An efficient electrophilic amidomethylation of aromatics was described to construct N-benzylic amides, which are core structures in drugs and natural products. The simple combination of DMSO (DMSO, as the CH2 unit) and acetonitrile (MeCN, as the nitrogen unit) as a highly active amidomethylation reagent enables the efficient C-C, C-N and C=O bond construction. Notably, this method provides a practical protocol for the efficient preparation of deuterated benzylamine derivatives with easily available d6-DMSO or d3-MeCN, and is also applied in the concise synthesis of Nonivamide and Pimavanserin. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Formula: C11H10O

On September 3, 2021, Palav, Amey; Misal, Balu; Chaturbhuj, Ganesh published an article.Electric Literature of 93-04-9 The title of the article was NCBSI/KI: A Reagent System for Iodination of Aromatics through In Situ Generation of I-Cl. And the article contained the following:

In-situ iodine monochloride (I-Cl) generation followed by iodination of aromatics using NCBSI/KI system was developed. The NCBSI reagent required no activation due to longer bond length, lower bond dissociation energy, and higher absolute charge d. on nitrogen. The system was adequate for mono- and diiodination of a wide range of moderate to highly activated arenes with good yield and purity. Moreover, the precursor N-(benzenesulfonyl)benzenesulfonamide was recovered and transformed to NCBSI and made the protocol eco-friendly and cost-effective.

Duesel, Simon Josef Siegfried; Koenig, Burkhard published an article in 2020, the title of the article was Oxidative Photochlorination of Electron-Rich Arenes via in situ Bromination.Recommanded Product: 2-Methoxynaphthalene And the article contains the following content:

Electron-rich arenes are oxidatively photochlorinated in the presence of catalytic amounts of bromide ions, visible light, and 4CzIPN as organic photoredox catalyst. The substrates are brominated in situ in a first photoredox-catalyzed oxidation step, followed by a photocatalyzed ipso-chlorination, yielding the target compounds in high ortho/para regioselectivity. Dioxygen serves as a green and convenient terminal oxidant. The use of aqueous hydrochloric acid as the chloride source reduces the amount of saline byproducts.

On July 1, 2022, Baker, Sarah I.; Yaghoubi, Mahshid; Bidwell, Samantha L.; Pierce, Savannah L.; Hratchian, Hrant P.; Baxter, Ryan D. published an article.Computed Properties of 93-04-9 The title of the article was Enhanced Reactivity for Aromatic Bromination via Halogen Bonding with Lactic Acid Derivatives. And the article contained the following:

Herein, a new method for regioselective aromatic bromination using lactic acid derivatives as halogen bond acceptors with N-bromosuccinimide (NBS) is reported. Several structural analogs of lactic acid affected the efficiency of aromatic brominations, presumably via Lewis acid/base halogen-bonding interactions. Rate comparisons of aromatic brominations demonstrated the reactivity enhancement available via catalytic additives capable of halogen bonding. Computational results demonstrated that Lewis basic additives interact with NBS to increase the electropos. character of bromine prior to electrophilic transfer. An optimized procedure using catalytic mandelic acid under aqueous conditions at room temperature has been developed to promote aromatic bromination on a variety of arene substrates with complete regioselectivity. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Computed Properties of 93-04-9

On February 8, 2022, Lui, Yuen Wai; Chan, Bun; Lui, Matthew Y. published an article.Application In Synthesis of 2-Methoxynaphthalene The title of the article was Methylation with Dimethyl Carbonate/Dimethyl Sulfide Mixtures: An Integrated Process without Addition of Acid/Base and Formation of Residual Salts. And the article contained the following:

Di-Me sulfide, a major byproduct of the Kraft pulping process, was used as an inexpensive and sustainable catalyst/co-reagent (Me donor) for various methylations with di-Me carbonate (as both reagent and solvent), which afforded excellent yields of O-methylated phenols and benzoic acids, and mono-C-methylated arylacetonitriles. Furthermore, these products could be isolated using a remarkably straightforward workup and purification procedure, realized by di-Me sulfide’s neutral and distillable nature and the absence of residual salts. The likely mechanisms of these methylations were elucidated using exptl. and theor. methods, which revealed that the key step involves the generation of a highly reactive trimethylsulfonium methylcarbonate intermediate. The phenol methylation process represents a rare example of a Williamson-type reaction that occurs without the addition of a Bronsted base.

A proof-of-concept study of hypervalent chalcogenonium…蟺 bonding catalysis was performed. A new catalytic strategy using 1,2-oxaselenolium salts as chalcogen bond donors and alkenes as chalcogen bond acceptors is described. The feasibility of this concept is demonstrated by the use of trisubstituted selenonium salts in the metal-free catalytic hydrofunctionalization and polymerization of alkenes via unconventional seleniranium ion-like intermediates. The results indicate that counter anions have a significant effect on the catalysis based on hypervalent chalcogenonium…蟺 bonding interactions.

On June 5, 2022, Yao, Juanjuan; Chen, Zihan; Zhang, Huiying; Gao, Naiyun; Zhang, Zhi; Jiang, Wenchao published an article.Application of 93-04-9 The title of the article was New insight into the regulation mechanism of visible light in naproxen degradation via activation of peroxymonosulfate by MOF derived BiFeO3. And the article contained the following:

BiFeO3 (BFO) nanocage prepared by metal-organic-framework derivatization (MOF-d) was adopted as activator to first investigate the effect mechanism of visible-light on naproxen-degradation via peroxymonosulfate (PMS) activation. MOF-d BFO expressed more excellent PMS activation ability than hydrothermal-synthetic BFO, due to highly ordered mesopores. A 3.0 times higher pseudo-first-order degradation rate constant was achieved after visible-light introduced. The quenching experiments indicated that the contribution of ROS in naproxen degradation followed the order of SO鈥?4>1O2 鈮?鈥H in MOF-d BFO/PMS/dark system, while changed into h+>1O2 > >O鈥?app2SO鈥?4> 鈥H after visible-light introduced. EPR tests first revealed that visible-light promoted 1O2 yield (non-radical pathway) but suppressed 鈥H and SO鈥?4 generation (free-radical pathways). N2-purging experiments further proved that 1O2 primarily originates from the reaction between h+ and PMS, equivalently to that between O2 and e–h+ in MOF-d BFO/PMS/vis system. Under visible-light, PMS activation via 顚咶e (III) might be hindered by e- filling on Fe 3d orbital and anion PMS preferred to approach h+ rather than e-, resulting in the decrease of 鈥H and SO鈥?4 yields. Moreover, PMS faces competition from adsorbed-O2 and oxygen-vacancies for e- capture. The degradation-pathways for naproxen in dark and under visible light were both proposed in MOF-d BFO/PMS system. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Application of 93-04-9

And the article contained the following:

For the urgent need for fermentation control and product quality improvement of Pu-erh tea, gas chromatog.-mass spectrometry and odor activity value (OAV) were used to comprehensively investigate the flavor-active compounds during artificial fermentation of Pu-erh tea. A flavor wheel was constructed to expound the sensory attributes evolution during fermentation With an increased total volatiles content, 43 were significantly up-regulated and 30 were down-regulated among 131 detected volatiles. Key active compounds of three aroma types, namely fresh fragrance, fruit-fungus fragrance and stale-Qu fragrance, were analyzed based on OAV. 尾-damascenone was firstly found contributing most to the aroma of Pu-erh tea, followed by 1,2,3-methoxybenzene and (E,E)-2,4-nonadienal. 纬-terpinene, linalool, 1,2,4-trimethoxybenzene, 1,2,3-trimethoxybenzene, and 4-ethylveratrol were identified as the potential markers responsible for aroma differences among three fermentation stages. Finally the metabolic evolution of key flavor-active compounds were systematically summarized. This study provides significant guidance in fermentation control and new product development of Pu-erh tea. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Electric Literature of 93-04-9
