《Amino-Acid-Mediated Aerobic Oxidation of Organoborons for the Synthesis of Phenolic Derivatives Using Single Electron Transfer》 was published in ChemistrySelect in 2020. These research results belong to Gujjarappa, Raghuram; Vodnala, Nagaraju; Garg, Aakriti; Hazra, Chinmoy K.; Gupta, Sreya; Malakar, Chandi C.. Computed Properties of C6H7BO3 The article mentions the following:

An efficient amino-acid-mediated ipso-hydroxylation of arylboronic acids, aryl boronate esters and aryl trifluoroborates RX (R = 4-chlorophenyl, naphthalen-1-yl, quinolin-5-yl, etc.; X = BF3K, B(OH)2, Bpin) to aryl alcs. ROH has been described. The current protocol was realized by using sub-stoichiometric amount of L-histidine in presence of triethylamine under aerobic conditions in DMF as solvent. This amino-acid-mediated process provides an alternative route for the hydroxylation of organoborons through in situ generation of hydrogen peroxide. The present protocol explores the synthetic utility of amino acids as organocatalysts for the preparation of aryl alcs. It was observed that L-histidine plays an important role for the conversion of aerial oxygen into hydrogen peroxide via thermal excitation process followed by thermal degradation of Et3N. The developed approach holds good for a wide range of compounds with excellent yields and competent functional group tolerance. The experimental process involved the reaction of 2-Hydroxyphenylboronic acid(cas: 89466-08-0Computed Properties of C6H7BO3)

Du, Xin; Zhao, Huan; Li, Xinling; Zhang, Lizhi; Dong, Yunhui; Wang, Ping; Zhang, Daopeng; Liu, Qing; Liu, Hui published an article in 2021. The article was titled 《Ligand-Regulated Palladium-Catalyzed Regiodivergent Hydroarylation of the Distal Double Bond of Allenamides with Aryl Boronic Acid》, and you may find the article in Journal of Organic Chemistry.Related Products of 89466-08-0 The information in the text is summarized as follows:

The ligand-regulated regiodivergent hydroarylation of the distal double bond of allenamides with aryl boronic acid was achieved in the presence of Pd(II) catalysts, delivering a variety of functionalized enamide with excellent E selectivity and Markovnikov/anti-Markovnikov selectivity. Two possible coordination intermediates probably are responsible for the regiodivergent hydroarylation: (1) The coordination Intermediate I, which probably is formed through the coordination of MeCN, distal double bond, Ph to Pd, led to the aryl group away from the Intermediate I, inducing excellent E selectivity and anti-Markovnikov selectivity. (2) A switch of regioselectivity to 1,2-Markovnikov hydroarylation was obtained using bidentate phosphine ligand (dppf or Xantphos). The formed coordination Intermediate II led to the N-tether away from the Intermediate II and at the trans position of aryl, resulting in excellent E selectivity and Markovnikov selectivity. Meanwhile, tentative study on the mechanism proved that the hydron source of this hydroarylation is more likely to be boronic acid. The transmetalation between aryl boronic acid and Pd catalyst was the initial step of this transformation.

《Thermogravimetric analysis of aromatic boronic acids for potential flame retardant applications》 was published in Thermochimica Acta in 2020. These research results belong to Cromwell, Benjamin; Levenson, Adelaide; Levine, Mindy. HPLC of Formula: 89466-08-0 The article mentions the following:

The need for non-halogenated flame retardants continues to increase as more information about the toxicity of halogenated flame retardants and their pyrolytic byproducts becomes available. One class of non-halogenated flame retardants, organic boronic acids, has been reported in a number of papers as having flame retardant effects for cellulosic fibers as well as synthetic polymers. To improve this performance, an understanding of how the structure of the boronic acid affects its flame-retardant properties as well as its thermal stability is necessary. Reported herein are experiments aimed at achieving precisely this understanding, by investigating the thermal stability and degradation pathways of a broad variety of boronic acids, and using the resulting data to develop rules about the relationship between boronic acid structure (number of boronic acid moieties; presence/absence of functional groups, etc.) and the compound’s thermal stability. These experiments highlight a number of boronic acids with exceptional thermal stability, with pyrene-1-boronic acid (compound 18) in particular showing stability up to 600°C. In the experiment, the researchers used many compounds, for example, 2-Hydroxyphenylboronic acid(cas: 89466-08-0HPLC of Formula: 89466-08-0)

In 2019,ACS Chemical Neuroscience included an article by Jorg, Manuela; van der Westhuizen, Emma T.; Khajehali, Elham; Burger, Wessel A. C.; White, Jonathan M.; Choy, Kwok H. C.; Tobin, Andrew B.; Sexton, Patrick M.; Valant, Celine; Capuano, Ben; Christopoulos, Arthur; Scammells, Peter J.. SDS of cas: 89466-08-0. The article was titled 《6-phenylpyrimidin-4-ones as positive allosteric modulators at the M1 mAChR: the determinants of allosteric activity》. The information in the text is summarized as follows:

Targeting allosteric sites of the M1 muscarinic acetylcholine receptor (mAChR) is an enticing approach to overcome the lack of receptor subtype selectivity observed with orthosteric ligands. This is a promising strategy for obtaining novel therapeutics to treat cognitive deficits observed in Alzheimer’s disease and schizophrenia, while reducing the peripheral side effects such as seen in the current treatment regimes, which are non-subtype selective. We previously described compound I, the first pos. allosteric modulator (PAM) of the M1 mAChR based on a 6-phenylpyrimidin-4-one scaffold, which has been further developed in this study. Herein, we present the synthesis, characterization, and pharmacol. evaluation of a series of 6-phenylpyrimidin-4-ones with modifications to the 4-(1-methylpyrazol-4-yl)benzyl pendant. Selected compounds were further profiled in terms of their allosteric affinity, cooperativity with acetylcholine (ACh), and intrinsic efficacy. Addnl., I and II were tested in mouse primary cortical neurons, displaying various degrees of intrinsic agonism and potentiation of the acetylcholine response. Overall, the results suggest that the pendant moiety is important for allosteric binding affinity and the direct agonistic efficacy of the 6-phenylpyrimidin-4-one based M1 mAChR PAMs. In the experimental materials used by the author, we found 2-Hydroxyphenylboronic acid(cas: 89466-08-0SDS of cas: 89466-08-0)

In 2022,Luo, Xu-Feng; Ni, Hua-Xiu; Ma, Hui-Li; Qu, Zhong-Ze; Wang, Jie; Zheng, You-Xuan; Zuo, Jing-Lin published an article in Advanced Optical Materials. The title of the article was 《Fused π-Extended Multiple-Resonance Induced Thermally Activated Delayed Fluorescence Materials for High-Efficiency and Narrowband OLEDs with Low Efficiency Roll-Off》.Computed Properties of C6H7BO3 The author mentioned the following in the article:

The simultaneous achievement of multiple-resonance thermally activated delayed fluorescence (MR-TADF) materials with strong narrowband emission and efficient reverse intersystem crossing (RISC) process can further promote the advancement of organic light-emitting diodes (OLEDs). Herein, a new strategy is proposed to achieve two π-extended MR-TADF emitters (NBO and NBNP) peaking at 487 and 500 nm via fusing conjugated high-triplet-energy units (carbazole, dibenzofuran) into boron-nitrogen (B/N) framework, aiming to increase charge transfer delocalization of the B/N skeleton and minimize singlet-triplet energy gap (ΔEST). This strategy endows the two emitters with full width at half maximum of 27 and 29 nm, and high photoluminescence efficiencies above 90% in doped films, resp. Addnl., considerable rate constants of RISC are obtained due to the small ΔEST (0.12 and 0.09 eV) and large spin-orbital coupling values. Consequently, the OLEDs based on NBO and NBNP show the maximum external electroluminescence quantum efficiency of up to 26.1% and 28.0%, resp., accompanied by low-efficiency roll-off. These results provide a feasible design strategy to construct efficient MR-TADF materials for OLEDs with suppressed efficiency roll-off.

The article conveys some information:

In this communication, the first time a one-pot synthesis of the xanthone scaffold based on a carbonylative Suzuki coupling was reported. Iodophenol and (2-methoxyphenyl)boronic acid were coupled under carbon monoxide, generated from a carbon monoxide surrogate. An exptl. data-based model was built to guide the reaction optimization. The optimized conditions were 1 mol% of a pincer complex as palladium catalyst, 5 equiv of K2CO3 as base, and DMF:water (7 : 3) as solvent. The robustness of the synthetic method, namely in terms of the reactants scope, was also evaluated. This approach provided the xanthone scaffold in high yields and provided a deep insight into the carbonylative Suzuki couplings.
