《Ni-Catalyzed reductive amination of phenols with ammonia or amines into cyclohexylamines》 was written by Cuypers, Thomas; Morias, Thomas; Windels, Simon; Marquez, Carlos; Van Goethem, Cedric; Vankelecom, Ivo; De Vos, Dirk E.. Computed Properties of C7H8O2 And the article was included in Green Chemistry in 2020. The article conveys some information:

Phenol and its derivatives, which naturally occur in lignocellulose, can be considered as a renewable feedstock not only for aromatic, but also for alicyclic compounds, such as primary and N-substituted cyclohexylamines. So far, the latter are mostly produced from non-renewable starting materials like benzene via problematic nitration/reduction or cross-coupling routes. Herein, an efficient reductive amination of phenol with ammonia or amines is demonstrated, for the first time without the need for rare and expensive noble metals and without using any additives. Various supported Ni catalysts were screened and we elucidated the influence of the key parameters, including the acid-base properties of the supporting material. Acquired knowledge was then applied to different phenol-ammonia/amine combinations, resulting in the synthesis of various primary, secondary and tertiary cyclohexylamines in fair to very high yields. In addition to this study using m-Methoxyphenol, there are many other studies that have used m-Methoxyphenol(cas: 150-19-6Computed Properties of C7H8O2) was used in this study.

m-Methoxyphenol(cas: 150-19-6) may be used as an analytical standard for the determination of the analyte in wine, coffee beans, wood samples, and mainstream smoke by gas chromatography (GC) based techniques.Computed Properties of C7H8O2

《Development and Evaluation of Topical Delivery of Microemulsions Containing Adapalene (MEs-Ap) for Acne》 was written by Shao, Bing; Sun, Lixin; Xu, Na; Gu, Hongwei; Ji, Hongyu; Wu, Linhua. Synthetic Route of C28H28O3 And the article was included in AAPS PharmSciTech in 2021. The article conveys some information:

The main objective of the study was to prepare the microemulsions containing adapalene (MEs-Ap) to enhance epidermal penetration, dermal retention, and local bioavailability compared with the com. preparation The optimal formulations were selected by solubility experiments, pseudo-ternary phase diagram, and percutaneous permeation experiments and the physiochem. properties were also investigated. Then, the study of permeability, retention, safety, pharmacodynamics, and pharmacokinetics in the skin for MEs-Ap compared with the com. preparation were researched. The optimized formulation was developed as follows: the ratio of AP, iso-Pr myristate, polyoxyethylene hydrogenated castor oil, ethanol, and water was 0.01:1:1.25:3.75:4 (weight/weight). The globule size and average viscosity of the optimized MEs-Ap were 99.34 nm and 1.7 mPa·s, resp., which was oil-in-water microemulsion without serious irritation or allergy for skin. The Js, Qn, and Qretention of MEs-Ap (0.81 ± 0.19μg/cm2/h, 24.73 ± 4.24μg/cm2, 2.08 ± 0.18μg/cm2) were apparently higher than Differin (0.022 ± 0.009μg/cm2/h, 0.536 ± 0.103μg/cm2, and 0.523 ± 0.130μg/cm2) resp. The local bioavailability study showed that the AUC0 → 36h of the MEs-Ap in the dermal (19.6 ± 1.22μg/cm2) was significantly improved comparing to Differin (13.9 ± 1.73μg/cm2) (p < 0.01). The pharmacodynamics study showed that the therapeutic effect of MEs-Ap was better than that of Differin in the acne model of rabbit auricle. These results suggested that the MEs-Ap could be considered as a having higher epidermal penetrability, dermal retention, local bioavailability, efficacy, and safety topical preparations for acne. The experimental part of the paper was very detailed, including the reaction process of 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid(cas: 106685-40-9Synthetic Route of C28H28O3)

The article was titled 《Low-Cost Dopant Additive-Free Hole-Transporting Material for a Robust Perovskite Solar Cell with Efficiency Exceeding 21%》.Related Products of 101-70-2 The article contains the following contents:

Developing hole-transporting materials (HTMs) with appropriate mol. configuration and charge mobility is important to improve perovskite solar cell (PSC) photovoltaic performance and their feasibility for commercialization. In this work, a novel pyramidal-shaped low-cost HTM coded MeOTTVT is prepared through extension of π-conjugation based on a triphenylamine core. Carbon-carbon double bonds are introduced between the core and p-methoxyl triphenylamine to improve the planarity of the HTM, favoring intermol. stacking of MeOTTVT and thus improving the hole mobility of the corresponding hole-transporting layer (HTL). The p-methoxyl triphenylamine-endowed HTM benefits from a HOMO level well-aligned with the perovskite active layer, facilitating effective hole extraction The champion PSC using an MeOTTVT-based dopant additive-free HTL yielded a power conversion efficiency (PCE) up to 21.30%, which is considered one of the best-performing PSCs employing a dopant additive-free small mol.

Dong, Yubao; Zhu, Li; Yin, Bing; Zhu, Xinrui; Li, Dongfeng published their research in Dalton Transactions in 2021. The article was titled 《Regulating the magnetic properties of seven-coordinated Dy(III) single-ion magnets through the effect of positional isomers on axial crystal-field》.Category: ethers-buliding-blocks The article contains the following contents:

Six Dy(III) single-ion magnets (SIMs) [Dy(n-OMe-bbpen)X] were synthesized by a solvothermal reaction with three positional isomers (ortho, meta, and para) of ligands n-OMe-H2bbpen and dysprosium halides DyX3, (n-OMe-H2bbpen = N,N′-bis(2-hydroxy-n-methoxybenzyl)-N,N′-bis(2-methylpyridyl)ethylenediamine; n = 3, X = Cl, 1; n = 3, X = Br, 2; n = 4, X = Cl, 3; n = 4, X = Br, 4; n = 5, X = Cl, 5; n = 5, X = Br, 6). Dynamic magnetic measurements revealed that the six complexes possess notably different effective barriers of magnetic reversal: 872.0 K (1), 1210.1 K (2), 137.9 K (3), 602.6 K (4), 907.0 K (5) and 1216.7 K (6). 6 showed the best performance as SIMs among the six Dy(III) complexes. Moreover, the magnetic hysteresis loops of 6 remained open at 21 K. The crystal structures indicate the switching of local symmetry around Dy(III) ion, aroused by the variation in intermol. interactions and steric effects. This switch is primarily correlated with the distinction of magnetic properties. In addition, ab initio calculations confirmed that the different electrostatic potential around Dy(III) ion stemming from the electronic effect of the OMe-substituted group is another factor leading to the distinction in magnetic properties. This work warns us that when designing ligands for Dy-SIMs, the effect of positional isomerism on magnetic performance must be considered, which is one of the factors that can easily be overlooked.2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Category: ethers-buliding-blocks) was used in this study.
