Rousseva, Sylvia et al. published their research in Journal of Physical Chemistry C in 2020 | CAS: 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. 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 111-77-3

Reaching a Double-Digit Dielectric Constant with Fullerene Derivatives was written by Rousseva, Sylvia;Besten, Hugo den;van Kooij, Felien S.;Doting, Eva L.;Doumon, Nutifafa Y.;Douvogianni, Evgenia;Anton Koster, L.

The dielec. constant (εr) of organic semiconductors is a key material parameter for improving device performance in the field of organic electronics. However, the effect of the dielec. constant on the electronic and optoelectronic properties of materials remains unclear due to the scarcity of known organic semiconductors with an εr value higher than 6. Herein, the optical and electronic properties of a homologous series of fullerene derivatives with high εr are studied. The low frequency (<106 Hz) εr is extracted from the capacitance measured using impedance spectroscopy, and the effect of length (n) and geometrical arrangement of the polar ethylene glycol (EG) side chains is investigated. The εr is found to correlate with length for the sym. Bingel adducts, whereas for the unsym. branched-EG chain adducts there is no significant difference between the two EG chain lengths. For BTrEG-2, the εr reaches 10, which is an unprecedented value in monoadduct fullerene derivatives These materials open up new possibilities of studying the effect of εr in organic electronic devices such as organic photovoltaics, organic thermoelecs., and organic field-effect transistors. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Related Products of 111-77-3).

Nafikova, E. P. et al. published their research in Russian Chemical Bulletin in 2014 | CAS: 605-94-7

2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) 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, 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. 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.Product Details of 605-94-7

Chlorination of phenoxyacetic acid and several of its meta- and para-substituted derivatives by N-chloro-3-methyl-2,6-diphenylpiperidin-4-one yields monochlorinated product through a direct rate limiting attack at the ortho-carbon. The reaction is first order with respect to [substrate] and [oxidant]. Increase in [H+] and [Cl–] increases the rate of reaction. The reaction rate does not show any significant change with an increase in ethanol content of the medium. The reaction is inhibited by added piperidone.

High-performance lithium-metal batteries are achieved by using a glyme-based electrolyte enhanced with a LiNO3 additive and a LiFePO4 cathode. An optimal electrolyte formulation is selected upon detailed anal. of the electrochem. properties of various solutions formed by dissolving resp. lithium bis(fluorosulfonyl)imide (LiFSI), lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), and lithium bis(pentafluoroethanesulfonyl)imide (LiBETI) either in diethylene glycol di-Me ether or in triethylene glycol di-Me ether and by adding LiNO3. A thorough investigation shows evidence of efficient ionic transport, a wide stability window, low reactivity with lithium metal, and cathode/electrolyte interphase characteristics that are strongly dependent on the glyme chain length. The best Li/LiFePO4 battery delivers 154 mAh g-1 at C/3 (1 C=170 mA g-1) without any decay after 200 cycles.

Yeh, Li-Hsuan et al. published their research in Organic Letters in 2019 | CAS: 5367-32-8

3-Methyl-4-nitroanisole (cas: 5367-32-8) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. 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.Electric Literature of C8H9NO3

Short, efficient routes to several 7,8-dimethoxy-1-haloalkyl-1,3,4,5-tetrahydro-2-benzoxepins were developed. These benzoxepins were prepared by the Lewis acid-catalyzed condensation of Cl(CH2)3CH(OEt)2 or BrCH2CH(OEt)2 with 3,4-(MeO)2C6H3(CH2)3OH. This condensation was facilitated by Me substitution on the propanol. In an alternate route, 3,4-(MeO)2C6H3CH2CH2CO2Et was acylated with ClCH2CH2COCl. The adduct was reduced with LiAlH4.
