The synthesis, liquid crystalline properties and dielec. properties of a new bent-core compound (DBOB) composed of terephthalate based rod-like units with a O-dodecyl lactate group substituted at one side as well as n-octyloxy located at other terminal are presented. The liquid crystalline properties have been investigated by polarizing optical microscopy, differential scanning calorimetry and electro-optical studies. The dielec. parameters and phase regions of DBOB, which exhibits an enantiotropic non-polar SmA phase between 156 and 100° as well as SmA phase with a ferroelec. polar response at lower temperatures than 100°, have been carried out by impedance spectroscopy at different temperatures The dielec. relaxation mechanisms have been analyzed by Cole-Cole plots. The Debye distribution parameters and activation energies have also been determined This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Electric Literature of C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.Electric Literature of C13H12O2

Fluoroalkylation of Various Nucleophiles with Fluoroalkyl Sulfones through a Single Electron Transfer Process was written by Xiao, Pan;Ni, Chuanfa;Miao, Wenjun;Zhou, Min;Hu, Jingyu;Chen, Dingben;Hu, Jinbo. And the article was included in Journal of Organic Chemistry in 2019.Reference of 103-16-2 The following contents are mentioned in the article:

The fluoroalkylation of various nucleophilic reagents with (phenylsulfonyl)difluoromethyl (PhSO₂CF₂)-substituted phenanthridines was achieved to give fluorinated phenanthridine derivatives, which enables the construction of both carbon-heteroatom and carbon-carbon bonds via the substitution of the phenylsulfonyl group. Mechanistic studies indicated that these reactions proceed through a unimol. radical nucleophilic substitution (S_RN1) mechanism. It is worthwhile noting that in the cases of O-nucleophiles (t-BuO^– and PhO^–), the addition of t-BuOK/PhCHO could significantly promote the reactions, due to the in situ formation of a highly reactive electron donor species through the interaction of t-BuOK, PhCHO, and the solvent DMF, which can effectively initiate the single electron transfer process. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Reference of 103-16-2).

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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Reference of 103-16-2

And the article was included in ACS Macro Letters in 2019.Formula: C13H12O2 The following contents are mentioned in the article:

Here we report columnar liquid-crystalline (LC) nanostructured membranes that highly remove viruses and show sufficient water permeation. These membranes were prepared by employing two-component liquid crystals that exhibit tetragonal columnar phases. The membranes exhibited virus rejection values of >99.99% (log₁₀ reduction value (LRV) > 4) and water flux ranging from 19 to 61 L m^-2 h^-1 (operation pressure: 0.3 MPa). These membranes were fabricated by photopolymerization of a fan-shaped diol mol. and imidazolium ionic liquid mixture, followed by subsequent removal of the ionic liquid The rejection values and water flux depend on the fraction of ionic liquid These results show new design strategies of materials for the water treatment nanostructured membranes that remove pathogens and contaminants. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Formula: 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

Intramolecular Oxidative Coupling between Unactivated Aliphatic C-H and Aryl C-H Bonds was written by Liao, Yang;Zhou, Yi;Zhang, Zhen;Fan, Junzhen;Liu, Feng;Shi, Zhangjie. And the article was included in Organic Letters in 2021.Name: 4-Benzyloxyphenol The following contents are mentioned in the article:

In this article, a Pd-catalyzed intramol. oxidative coupling between unactivated aliphatic and aryl C-H compounds ROCH₂C(CH₃)₂CO₂H (R = C₆H₅, 4-ClC₆H₄, 2-naphthyl, etc.) has been described. This chem. showed great potential to build up fused cyclic scaffolds I (R¹ = H, Me, OMe; R² = Me, Ph, F, etc.; R³ = H, Me; R⁴ = H, Me; R¹R² = R³R⁴ = -CH=CHCH=CH-) and 3-methyl-3,4-dihydro-2H-benzofuro[2,3-h]chromene-3-carboxylic acid from linear substrates through oxidative couplings. Privileged chromane and tetralin scaffolds were constructed from readily available linear starting materials in the absence of any organohalides and organometallic partners. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Name: 4-Benzyloxyphenol).

4-Benzyloxyphenol (cas: 103-16-2) 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.Name: 4-Benzyloxyphenol

And the article was included in Advanced Synthesis & Catalysis in 2014.Application In Synthesis of 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane The following contents are mentioned in the article:

A new, catalytic methodol. for the synthesis of heterobiaryls by the ruthenium-catalyzed C-H activation/cross-coupling of heterocyclic amides with 2-aryl-1,3,2-dioxaborinanes is surveyed. From this survey, the highly regioselective reaction of furan-3-carboxamide to give 2-aryl-3-furanamides is optimized and generalized in scope with respect to the 2-aryl-1,3,2-dioxaborinane partners. E.g., in presence of RuH₂(CO)(PPh₃)₃ in toluene, reaction of N,N-diethylfuran-3-carboxamide with 2-aryl-1,3,2-dioxaborinane derivative (I) gave 92% heterobiaryl (II). Established thereby is a one-step synthetic method which may supercede the broadly applied two-step directed ortho metalation (DoM)-cross coupling reaction involving cryogenic and strong base conditions and which has potential for further ortho and remote metalation chem.

Constructing chiral bicyclo[3.2.1]octanes via palladium-catalyzed asymmetric tandem Heck/carbonylation desymmetrization of cyclopentenes was written by Yuan, Zhenbo;Zeng, Yuye;Feng, Ziwen;Guan, Zhe;Lin, Aijun;Yao, Hequan. And the article was included in Nature Communications in 2020.Application of 103-16-2 The following contents are mentioned in the article:

A palladium-catalyzed asym. tandem Heck/carbonylation desymmetrization of cyclopentenes I (R = COMe, CO₂Et; R¹ = H, F, Cl, Me, OMe; X = I, Br) has been described. Alcs., (such as., n-propanol, isopropanol, cyclohexanol, etc.) phenols (such as., 4-methylphenol, biphenyl-4-ol, naphthol, etc.) and amines (such as., pyrrolidine, morpholine, benzylamine, etc.) are employed as versatile coupling reagents for the construction of multifunctional chiral bicyclo[3.2.1]octanes II (R² = OMe, OEt, OPh, pyrrolidino, morpholino, thiomorpholino, etc.) with one all-carbon quaternary and two tertiary carbon stereogenic centers in high diastereo- and enantioselectivities. This study represents an important progress in both the asym. tandem Heck/carbonylation reactions and enantioselective difunctionalization of internal alkenes. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Application of 103-16-2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
