Toward solvent-free continuous-flow electrochemically mediated carbon capture with high-concentration liquid quinone chemistry was written by Diederichsen, Kyle M.;Liu, Yayuan;Ozbek, Nil;Seo, Hyowon;Hatton, T. Alan. And the article was included in Joule in 2022.Product Details of 111-77-3 This article mentions the following:

The recent interest in electrochem. methods of carbon capture has thus far focused either on static adsorbent-type electrodes, which require complex gas distribution and release engineering, or aqueous flowing systems, which allow capture over large, distributed areas and release from a centralized point, but require large amounts of water. Here, we advance a concept for a flowing, electrochem. mediated carbon capture process by utilizing redox-active mols. that are liquid at room temperature, avoiding the need for large water feeds. To demonstrate the potential of this concept, we employed a liquid quinone sorbent with added glyme to aid in salt solubilization coupled to a ferrocene-derived counter electrolyte. We achieved good electrochem. stability and continuous capture and release of CO₂ in a full bench scale process. Our concept for continuous-flow electrochem. CO₂ capture suggests many areas for further study, particularly the need for novel cell concepts and designs. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Product Details of 111-77-3).

2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Product Details of 111-77-3

Synthesis and antitumor activity of A-ring modified hexacyclic analogs of camptothecin was written by Li, Dizao;Wang, Cunying;Pan, Xiandao;Liu, Hongyan;Fu, Zhaodi;Wu, Song. And the article was included in Yaoxue Xuebao in 2005.Name: 2-(4-Methoxyphenoxy)acetic acid This article mentions the following:

The biol. activity of A-ring modified analogs of camptothecin was improved. A-ring modified camptothecins were synthesized from 10-hydroxycamptothecin or 7-ethyl-10-hydroxycamptothecin (SN-38) in 3 or 4 steps. Their cytotoxicity was evaluated using MTT assay, and their in-vivo antitumor activity against mouse liver cancer H22 was tested. Five hexacyclic camptothecins are target compounds, and ten camptothecin derivatives are new compounds The modification of an 1,4-oxazin-2-one ring-fused with positions 9 and 10 of A-ring will reduce the antitumor activity of camptothecins. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Name: 2-(4-Methoxyphenoxy)acetic acid).

2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Name: 2-(4-Methoxyphenoxy)acetic acid

An efficient synthesis of indole-2-acetic acid methyl esters: methyl 5-methoxyindole-2-acetate (1H-indole-2-acetic acid, 5-methoxy-, methyl ester) was written by Modi, Sandeep P.;Oglesby, R. Christopher;Archer, Sydney. And the article was included in Organic Syntheses in 1995.Synthetic Route of C8H9NO3 This article mentions the following:

A general synthetic method for the preparation in 3 steps of indole-2-acetic acid Me esters from o-nitrophenylacetic acids is described. The overall yields are 30-40% and the reactions can be carried out on a large scale. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Synthetic Route of C8H9NO3).

3-Methyl-4-nitroanisole (cas: 5367-32-8) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Synthetic Route of C8H9NO3

Cobalt-catalyzed cyclization of benzamides with alkynes: a facile route to isoquinolones with hydrogen evolution was written by Manoharan, Ramasamy;Jeganmohan, Masilamani. And the article was included in Organic & Biomolecular Chemistry in 2018.Application of 16356-02-8 This article mentions the following:

The reaction of benzamides with alkynes assisted by an 8-aminoquinoline ligand in the presence of Co(OAc)₂·4H₂O and pivalic acid under an air atm. provided isoquinolone derivatives in good to excellent yields. In this reaction, the active Co(III) species is regenerated by the reaction of Co(I) species with pivalic acid under an air atm. with hydrogen evolution. The proposed mechanism was supported by competition experiments, deuterium labeling studies, radical scavenger experiments and kinetic studies. In the experiment, the researchers used many compounds, for example, 1,4-Dimethoxy-2-butyne (cas: 16356-02-8Application of 16356-02-8).

1,4-Dimethoxy-2-butyne (cas: 16356-02-8) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Application of 16356-02-8

Few-nm-sized, phase-pure Au₅Sn intermetallic nanoparticles: synthesis and characterization was written by Osugi, Satoshi;Takano, Shinjiro;Masuda, Shinya;Harano, Koji;Tsukuda, Tatsuya. And the article was included in Dalton Transactions in 2021.Synthetic Route of C8H18O4 This article mentions the following:

Nanoparticles of intermetallic compounds have attracted much interest because they can exhibit novel electronic and catalytic properties due to their specific crystal structure, ordered at. arrangement, and quantum effect. Here, gold-tin (AuSn) bimetallic nanoparticles with various mixing ratios were prepared by a co-reduction method using various protective agents (e.g., polymer, amine, phosphine, carboxylic acid, and thiol). Powder X-ray diffractometry and transmission electron microscopy revealed that few-nm-sized, phase-pure Au₅Sn intermetallic nanoparticles (IMNPs) were successfully synthesized when Au³⁺ and Sn²⁺ precursors with a ratio of 6 : 4 were co-reduced in the presence of oleylamine. The Au₅Sn IMNPs thus prepared did not exhibit localized surface plasmon resonance, in contrast to pure Au nanoparticles of comparable sizes. This suggests that interband transition dominates the optical response due to an increase in the d. of states near the Fermi level by introducing Sn. The Au₅Sn IMNPs supported on mesoporous silica (SBA-15) catalyzed the aerobic oxidation reaction of indanol. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Synthetic Route of C8H18O4).

2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Synthetic Route of C8H18O4

A New Route to E-Stilbenes through the Transition-Metal-Free KOtBu/DMF-Promoted Direct Coupling of Alcohols with Phenyl Acetonitriles was written by Liu, Xiaoping;Sotiropoulos, Jean-Marc;Taillefer, Marc. And the article was included in European Journal of Organic Chemistry in 2022.Related Products of 105-13-5 This article mentions the following:

An alternative route to synthesize alkenes, based only on the KOtBu/DMF promoted activation and direct coupling of alcs. with Ph acetonitriles, was reported. A variation allowing, through a Csp³-Csp³ bond formation, the selective synthesis of N-Heteroarenes was also described. A mechanism for the olefination pathway proceeding via an original activation of alcs. under alkyl formates was provided. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Related Products of 105-13-5).

(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Related Products of 105-13-5

Study on hydrothermal liquefaction of antibiotic residues for bio-oil in ethanol-water system was written by Yang, Jian;Hong, Chen;Li, Zaixing;Xing, Yi;Zhao, Xiumei. And the article was included in Waste Management (Oxford, United Kingdom) in 2021.Safety of 2-(2-Methoxyethoxy)ethanol This article mentions the following:

In this study, antibiotic residue was converted into bio-oil by hydrothermal liquefaction (HTL) in subcritical or supercritical ethanol/water system. The bio-oil yield increased firstly as the ethanol/water ratio < 1:1, reaction temperature < 280°C, residence time < 150 min, and thereafter decreased. However, the bio-oil yield continuously decreased with a plunge at 15% as the solid/liquid ratio increased. The change tendency of O/C, H/C and N/C of bio-oil indicated different reaction mechanism of HTL. The addition of ethanol significantly promoted the esterification reaction, leading to increase of aliphatics content of bio-oil, especially branched long-chain aliphatics. Comprehensively considering the bio-oil yield, production cost, higher heating value (HHV) and chem. composition, the optimal process parameters of HTL were obtained as follows: ethanol/water ratio of 1:1, reaction temperature of 280°C, residence time of 150 min, and solid/liquid ratio of 15%, under which the bio-oil yield was 33.29 wt%, HHV was 33.47 MJ/kg, and the main compositions of bio-oil were esters (>48%). In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Safety of 2-(2-Methoxyethoxy)ethanol).

Novel synthetic methods for phenoxathiins e.g., I and phenothiazines II (R = H, OMe, morpholin-4-yl, etc.) by aryne reactions e.g., 2-(trimethylsilyl)phenyl triflate are disclosed. Here, it was found that phenoxathiins e.g., I were efficiently prepared by the reaction between aryne intermediates and S-(2-hydroxyaryl) 4-toluenethiosulfonates R¹-2-OHC₆H₃STs (R¹ = H, 5-Me, 4-OMe).

Monofluoro Analogs of Eugenol Methyl Ether as Novel Attractants for the Oriental Fruit Fly was written by Khrimian, Achot P.;DeMilo, Albert B.;Waters, Rolland M.;Liquido, Nicanor J.;Nicholson, Jesse M.. And the article was included in Journal of Organic Chemistry in 1994.COA of Formula: C11H16O3 This article mentions the following:

Monofluoro analogs of eugenol Me ether as potential attractants for the Oriental fruit fly (Bactrocera dorsalis, Hendel) were synthesized using selective fluorination reactions: electrophilic hydro- and iodofluorination, fluorodehydroxylation with (diethylamido)sulfur trifluoride (DAST), and Wittig fluoroolefination through the stabilized ylides. Unusual reduction of the double bond was detected in a reaction of Me eugenol with pyridinium poly(hydrogen fluoride). Bis[(3,4-dimethoxyphenyl)alkyl] carbonates were identified as the novel nucleophilic substitution products of the intermediate generated from the reaction of 3,4-dimethoxybenzenealkanols with DAST. Reductive desulfonylation of (Z)-3,4-(MeO)₂C₆H₃CH₂CH:CFSO₂Ph with sodium amalgam afforded 3,4-(MeO)₂C₆H₃CH₂CH:CHF (E/Z = 85:15) which was highly attractive to the Oriental fruit fly.
