The author of 《NMR Quantification of Hydrogen-Bond-Activating Effects for Organocatalysts including Boronic Acids》 were Diemoz, Kayla M.; Franz, Annaliese K.. And the article was published in Journal of Organic Chemistry in 2019. Formula: C6H6BFO2 The author mentioned the following in the article:

The hydrogen-bonding activation for 66 organocatalysts has been quantified using a 31P NMR binding experiment with triethylphosphine oxide (TEPO). Diverse structural classes, including phenols, diols, silanols, carboxylic acids, boronic acids, and phosphoric acids, were examined with a variety of steric and electronic modifications to understand how the structure and secondary effects contribute to hydrogen-bonding ability and catalysis. Hammett plots demonstrate high correlation for the Δδ 31P NMR shift to Hammett parameters, establishing the ability of TEPO binding to predict electronic trends. Upon correlation to catalytic activity in a Friedel-Crafts addition reaction, data demonstrate that 31P NMR shifts correlate to catalytic activity better than pKa values. Boronic acids were investigated, and 31P NMR binding experiments predicted strong hydrogen-bonding ability, for which catalytic activity was confirmed, resulting in the greatest rate enhancement observed in the Friedel-Crafts addition of all organocatalysts studied. A detailed investigation supports that boronic acid activation proceeds through hydrogen-bonding interactions and not coordination with the Lewis acidic boron center. Using 31P NMR spectroscopy offers a simple and rapid tool to quantify and predict hydrogen-bonding abilities for the design and applications of new organocatalysts and supramol. synthons. In the experiment, the researchers used many compounds, for example, (3-Fluorophenyl)boronic acid(cas: 768-35-4Formula: C6H6BFO2)

(3-Fluorophenyl)boronic acid(cas: 768-35-4) can be used to make novel liquid crystalline fluorobiphenylcyclohexenes and difluoroterphenyls by palladium-catalyzed cross-couplings also used in the synthesis of o-phenylphenols as potent leukotriene B4 receptor agonists.Formula: C6H6BFO2

A method for the preparation of chiral triarylmethanes via organocatalytic 1,6-addition of arylboronic acids to para-quinone methides (p-QMs) was established. Here the use of salicylaldehyde-derived p-QMs with an ortho-hydroxy substituent as a directing group was essential for the remote stereocontrol. In the presence of a BINOL catalyst, chiral triarylmethanes, e.g., I, can be obtained in high yields (up to 99%) with excellent enantioselectivities (up to 99% ee). This method shows broad substrate tolerance and can be easily scaled up, both electron-rich and electron-deficient arylboronic acids are suitable substrates for this addition reaction.

The article was titled 《Synthesis and Screening in Mice of Fluorine-Containing PET Radioligands for TSPO: Discovery of a Promising 18F-Labeled Ligand》, and you may find the article in Journal of Medicinal Chemistry.HPLC of Formula: 768-35-4 The information in the text is summarized as follows:

Translocator protein 18 kDa (TSPO) is a biomarker of neuroinflammation. [11C]ER176 robustly quantifies TSPO in the human brain with positron emission tomog. (PET), irresp. of subject genotype. We aimed to develop an ER176 analog with potential for labeling with longer-lived fluorine-18 (t1/2 = 109.8 min). New fluoro and trifluoromethyl analogs of ER176 were prepared through a concise synthetic strategy. These ligands showed high TSPO affinity and low human genotype sensitivity. Each ligand was initially labeled by a generic 11C-methylation procedure, thereby enabling speedy screening in mice. Each radioligand was rapidly taken up and well retained in the mouse brain at baseline after i.v. injection. Preblocking of TSPO showed that high proportions of brain uptake were specifically bound to TSPO at baseline. Overall, the 3-fluoro analog of [11C]ER176 ([11C]3b) displayed the most promising imaging properties. Therefore, a method was developed to label 3b with [18F]fluoride ion. [18F]3b gave similarly promising PET imaging results and deserves evaluation in higher species. The results came from multiple reactions, including the reaction of (3-Fluorophenyl)boronic acid(cas: 768-35-4HPLC of Formula: 768-35-4)

The article was titled 《Iridium-catalyzed Z-retentive asymmetric allylic substitution reactions》, and you may find the article in Science (Washington, DC, United States).Recommanded Product: 768-35-4 The information in the text is summarized as follows:

Z-Olefins are challenging synthetic targets owing to their relative thermodn. instability. Transition metal-catalyzed asym. allylic substitution reactions are well known for installing stereocenters adjacent to branched or E-linear olefins. However, analogous reactions for the synthesis of optically active Z-olefin products are rare. Here we report iridium-catalyzed asym. allylic substitution reactions that retain Z-olefin geometries while establishing an adjacent quaternary stereocenter. The formation of transient anti-π-allyl-iridium intermediates and their capture by external nucleophiles before isomerization to the thermodynamically more stable syn-π-allyl-iridium counterparts have been observed These results provide a promising method for preparing chiral Z-olefinic compounds In addition to this study using (3-Fluorophenyl)boronic acid, there are many other studies that have used (3-Fluorophenyl)boronic acid(cas: 768-35-4Recommanded Product: 768-35-4) was used in this study.

《Ligand-Controlled Regiodivergence in Nickel-Catalyzed Hydroarylation and Hydroalkenylation of Alkenyl Carboxylic Acids》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Li, Zi-Qi; Fu, Yue; Deng, Ruohan; Tran, Van T.; Gao, Yang; Liu, Peng; Engle, Keary M.. Synthetic Route of C6H6BFO2 The article mentions the following:

A nickel-catalyzed regiodivergent hydroarylation and hydroalkenylation of unactivated alkenyl carboxylic acids is reported, whereby the ligand environment around the metal center dictates the regiochem. outcome. Markovnikov hydrofunctionalization products were obtained under mild ligand-free conditions, with up to 99% yield and >20:1 selectivity. Alternatively, anti-Markovnikov products can be accessed with a novel 4,4-disubstituted Pyrox ligand in excellent yield and >20:1 selectivity. Both electronic and steric effects on the ligand contribute to the high yield and selectivity. Mechanistic studies suggest a change in the turnover-limiting and selectivity-determining step induced by the optimal ligand. DFT calculations reveal that in the anti-Markovnikov pathway, repulsion between the ligand and the alkyl group is minimized (by virtue of it being 1° vs. 2°) in the rate- and regioselectivity-determining transmetalation transition state.
