The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5.

The borane-catalyzed synthesis of dihydroquinoline-4-ones is developed. The amino-substituted chalcones undergo a 1,7-hydride shift upon Lewis acid activation to form a zwitterionic iminium enolate, which collapses to the dihydroquinoline-4-one scaffold. The reaction proceeds in high yields (75-99%) with an excellent diastereoselectivity of up to >99:1 (cis:trans). The reaction mechanism is investigated by kinetic, isotope labeling, and computational experiments.

A cheap, facile and metal-free photochemical protocol for the activation of aromatic aldehydes has been developed. Utilizing thioxanthen-9-one as the photocatalyst and cheap household lamps as the light source, a variety of aromatic aldehydes have been activated and subsequently converted in a one-pot reaction into amides, hydroxamic acids and esters in good to high yields. The applicability of this method was highlighted in the synthesis of Moclobemide, a drug against depression and social anxiety. Extended and detailed mechanistic studies have been conducted, in order to determine a plausible mechanism for the reaction.

An article Electrometric bromine number as a suitable method for the quantitative determination of phenols and olefins in hydrotreated pyrolysis bio-oils WOS:000652032600064 published article about QUANTIFICATION; TITRATION in [Auersvald, Milos; Stas, Martin; Simacek, Pavel] Univ Chem & Technol, Dept Petr Technol & Alternat Fuels, Tech 5, Prague 16628 6, Czech Republic in 2021, Cited 29.

Bio-oils after hydrotreatment can still contain significant amount of phenols and cyclic olefins as the products of an incomplete deoxygenation. The removal of these compounds would be necessary to produce suitable components for automotive fuels. However, no routine method currently exists for the reliable determination of these groups in hydrotreated bio-oils (HBOs). In this paper, we analyzed 140 different pure oxygenates as model compounds using the bromine number method (ASTM D1159) observing that most compounds present in HBOs react with one equivalent of bromine. The determination of phenols using bromine number method in crude biooil is complicated especially by the presence of guaiacols and syringols that react with more than one equivalent of bromine and, thus, the obtained result is significantly overestimated. Further we optimized the chromatographic separation of hydrocarbons from HBOs for the selective determination of olefins content. As no other reactive compounds under the conditions of the method, besides phenols and olefins, were observed in HBOs, the difference between HBO bromine number (before hydrocarbons separation) and olefins content correspond to the total amount of phenols. The method was finally applied to 11 HBOs with different content of oxygen, providing a good correlation between phenols and oxygen content.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.

A regioselective radical C-H trifluoromethylation of aromatic compounds was developed using cyclodextrins (CDs) as additives. The C-H trifluoromethylation proceeded with high regioselectivity to afford the product in good yield, even on the gram scale. In the presence of CDs, some substrates underwent a single trifluoromethylation selectively, whereas mixtures of single- and double-trifluoromethylated products were formed in the absence of the CD. H-1 NMR experiments indicated that the regioselectivity was controlled by the inclusion of a substrate inside the CD cavity.

The novel metal-organic framework Co-2(bdda)(1.5)(OAc)(1)5H(2)O (UoB-3) was synthesized via a simple method at room temperature. UoB-3 was characterized by the different methods, including X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), N-2-adsorption/desorption and elemental analysis. The catalytic ability of UoB-3 was detected to be excellent for primary and secondary alcohols oxidation reaction with high yields under solvent-free conditions. Moreover, UoB-3 was highly active for Henry reaction of different aldehydes with nitromethane in water as a green solvent. The nanocatalyst can be recycled for five consecutive cycles without losing its activity and structural rigidity. The antibacterial activity of UoB-3 nanostructures towards Gram-negative bacteria, Escherichia coli and Gram-positive bacteria, Bacillus cereus was also evaluated by using an inhibition zone test. These nanostructures exhibited strong antibacterial effect against both of them. The purpose of this study was the developing metal-organic framework materials with the enhanced activity in various fields.

I found the field of Chemistry; Environmental Sciences & Ecology very interesting. Saw the article Development of a method based on thermal desorption-gas chromatography/mass spectrometry for the determination of 103 volatile organic compounds in mattresses published in 2020.0. Formula: C7H8O, Reprint Addresses Cao, SR (corresponding author), Southwest Univ Polit Sci & Law, Forens Identificat Ctr, Chongqing, Peoples R China.. The CAS is 100-51-6.

A sensitive and reliable method based on environment test chamber coupled with thermal desorption and gas chromatography-mass spectrometry (ETC-TD-GC/MS) was developed and validated for the determination of 103 volatile organic compounds (VOCs) emitted from mattresses. In the study, two commercial sorbent tubes were compared in terms of adsorption efficiency towards the target analytes. The result illustrated that the multisorbent tubes containing Carbopack C, Carbopack B and Carboxen 1000 had better performance than Tenax TA tubes owing to their large surface area, low capacity for water and high temperature stability, which allowed a wide range of VOCs to be absorbed, especially for VOCs with low boiling points and small molecules. To achieve the optimum conditions for the analysis, several thermal desportion parameters were accurately investigated. Under the optimal conditions, the method showed good linearities, with correlation coefficients ranging from 0.9982 to 0.9999 and the method detection limits and method quantification limitsfor target compounds in the range of 0.006 similar to 0.561 mu g/m(3) and 0.020 similar to 1.870 mu g/m(3), respectively. In order to evaluate the performance of the developed method on real samples, various mattresses from different manufacturers were analysed. All mattress samples were found to emit VOCs and the values of area-specific emission rate (SERs) for total target compounds were in the range of 90.25 similar to 288.63 mu g/m(2)center dot h. Moreover, the SERs of VOCs were influenced by the type of sponge materials and mattress fabric layers. The study demonstrated that the method is sensitive, accurate and well-suited for the determination of VOCs emitted from mattresses.
