants from bio-based precursors. As suitable ruthenium catalysts did not show satisfactory activity under aqueous conditions, the reaction required the use of an organic solvent, which in turn significantly reduced enzyme activity. Upon encapsulation of the decarboxylase in a cryogel, the decarboxylation could be conducted in an organic solvent, and the recovery of the enzyme after the reaction was facilitated. After an intermediate drying step, the subsequent metathesis in pure organic solvent proved to be straightforward. The synthetic utility of the cascade was demonstrated by the synthesis of the antioxidant 4,4?-dihydroxystilbene in an overall yield of 90 %.

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: 246047-72-3, you can also check out more blogs about246047-72-3

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, COA of Formula: C20H16Cl2N4Ru

This report documents the spectroscopic and photophysical properties of the complexes, Ru(bpdz)32+ and [Ru(bpy)2(bpdz)]2+, where bpdz = 3,3?-bipyridazine and bpy = 2,2?-bipyridine. Specifically, the complexes were characterized by UV-visible, emission, resonance Raman (RR), and transient resonance Raman (TR3) spectroscopic data, as well as lifetime measurements. The RR spectrum of the Ru(bpdz)32+ complex documents the characteristic modes of the coordinated ligand, whereas the RR spectra of the heteroleptic complex, [Ru(bpy)2(bpdz)]2+, obtained at judiciously chosen excitation wavelengths, reveal selective enhancement of either bpy modes or bpdz modes, depending upon the particular excitation wavelength, permitting definitive assignment of the observed electronic absorption bands and establishing the lowest energy electronic transition as having a Ru-to-bpdz charge-transfer character. The TR3 spectrum of the Ru(bpdz)32+ complex reveals the characteristic frequencies of the coordinated bpdz-· anion radical, as expected, whereas corresponding studies of the heteroleptic complex, [Ru(bpy)2(bpdz)]2+, reveal these characteristic bpdz-· modes in the absence of any modes attributable to bpy-· anion radicals, providing definitive evidence for the [Ru(III)(bpy)2(bpdz-·)]2+ formulation of the excited state of this complex. Lifetime measurements for both complexes, made over a wide range of temperatures and interpreted with a model derived from previous measurements made on a large number of similar complexes, indicate that the two complexes of interest decay by different nonradiative pathways resulting from thermal population of a ligand field 3dd and/or a lower lying 4th 3MLCT state.

8-Allylcoumarins are conveniently accessible through a microwave-promoted tandem Claisen rearrangement/Wittig olefination/ cyclization sequence. They serve as a versatile platform for the annellation of five- to seven-membered rings using ring-closing olefin metathesis (RCM). Furano-, pyrano-, oxepino- and azepinocoumarins were synthesized from the same set of precursors using Ru-catalyzed double bond isomerizations and RCM in a defined order. One class of products, pyrano[2,3-f]chromene-2,8-diones, were inaccessible through direct RCM of an acrylate, but became available from the analogous allyl ether via an assisted tandem catalytic RCM/allylic oxidation sequence.

Rapid and high yielding synthesis of medium ring lactams was made possible through the use of a benzoylurea auxiliary that serves to stabilize a cisoid amide conformation, facilitating cyclization. The auxiliary is released after activation under the mild conditions required to deprotect a primary amine, such as acidolysis of a Boc group in the examples given here. This methodology is a promising tool for the synthesis of medium ring lactams, macrocyclic natural products and peptides.
