Pyridine-based chiral smectogens: effects of polar end groups on liquid crystal properties was written by Vardar, Deniz;Akdas Kilic, Huriye;Ocak, Hale;Jeannin, Olivier;Camerel, Franck;Eran, Belkiz Bilgin. And the article was included in Liquid Crystals in 2021.COA of Formula: C13H12O2 The following contents are mentioned in the article:

In this study, novel chiral pyridine-based rod-like mesogens, consisting of a chloro or bromo group substituted pyridine head core which is connected to one or two aromatic rings through ester linkers and a flexible (S)-2-methylbutoxy or (S)-3,7-dimethyloctyloxy chiral end chain have been synthesized. The liquid crystal properties of new compounds were investigated by various exptl. techniques such as DSC, POM and SAXS. Depending of the nature of the halogen end group, the derivatives with two aromatic rings are non-mesogenic compounds whereas a smectic A phase (SmA) enantiotropically occurs for the members with three aromatic rings of the series. Addnl., chloro group substituted compound composed of three aromatic rings carrying a (S)-2-methylbutoxy end chain exhibits an enantiotropic chiral nematic phase (N*). This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2COA of Formula: C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.COA of Formula: C13H12O2

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Formula: C13H12O2

ortho- and meta-Selective C-H Activation and Borylation of Aromatic Aldehydes via in situ Generated Imines was written by Bisht, Ranjana;Chattopadhyay, Buddhadeb. And the article was included in Synlett in 2016.Formula: C14H19BO4 The following contents are mentioned in the article:

A ligand-controlled discovery of ortho and meta C-H borylation of aromatic aldehydes is described. In both cases, an amine is used and it was proposed that ortho borylation could be realized using tert-butylamine as the traceless protecting/directing group and meta borylation undergoes via an electrostatic interaction and a secondary interaction between the ligand of the iridium catalyst and the substrate. Remarkably, these electrostatic interactions and secondary B-N interactions offer a unique and unprecedented guiding factor for the meta-selective C-H activation/borylation of benzaldehydes. This is the first example for the C-H activation and functionalization where the ortho and meta position of a substrate has selectively been functionalized, which open a new chapter in electrophilic aromatic substitution. This study involved multiple reactions and reactants, such as 5-Methoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (cas: 1132669-90-9Formula: C14H19BO4).

Ring opening and skeletal reconstruction of 3-vinyl benzofuranone-chromone synthons: catalyst-free access to skeletally-diverse 2-pyridone and optically active imidazoline derivatives was written by Wang, Wei-Na;Liu, Ren-Ming;Zhang, Lei;Liu, Xiong-Li;Dai, Yi-Feng;Yu, Zhang-Biao;Peng, Li-Jun. And the article was included in Organic & Biomolecular Chemistry in 2022.Product Details of 109-85-3 The following contents are mentioned in the article:

Herein the first example of ring opening and skeletal reconstruction of 3-vinyl benzofuranone-chromones as versatile synthons, which could react with ammonia or primary aliphatic amines as binucleophiles, for the eco-friendly and atom-economical synthesis of diverse and functionalized 2-pyridones with potential biol. activity in good to excellent yields (77-93%) was reported. When using optically active 1,2-diphenylethylenediamine as the binucleophile, the in situ generated 2-pyridone intermediates were successfully transformed to novel optically active functionalized imidazoline derivatives with high efficiency (up to 87% yield). In particular, this was the first report on the catalyst-free intramol. cyclization occurring between an amide and a primary aliphatic amine for the construction of imidazoline mols. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Product Details of 109-85-3).

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Product Details of 109-85-3

Effect of chemical formulations for uranium decontamination by chemical gels was written by Jung, Chong-Hun;Choi, Wang-Kyu;Moon, Jei-Kwon. And the article was included in Asian Journal of Chemistry in 2016.Name: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

A review. The decontamination and rheol. behaviors of chem. gels prepared in a Ce(IV)-HNO₃ or HNO₃ based solution for tile surfaces contaminated with uranium radionuclides were investigated. Gelling agents were prepared by adding PEG-based non-ionic coviscosifiers into a stable pyro Si viscosifier. Dispersion of gelling agents in a Ce(IV)-HNO₃ solution or HNO₃ solution produces a chem. decontamination gel. The order of removal percentage of uranium with various co-viscosifiers was diethylene glycol hexyl ether (DGHE) > tripropylene glycol dodecyl ether (TPGDDE) > tripropylene glycol Bu ether (TPGBE).This is considered to be due to the difference in the length of hydrophobic alkyl chains of coviscosifier and initial activity level of contaminated specimens. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Name: 2-(2-(Hexyloxy)ethoxy)ethanol).

Temperature Dependence of Emulsion Morphologies and the Dispersion Morphology Diagram. 3. Inversion Hysteresis Lines for Emulsions of Middle and Bottom Phases of the System C₆H₁₃(OC₂H₄)₂OH/n-Tetradecane/”Water” was written by Smith, Duane H.;Sampath, Ramanathan;Dadyburjor, Dady B.. And the article was included in Journal of Physical Chemistry in 1996.Reference of 112-59-4 The following contents are mentioned in the article:

The morphologies and phase volume fractions at which inversion occurred for (macro)emulsions formed by the middle-phase microemulsion (M) and water-rich bottom phase (B) were determined by means of elec. conductivity measurements for the amphiphile/oil/”water” system C₆H₁₃(OC₂H₄)₂OH/n-tetradecane/aqueous 10 mM NaCl at temperatures from 25 °C down to 12 °C, near the lower critical end-point temperature (T_lc =10.4 °C). The M/B and B/M morphologies and their inversion hysteresis lines conformed to the previously postulated dispersion morphol. diagram; i.e., within exptl. uncertainties, the two emulsion inversion lines in phase, volume-temperature space met at a “critical point” that coincided with the lower critical end point for the phases.

Bulky perneopentyloxy-pillar[5]arene (Pillar-1) I was synthesized and its conformational mobility was investigated using variable-temperature ¹H NMR spectroscopy. The host-guest interactions between Pillar-1 I and n-octyltrimethylammonium hexafluorophosphate (OMA) were investigated, and the formation of a 1 : 1 complex was revealed via¹H NMR. Planar-chiral isomers R/S II were synthesized via the reaction of a hydroxy-functionalized pillar[5]arene with chiral derivatization agent (2S)-3,3,3-trifluoro-2-methoxy-2-phenylpropanoyl chloride. The (Sp, R)-and (Rp, R)-forms of the pillar[5]arene diastereomers R/S II were isolated by HPLC, and their structures were analyzed by ¹⁹F NMR. HPLC measurements indicated that racemization did not take place at 40 °C for 72 h.
