A method for isomerizing a maleate, or a maleate containing a 2-propenyloxy group in the molecule at a high selectivity is provided which employs an isomerizing catalyst containing a Group VIII element. This method produces a fumarate, or a fumarate containing a 1-propenyloxy group in a high yield, which is useful in the fields of resin source materials and plasticizer. This method gives high-purity fumarates containing no catalyst residue by use of a heterogeneous catalyst which is readily separable and non-corrosive.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: Dichlorodicarbonylbis(triphenylphosphine)ruthenium(II). In my other articles, you can also check out more blogs about 14564-35-3

In an article, published in an article, once mentioned the application of 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer,molecular formula is C12H12Cl4Ru2, is a conventional compound. this article was the specific content is as follows.Formula: C12H12Cl4Ru2

A series of p-cymene ruthenium dichloro complexes containing isonicotinic ester ligands, [(arene)RuCl2NC5H4-4-COO-C 6H4-p-O-(CH2)n-CH3] (n = 1: 1, n = 3: 2, n = 5: 3, n = 7: 4, n = 9: 5, n = 11: 6, n = 13: 7, n = 15: 8), were prepared from p-cymene ruthenium dichloro dimer and the corresponding isonicotinic ester ligand. The single-crystal X-ray analysis of 1 shows the molecule to adopt the usual pseudo-tetrahedral piano-stool geometry, the isonicotinic ester ligand being coordinated through the nitrogen atom. The cytotoxicity of all complexes and of the free ligands was studied towards human ovarian cancer cells; high activities were observed only for n = 9 (presenting a chain with ten carbon atoms), both as far as the free ligands and the complexes are concerned. Based on this result, a new isonicotinic ester ligand with a C10 substituent containing a terminal alcohol function, NC 5H4-4-COO-C6H4-p-O-(CH 2)10-OH, was synthesized by a four-step method, and arene ruthenium complexes thereof, [(arene)RuCl2NC5H 4-4-COO-C6H4-p-O-(CH2) 10-OH] (arene = C6H6: 9a, arene = p-MeC 6H4Pri: 9b, arene = C6Me 6: 9c) were prepared. The complexes 9a and 9b show indeed remarkable anticancer activities, the IC50 values for human ovarian cancer cells being in the submicromolar range. The highest cytotoxicity was observed for complex 9b, with IC50 values of 0.18 muM for A2780 and 3.04 muM for the cisplatin-resistant mutant A2780cisR.

Electric Literature of 301224-40-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a Article，once mentioned of 301224-40-8

Hydroxide ion is shown to be a potent disruptor of Ru-catalyzed olefin metathesis, in a study of the Hoveyda catalyst HII. Addition of [NnBu4][OH] immediately terminates metathesis via HII, an effect traced to formation of bis(hydroxide) complex HII-OH. The latter was synthesized for direct study. HII-OH initiates very slowly on reaction with olefins, and decomposes in the first cycle of metathesis. Computational analysis reveals rapid bimolecular coupling between HII-OH and its four-coordinate methylidene derivative. Importantly, fully decomposed catalyst also accelerates decomposition of HII-OH. The H-bonding capacity of the hydroxide ligand is proposed as a powerful driving force for degradation.

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 301224-40-8 is helpful to your research., Synthetic Route of 301224-40-8

Reaction of benzaldehyde thiosemicarbazones [H2LR, where H 2 stands for the two protons, the hydrazinic proton, and the phenyl proton at the ortho position, with respect to the imine function and R (R = OCH3, CH3, H, Cl, and NO2) for the para substituent] with [Ru(PPh3)2(CO)2Cl 2], carried out in refluxing ethanol, afforded monomeric complexes of type [Ru(PPh3)2(CO)(HLR)(H)]. The crystal structure of the [Ru(PPh3)2(CO)(HLNO2)(H)] complex was determined. The thiosemicarbazone ligand is coordinated to the ruthenium center as a bidentate N,S-donor ligand forming a four-membered chelate ring. When the reaction of the thiosemicarbazones with [Ru(PPh3)2(CO) 2Cl2] was carried out in refluxing toluene, a family of dimeric complexes of type [Ru2(PPh3) 2(CO) 2(LR)2] were obtained. The crystal structure of [Ru 2(PPh3)2(CO)2(LCl)2] was determined. Each thiosemicarbazone ligand is coordinated to one ruthenium atom, by dissociation of the two protons, as a dianionic tridentate C,N,S-donor ligand, and at the same time the sulfur atom is also bonded to the second ruthenium center. 1H NMR spectra of the complexes of both types are in excellent agreement with their compositions. All the dimeric and monomeric complexes are diamagnetic (low-spin d6, S = 0) and show intense absorptions in the visible and ultraviolet regions. Cyclic voltammetry of the [Ru(PPh3)2(CO)(HLR)(H)] and [Ru2(PPh 3)2-(CO)2(LR)2] complexes show the ruthenium(II)-ruthenium(III) oxidation within 0.48-0.73 V vs. SCE followed by a ruthenium(III)-ruthenium(IV) oxidation within 1.09-1.47 V vs. SCE. Potentials of both the oxidations are found to correlate linearly with the electron-withdrawing character of the substituent R. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

The reaction of half-sandwich complexes of ruthenium, rhodium, and iridium with amino-substituted 3-hydroxy-2-pyridone ligands in aqueous solution gives monomeric O,O?-chelate complexes. Upon addition of base, the complexes assemble to form trimeric metallamacrocycles, as evidenced by NMR spectroscopy and single-crystal X-ray analyses. The macrocycles are able to act as highly selective receptors for lithium ions. The binding constants depend on the nature of the half-sandwich complex, the ligand, and the pH. With a commercially available (cymene)Ru complex, a receptor with a Li+ binding constant of Ka = 5.8 (±1.0) × 104 M-1 and a Li+-Na+ selectivity of 10 000:1 can be obtained. The fact that the assembly process of the receptor is pH-dependent can be used to detect the presence of lithium ions by a pH measurement. Furthermore, it is possible to transduce the binding of Li+ into a change of color by means of a chemical reaction with FeCl3. This allows the detection of Li + in the pharmacologically relevant concentration range of 0.5-1.5 mM by the “naked eye”.

Five new complexes of the type [RuCl2(NHC)(eta6-arene)] (4, 5, and 6) and [RuCl(NHC)(eta6-arene)(PR3)]Cl (7 and 8) (NHC[dbnd]N-heterocyclic carbene = bmim, emim; arene = benzene, p-cymene; PR3 = PPh3 or pta = 1,3,5-triaza-7-phosphaadamantane) were synthetized and applied as catalysts (together with the known [RuCl2(bmim)(eta6-p-cymene)] (3) with and without added PPh3) in racemization of optically active secondary alcohols in toluene. The highest catalytic activity, TOF = 9.3 h?1 (ee as low as 1.3% in 4 h at 95 C) was observed in racemization of (S)-1-phenylethanol with a catalyst (4 mol%) prepared in situ from 3 and 1 equivalent of PPh3. It is of practical significance that formation of acetophenone byproduct was suppressed to 3.5% by 17% v/v isopropanol in toluene. DFT calculations revealed that the rate determining step in the suggested reaction mechanism was the agostic coordination of hydrogen on the chiral carbon atom of the alcohol substrate.
