Name: Methyl 2-chloro-2-oxoacetateIn 2019 ,《Ni-Catalyzed Reductive C-O Bond Arylation of Oxalates Derived from α-Hydroxy Esters with Aryl Halides》 was published in Organic Letters. The article was written by Gao, Mengyu; Sun, Deli; Gong, Hegui. The article contains the following contents:

A Ni-catalyzed reductive cross-coupling of α-hydroxycarbonyl compounds modified with oxalyl groups and aryl halides has been developed that furnishes α-aryl esters under mild conditions and tolerates a variety of functionalized aryl halides bearing electron-withdrawing and -donating groups. This work highlights C-O bond fragmentation on secondary alkyl carbon centers that generates α-carbonyl radicals.Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Name: Methyl 2-chloro-2-oxoacetate) was used in this study.

Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Name: Methyl 2-chloro-2-oxoacetate

Computed Properties of ClNaIn 2019 ,《Thin film nanocomposite hollow fiber membranes comprising Na+-functionalized carbon quantum dots for brackish water desalination》 was published in Water Research. The article was written by Gai, Wenxiao; Zhao, Die Ling; Chung, Tai-Shung. The article contains the following contents:

We have incorporated Na+-functionalized carbon quantum dots (Na-CQDs) into the polyamide layer via interfacial polymerization reaction and developed novel thin film nanocomposite (TFN) hollow fiber membranes for brackish water desalination. Comparing with the conventional thin film composite (TFC) membranes, the TFN membranes comprising Na-CQDs have a larger effective surface area, thinner polyamide layer and more hydrophilic oxygen-containing groups in the polyamide layer. Besides, the interstitial space among the polyamide chains becomes larger due to the presence of Na-CQDs. As a result, the incorporation of 1 wt% Na-CQDs into the polyamide layer could improve the pure water permeability (PWP) of the membranes from 1.74 LMH/bar to 2.56 LMH/bar by 47.1% without compromising their NaCl rejection of 97.7%. Interestingly, stabilization of the TFN hollow fiber membranes containing 1 wt% Na-CQDs at 23 bar could further promote the PWP to 4.27 LMH/bar and the salt rejection to 98.6% under the same testing conditions due to the deformation of the membranes under a high hydraulic pressure. When using a 2000 ppm NaCl aqueous solution as the feed, the optimal water flux and rejection of the newly developed TFN membranes at 15 bar are 57.65 ± 3.26 LMH and 98.6% ± 0.35% resp. The Na-CQDs incorporated TFN hollow fiber membranes show promising applications in the field of brackish water desalination. The experimental process involved the reaction of Sodium chloride(cas: 7647-14-5Computed Properties of ClNa)

Sodium chloride(cas: 7647-14-5) has been used for the preparation of tris buffered saline, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation wash buffer, LB (Luria-Bertani) media and dialysis buffer.Computed Properties of ClNa

Category: chlorides-buliding-blocksIn 2020 ,《Novel Sulfonanilide Inhibitors of SHIP2 Enhance Glucose Uptake into Cultured Myotubes》 was published in ACS Omega. The article was written by Berg, Mika E. A.; Naams, Jette-Britt; Hautala, Laura C.; Tolvanen, Tuomas A.; Ahonen, Jari P.; Lehtonen, Sanna; Wahala, Kristiina. The article contains the following contents:

A series of substituted sulfonanilide analogs were prepared and evaluated as novel potent inhibitors of SH2 domain-containing inositol polyphosphate 5′-phosphatase 2 (SHIP2). SHIP2 has been shown to be a new attractive target for the treatment of insulin resistance in type 2 diabetes mellitus (T2D), which can lead to life-threatening diabetic kidney disease (DKD). Amongst the synthesized compounds, the two most promising candidates, 10 and 11, inhibited SHIP2 significantly. Addnl., these compounds induced Akt activation in a dose-dependent manner, increased the presence of glucose transporter 4 at the plasma membrane, and enhanced glucose uptake in cultured myotubes in vitro at lower concentrations than metformin, the most widely used antidiabetic drug. These results show that the novel SHIP2 inhibitors have insulin sensitizing capacity and provide prototypes for further drug development for T2D and DKD. In addition to this study using Thiophene-2-sulfonyl chloride, there are many other studies that have used Thiophene-2-sulfonyl chloride(cas: 16629-19-9Category: chlorides-buliding-blocks) was used in this study.

Electric Literature of ClNaIn 2020 ,《Osmotic adjustment and energy limitations to plant growth in saline soil》 appeared in New Phytologist. The author of the article were Munns, Rana; Passioura, John B.; Colmer, Timothy D.; Byrt, Caitlin S.. The article conveys some information:

A review. Summary : Plant roots must exclude almost all of the Na+ and Cl- in saline soil while taking up water, otherwise these ions would build up to high concentrations in leaves. Plants evaporate c. 50 times more water than they retain, so 98% exclusion would result in shoot NaCl concentrations equal to that of the external medium. Taking up just 2% of the NaCl allows a plant to osmotically adjust the Na+ and Cl- in vacuoles, while organic solutes provide the balancing osmotic pressure in the cytoplasm. We quantify the costs of this exclusion by roots, the regulation of Na+ and Cl- transport through the plant, and the costs of osmotic adjustment with organic solutes in roots. In addition to this study using Sodium chloride, there are many other studies that have used Sodium chloride(cas: 7647-14-5Electric Literature of ClNa) was used in this study.

Application In Synthesis of 1-(Bromomethyl)-4-chlorobenzeneIn 2019 ,《Design, synthesis, biological evaluation, and molecular modeling studies of quinoline-ferulic acid hybrids as cholinesterase inhibitors》 appeared in Bioorganic Chemistry. The author of the article were Mo, Jun; Yang, Hongyu; Chen, Tingkai; Li, Qihang; Lin, Hongzhi; Feng, Feng; Liu, Wenyuan; Qu, Wei; Guo, Qinglong; Chi, Heng; Chen, Yao; Sun, Haopeng. The article conveys some information:

A series of quinoline-ferulic acid hybrids I (R = 1-chloro-4-(2-methoxyphenoxymethyl)benzene, 3-cyanophenyl, 4-(benzyloxy)-3-methoxyphenyl, etc.; R1 = H, Me; n = 1, 2, 3) has been designed, synthesized, and evaluated as cholinesterase inhibitors. Most of the compounds showed good inhibitory activities toward both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Among them, I (R = 1-bromo-4-(2-methoxyphenoxymethyl)benzene; R1 = Me; n = 1 (A)) was found to be the most potent inhibitor against AChE (IC50 = 0.62 ± 0.17 μM), and I (R = phenyl; R1 = Me; n = 3) was the most potent inhibitor against BChE (IC50 = 0.10 ± 0.01 μM). Representative compounds, such as (A) and I (R = 4-(trifluoromethyl)phenyl; R1 = Me; n = 1 (B)), act in a competitive manner when they inhibit AChE or BChE. Mol. docking and dynamic simulation revealed that the synthesized compounds bind to the target by simultaneously interacting with the catalytic active site (CAS) and the peripheral anionic site (PAS) of both AChE and BChE. The U-shaped confirmation was preferred when (B) bound to BChE, which was different from the linear conformation of (A) bound to AChE. Cell-based assays have confirmed the moderate neuroprotective effects of compounds (A) and (B) against H2O2-induced oxidative damage towards PC12 cells. Moreover, the hepatotoxicity of (B) was lower than that of tacrine, indicating its potential safety as an anti-Alzheimer’s agent. In summary, a new chemotype of multifunctional hybrid, which may be further modified to develop new anti-Alzheimer’s agents was reported. The experimental part of the paper was very detailed, including the reaction process of 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Application In Synthesis of 1-(Bromomethyl)-4-chlorobenzene)

Computed Properties of C6H6BFO2In 2019 ,《Efficient Access to 3, 4-Diarylpyrroles through Selective Bromination and Subsequent Suzuki-Coupling Reaction》 appeared in ChemistrySelect. The author of the article were Liu, Jianhui; Yu, Yaqiang. The article conveys some information:

An efficient and practical synthesis of 3, 4-disubstituted pyrrole was developed through bromination and the subsequent Suzuki-coupling reaction. The bromination of pyrrole-1-dimethylsulfonamide occurred selectively on the two β-positions to afford 3,4-dibromo-N,N-dimethyl-1H-pyrrole-1-sulfonamide, from which sym. and unsym. 3,4-diarylpyrroles were prepared through a stepwise Suzuki-coupling reaction. This reaction was complementary to the existing methods and was well-tolerable by a variety of functional groups. The bromination was scaled-up to gram-scale synthesis without decreasing the yield. In addition, the other halogenations of pyrrole were also studied and different chloro-products were isolated.

In 2022,Wu, Ying-Ai; Wang, Rui-An; Jiang, Shu-Yun; Jiang, Tai-Bai; Song, Jun-Rong; Shi, Jun; Wu, Wei; Pan, Wei-Dong; Ren, Hai published an article in Green Chemistry. The title of the article was 《Water enables the tunable electrochemical synthesis of heterocyclic 3a- or 5a-bromoindolines》.Category: chlorides-buliding-blocks The author mentioned the following in the article:

Due to the electron-richness of the C3/C2 positions of the indole moiety, direct nucleophilic bromination at the C5-position of tryptophol and tryptamine derivatives is difficult and remains unexplored. Herein, authors report a tunable water-mediated electrooxidative protocol for the dearomative C3/C5-bromocyclization of tryptophol and tryptamine derivatives This electrosynthetic approach enables selective construction of cyclic 3a- or 5a-bromoindolines simply by the addition of different amounts of water, with no addnl. electrolytes, external oxidants, or additives being required. Less water delivers the cyclic 3a-bromoindoline, while more water delivers the 5a-bromoindoline. A detailed mechanistic study showed that an unexpected collaborative bromide ionic electrooxidation at the anode and reductive hydrodebromination at the cathode in the presence of more water is key to the tunable chemoselectivity control. In the experiment, the researchers used Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Category: chlorides-buliding-blocks)

Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Category: chlorides-buliding-blocks
