Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Industrial & Engineering Chemistry Research called Efficient and Sustainable Hydrogenation of Levulinic Acid to γ-Valerolactone in Aqueous Phase over Ru/MCM-49 Catalysts, Author is Li, Wenlin; Li, Feng; Chen, Junwen; Betancourt, Luis E.; Tu, Chunyan; Liao, Mingjie; Ning, Xing; Zheng, Jiajun; Li, Ruifeng, which mentions a compound: 14898-67-0, SMILESS is Cl[Ru](Cl)Cl.[H]O[H], Molecular Cl3H2ORu, Synthetic Route of Cl3H2ORu.

The hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) is an essential reaction step to produce value-added renewable chems. and fuels. In this study, it is demonstrated that the dispersed state of metal and the acid properties of the support can be tuned directly in the synthesized stage for the Ru/MCM-49 catalysts. The average metal particle size of Ru was found at about 2.0 nm, and strong metal-support interaction was observed for the Ru/MCM-49(DP) catalyst. Mesopores presented can enhance the conversion rate for LA to GVL. The presence of a higher amount of Lewis acid sites can promote the ring closure esterification of the intermediate 4-HPA. High catalytic activity with a TOF value 3000 h-1, as well as excellent reusability, were achieved by Ru/MCM-49 (DP). The agglomeration of Ru particles and the coke formation was thought to be responsible for the deactivation of the catalyst.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhao, Wei; Wang, Ruyue; Wang, Yong; Feng, Junwei; Li, Cuncheng; Chen, Guozhu researched the compound: Ruthenium(III) chloride xhydrate( cas:14898-67-0 ).COA of Formula: Cl3H2ORu.They published the article 《Effect of LDH composition on the catalytic activity of Ru/LDH for the hydrolytic dehydrogenation of ammonia borane》 about this compound( cas:14898-67-0 ) in International Journal of Hydrogen Energy. Keywords: ruthenium LDH catalytic activity ammonia borane hydrolytic dehydrogenation. We’ll tell you more about this compound (cas:14898-67-0).

The hydrolytic dehydrogenation of ammonia borane (NH3-BH3, AB for short) in the presence of catalysts has been identified to be a safe and efficient way for hydrogen release. Understanding the dehydrogenation mechanism of AB is helpful and important to design efficient catalysts. So far, although the effects of various factors on dehydrogenation of AB have been studied, such as the noble metal particle size effect, crystal-phase effect and the support crystal plane effect, the effect of support composition on dehydrogenation of AB has rarely been reported yet. In this study, we choose composition-adjustable layered double hydroxide (MgAl-LDHs) as support for Ru nanoparticles, and use the as-prepared catalysts for comparing their catalytic activity towards the dehydrogenation of AB. The catalytic results demonstrate the catalytic activity of Ru/MgAl-LDHs is related to MgAl-LDHs composition, exhibiting a support-composition effect in the hydrolytic dehydrogenation of AB. Combining various characterizations, the different composition of MgAl-LDHs has an effect on the interaction between Ru nanoparticles and MgAl-LDHs, which directly affects the catalytic activity for the hydrolysis of AB. This study provides new important fundamental knowledge on the mechanism of AB hydrolysis over practical supported metal catalysts which can be used for a better catalyst design.

Six novel ruthenium(III) complexes of general formula [RuCl3(L)3] (1,3,5) and [RuCl3(H2O)(L)2] (2,4,6), where L stands for three different triazolopyrimidine-derived ligands, are reported. The compounds have been structurally characterized (IR, EPR, SCXRD), and their magnetic moments have been determined The single-crystal X-ray diffraction study revealed a slightly distorted octahedral geometry of the Ru(III) complexes with mer configuration in 1 and 5, and fac configuration in 3. In 2 and 4, three chloride ions are in mer configuration and the two triazolopyrimidines are oriented trans mutually with the water mol. playing the role of the sixth ligand. All complexes have been thoroughly screened for their in vitro cytotoxicity against human breast cancer cell line MCF-7, human cervical cancer cell line HeLa, and L929 murine fibroblast cells, uncovering among others that the most lipophilic complexes 5 and 6, containing the bulky ligand dptp (5,7-diphenyl-1,2,4-triazolo[1,5-a]pyrimidine), display high cytotoxic activity against MCF-7, and HeLa cells. Moreover, it was also revealed that during the interaction of the complexes 1-6 with the cancer MCF-7 cell line, reactive oxygen species are released intracellularly, which could indicate that they are involved in cell apoptosis. Furthermore, extensive studies have been carried out to reveal the mechanism by which complexes 1-6 interact with DNA, albumin, and apotransferrin. The biol. studies were complemented by detailed kinetic studies of the hydrolysis of the complexes in the pH range 5-8, to determine the stability of the complexes in solution Graphic abstract: Six novel ruthenium(III) complexes with triazolopyrimidine derivatives demonstrated the potential for use as anticancer agents by maintaining the toxic effect on MCF-7 and HeLa cells.[Figure not available: see fulltext.].

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Optimizing RuOx/TiO2 composite anodes for enhanced durability in electrochemical water treatments, published in 2021-02-28, which mentions a compound: 14898-67-0, Name is Ruthenium(III) chloride xhydrate, Molecular Cl3H2ORu, Application of 14898-67-0.

Metal oxide anode electrocatalysts are important for an effective removal of contaminants and the enhancement of electrode durability in the electrochem. oxidation process. Herein, we report the enhanced lifetime of RuOx-TiO2composite anodes that was achieved by optimizing the fabrication conditions (e.g., the Ru mole fraction, total metal content, and calcination time). The electrode durability was assessed through accelerated service lifetime tests conducted under harsh environmental conditions, by using 3.4% NaCl and 1.0 A/cm2. The electrochem. characteristics of the anodes prepared with metal oxides having different compositions were evaluated using cyclic voltammetry, electrocompositions impedance spectroscopy, and X-ray analyses. We noticed that, the larger the Ru mole fraction, the more durable were the electrodes. The RuOx-TiO2 electrodes were found to be highly stable when the Ru mole fraction was >0.7. The 0.8RuOx-0.2TiO2 electrode was selected as the one with the most appropriate compositions, considering both its stability and contaminant treatability. The electrodes that underwent a 7-h calcination (between 1 and 10 h) showed the longest lifetime under the tested conditions, because of the formation of a stable Ru oxide structure (i.e., RuO3) and a lower resistance to charge transfer. The electrode deactivation mechanism that occurred due to the dissolution of active catalysts over time was evidenced by an impedance anal. of the electrode itself and surface elemental mapping.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Excited states of the phthalimide chromophore and their exciton couplings: a tool for stereochemical assignments, published in 1998-11-25, which mentions a compound: 148857-42-5, mainly applied to phthalimide chromophore exciton coupling stereochem assignment, Safety of (S)-2-(3-Chloro-2-hydroxypropyl)isoindoline-1,3-dione.

Electronically excited states of the phthalimide chromophore were studied by linear dichroism (LD) of samples partially oriented in poly(vinyl alc.) films, magnetic CD (MCD), and CD spectroscopy. On the basis of the LD measurements, the low-energy tail (340-320 nm) of the 1st absorption band is assigned to an out-of-plane polarized n→π* transition (I). At higher energy, the electronic spectrum is resolved into contributions from 5 π→π* transitions: II (300 nm, long-axis polarized), III (275 nm, short-axis polarized), IV (235 nm, short-axis polarized), V (220 nm, long-axis polarized), and VI (∼210 nm, short-axis polarized). The results from semiempirical (INDO/S-CI) and ab initio (CIS/6-31+G(d)) MO calculations compare well with the proposed assignments of the excited states. Degenerate exciton interaction between elec.-dipole-allowed transitions of 2 phthalimide chromophores is observed in the electronic absorption spectra of the achiral bis-phthalimides I (n = 0-2) and in the CD spectrum of the chiral bis-phthalimide II (X = phthalimido). For the latter compound, the solid-state geometry was determined by x-ray diffraction. Good agreement between exptl. and computed CD spectra confirms that the coupled-oscillator exciton model provides the basis for a reliable nonempirical method for the assignment of absolute configuration for this class of compounds Nondegenerate exciton coupling between phthalimide and benzoate or Ph chromophores is borne out in the CD spectra of homochiral mols. II (X = OBz, Ph) with a rigid cyclohexane skeleton. Finally, the exciton-coupling method is used to make stereochem. assignments for the acyclic, conformationally flexible derivatives RCHMeCH2X (R = phthalimido throughout this abstract; X = R, OBz), RCH2CHMeOBz and RCH2CH(OBz)CH2Cl.

Product Details of 14898-67-0. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Scalable synthesis of high entropy alloy nanoparticles by microwave heating. Author is Qiao, Haiyu; Saray, Mahmoud Tamadoni; Wang, Xizheng; Xu, Shaomao; Chen, Gang; Huang, Zhennan; Chen, Chaoji; Zhong, Geng; Dong, Qi; Hong, Min; Xie, Hua; Shahbazian-Yassar, Reza; Hu, Liangbing.

High entropy alloy nanoparticles (HEA-NPs) are reported to have superior performance in catalysis, energy storage, and conversion due to the broad range of elements that can be incorporated in these materials, enabling tunable activity, excellent thermal and chem. stability, and a synergistic catalytic effect. However, scaling the manufacturing of HEA-NPs with uniform particle size and homogeneous elemental distribution efficiently is still a challenge due to the required critical synthetic conditions where high temperature is typically involved. In this work, we demonstrate an efficient and scalable microwave heating method using carbon-based materials as substrates to fabricate HEA-NPs with uniform particle size. Due to the abundant functional group defects that can absorb microwave efficiently, reduced graphene oxide is employed as a model substrate to produce an average temperature reaching as high as ~1850 K within seconds. As a proof-of-concept, we utilize this rapid, high-temperature heating process to synthesize PtPdFeCoNi HEA-NPs, which exhibit an average particle size of ~12 nm and uniform elemental mixing resulting from decomposition nearly at the same time and liquid metal solidification without diffusion. Various carbon-based materials can also be employed as substrates, including one-dimensional carbon nanofibers and three-dimensional carbonized wood, which can achieve temperatures of >1400 K. This facile and efficient microwave heating method is also compatible with the roll-to-roll process, providing a feasible route for scalable HEA-NPs manufacturing

Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Downshifted d-Band Center of Ru/MWCNTs by Turbostratic Carbon Nitride for Efficient and Robust Hydrogen Evolution in Alkali.

Ru, unlike Pt, is seldom considered as the effective electrocatalyst for hydrogen evolution reaction (HER) due to the strong binding of hydrogen species on metal surface as well as the serious metal bleaching. Herein, the amorphous turbostratic-phased carbon nitride (t-CNx) layer was utilized to downshift the d-band center of the Ru/multi-walled carbon nanotubes (Ru/MWCNTs) hybrids to achieve the optimized hydrogen species adsorption for subsequent efficient and stabilized hydrogen evolution in alkali. The catalysts with a low Ru loading of 8 wt % presented the high HER activity with a low overpotential of 39 mV for a catalytic c.d. of 10 mA cm-2, a small Tafel slope of 28 mV dec-1 and a stabilized catalytic performance over a period of 14 h in 1.0 M KOH, outperforming the 20 wt % Pt/C benchmarks. The thin t-CNx layer play dual roles: (1) as the modulator of electronic structures for Ru with lower d-band position for the enhanced activity and (2) as the protective layer to avoid the metal aggregation/bleaching and improve the catalytic stability of the hybrid catalysts subsequently.

Author is Rajesh, T.; Madhusudhan, G.; Mukkanti, K.; Rao, S. P. Narayana; Babu, K. Kishore.

The synthesis of the target compound was achieved [Linezolid, N-[[(5S)-3-[3-fluoro-4-(4-morpholinyl)phenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide] by two pathways. The synthetic route in both ways involves preparation of 2-[(R)-3-(3-fluoro-4-morpholinophenyl)amino-2-hydroxypropyl]-1,3-isoindolinedione (I) as a key intermediate starting from (S)-epichlorohydrin and phthalimide. One of these methods involves a direct N-alkylation of 3-fluoro-4-morpholinoaniline with 2-[(S)-3-chloro-2-hydroxypropyl]-1,3-isoindolinedione. Alternatively, I was prepared by a one-pot three-step sequence via 2-[[(S)-2-oxiranyl]methyl]-1,3-isoindolinedione.

Electric Literature of Cl3H2ORu. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Light-driven synthesis of sub-nanometric metallic Ru catalysts on TiO2. Author is Wojciechowska, Joanna; Gitzhofer, Elisa; Grams, Jacek; Ruppert, Agnieszka M.; Keller, Nicolas.

A one-step room temperature photo-assisted synthesis has been implemented in liquid phase and under solar light for preparing highly dispersed TiO2 supported metallic Ru catalysts, with no need of final thermal treatment, external hydrogen, or chem. reductant. Whether RuCl3 chloride or Ru(acac)3 acetylacetonate precursor salt was used, sub-nanometric metallic Ru nanoparticles were synthesized on TiO2 with a sharp size distribution, the high dispersion and the metallic nature of the nanoparticles being evidenced by transmission electron microscopy and XPS. However, the use of the chloride salt was proposed to be more suitable for preparing Ru/TiO2 catalysts, due to the lower photodeposition efficiency observed with acetylacetonate, that did not allow to synthesize Ru nanoparticles with a loading higher than 1 weight%. Different reaction mechanisms have been proposed for explaining the behavior of both TiO2-salt systems during the Ru nanoparticle synthesis, involving resp., both holes and electrons charge carriers in oxidation and reduction steps with acetylacetonate, and the sole photogenerated electrons with chloride.
