2-(Trifluoromethyl)phenethyl alcohol (cas: 94022-96-5) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Name: 2-(Trifluoromethyl)phenethyl alcohol

Tuning Triplet Energy Transfer of Hydroxamates as the Nitrene Precursor for Intramolecular C(sp³)-H Amidation was written by Jung, Hoimin;Keum, Hyeyun;Kweon, Jeonguk;Chang, Sukbok. And the article was included in Journal of the American Chemical Society in 2020.Electric Literature of C9H9F3O This article mentions the following:

Reported herein is the design of a photosensitization strategy to generate triplet nitrenes and its applicability for the intramol. C-H amidation reactions. Substrate optimization by tuning phys. organic parameters according to the proposed energy transfer pathway led us to identify hydroxamates as a convenient nitrene precursor. While more classical nitrene sources, representatively organic azides, were ineffective under the current photosensitization conditions, hydroxamates, which are readily available from alcs. or carboxylic acids, are highly efficient in accessing synthetically valuable 2-oxazolidinones and 纬-lactams by visible light. Mechanism studies supported our working hypothesis that the energy transfer path is mainly operative. In the experiment, the researchers used many compounds, for example, 2-(4-(Trifluoromethyl)phenyl)ethanol (cas: 2968-93-6Electric Literature of C9H9F3O).

2-(4-(Trifluoromethyl)phenyl)ethanol (cas: 2968-93-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Electric Literature of C9H9F3O

And the article was included in Separation and Purification Technology in 2022.Name: Oct-1-en-3-ol This article mentions the following:

Lavender hydrolats are of low value due to its low aromatic compound concentration This work applied polydimethylsiloxane (PDMS) /ceramic composite membranes to enrich volatile aromatic compounds (linalool, terpinen-4-ol, 伪-terpineol, and camphor) of lavender hydrolats for improving antioxygenic property. The effect of operating conditions on the enrichment was systematically studied. The results showed that the fluxes of the four aromatic compounds increased with the increase of feed concentration in the binary simulation system. The enrichment factor of camphor increased more significantly than other components with the increase of flow velocity and the total flux was basically unchanged in pervaporation. The flux of lavender hydrolats was 254.84 g路m^-2路h^-1, the enrichment factors of linalool, terpinen-4-ol, 伪-terpineol, and camphor were found to be 5.64, 4.56, 2.59 and 15.31 at 40掳C, resp. The free radical scavenging rate of enriched lavender hydrolats was significantly improved.

Highly enantiomeric reduction of acetophenone and its derivatives by locally isolated Rhodotorula glutinis was written by Zilbeyaz, Kani;Kurbanoglu, Esabi B.. And the article was included in Chirality in 2010.SDS of cas: 171032-87-4 This article mentions the following:

Ninety isolates of microorganisms belonging to different taxonomical groups (30 bacteria, 20 yeast, and 40 fungi) were previously isolated from various samples. These isolates were screened as reducing agents for acetophenone 1a to phenylethanol 2a. It was found that the isolate EBK-10 was the most effective biocatalyst for the enantioselective bioreduction of acetophenone. This isolate was identified as Rhodotorula glutinis by the VITEK 2 Compact system. The various parameters (pH 6.5, temperature 32掳C, and agitation 200 rpm) of the bioreduction reaction was optimized, which resulted in conversions up to 100% with >99% enantiomeric excesses (ee) of the S-configuration. The preparative scale bioreduction of acetophenone 1a by R. glutinis EBK-10 gave (S)-1-phenylethanol 2a in 79% yield, complete conversion, and >99% ee. In addition, R.glutinis EBK-10 successfully reduced various substituted acetophenones. Chirality, 2010. 漏 2010 Wiley-Liss, Inc. In the experiment, the researchers used many compounds, for example, (S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4SDS of cas: 171032-87-4).

Some high-potential trithioether chelates of copper was written by Kanters, Rene P. F.;Yu, Ru;Addison, Anthony W.. And the article was included in Inorganica Chimica Acta in 1992.SDS of cas: 1122-71-0 This article mentions the following:

The linear quadridentate ligand 1,8-bis(2′-quinolyl)-3,6-dithiaoctane and the 3 quinquedentate ligands 1,9-bis(2′-pyridyl)-2,5,8-trithianonane, 1,9-bis(6′-methyl-2′-pyridyl)-2,5,8-trithianonane and 1,11-bis(2′-quinolyl)-3,6,9-trithiaundecane were prepared The deep green-blue Cu(II) chelates were characterized by optical and ESR spectroscopy and cyclic voltammetry. The 2 pyridyl chelates had similar tetragonal coordination about the Cu, with an equatorial N₂S₂ donor set, plus the 3rd thioether S bound axially. The most marked consequence of the pyridine 伪-methylation was that the Cu²⁺/⁺ reduction potential was raised by 鈭?00 mV; otherwise, the E_1/2 was consonant with previously advanced models for correlating redox potentials with ligand structural features. The pyridyl Cu(II) complexes were isolated as the tetrafluoroborate salts, whereas the quinolyl-Cu(II) chelates were rather redox unstable, in association with even more pos. Cu²⁺/⁺聽E_1/2 values, similar to that for dibromine reduction In the experiment, the researchers used many compounds, for example, 6-Methyl-2-pyridinemethanol (cas: 1122-71-0SDS of cas: 1122-71-0).

6-Methyl-2-pyridinemethanol (cas: 1122-71-0) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.SDS of cas: 1122-71-0

Light-Responsive, Shape-Switchable Block Copolymer Particles was written by Lee, Junhyuk;Ku, Kang Hee;Kim, Jinwoo;Lee, Young Jun;Jang, Se Gyu;Kim, Bumjoon J.. And the article was included in Journal of the American Chemical Society in 2019.Application of 60463-12-9 This article mentions the following:

A robust strategy is developed for preparing light-responsive block copolymer (BCP) particles in which shape and color can be actively controlled with high spatial and temporal resolution The key to achieving light-responsive shape transitions of BCP particles is the design and synthesis of surfactants containing light-active groups (i.e., nitrobenzyl esters and coumarin esters) that modulate the amphiphilicity and interfacial activity of the surfactants in response to light of a specific wavelength. These light-induced changes in surfactant structure modify the surface and wetting properties of BCP particles, affording both shape and morphol. transitions of the particles, for example from spheres with an onion-like inner morphol. to prolate or oblate ellipsoids with axially stacked nanostructures. In particular, wavelength-selective shape transformation of the BCP particles can be achieved with a mixture of two light-active surfactants that respond to different wavelengths of light (i.e., 254 and 420 nm). Through the use of light-emitting, photoresponsive surfactants, light-induced changes in both color and shape are further demonstrated. Finally, to demonstrate the potential of the light-triggered shape control of BCP particles in patterning features with microscale resolution, the shape-switchable BCP particles are successfully integrated into a patterned, free-standing hydrogel film, which can be used as a portable, high-resolution display. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Application of 60463-12-9).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 60463-12-9
