N-Alkyl/aryl amines RNHCH2R1 [R = C6H5, t-BuC6H4, 4-ClC6H4, etc.; R1 = n-Bu, C6H5, 2-pyridyl] were synthesized via copper nanoparticles-catalyzed amination of alcs. with anilines. Homogeneous and supported copper catalysts were studied for this reaction and given some impressive results. In this study, copper powder was found to behave as an active catalyst for alc. amination, gave better catalytic performance than metal-oxide-supported nanocopper catalysts. Catalyst characterization suggested that the copper powder could be considered as a self-supported nanocopper catalyst (i.e., nanocopper supported on copper particles). These results promoted the study of unsupported transition metal powders in sustainable catalytic reactions.3-Pyridinemethanol(cas: 100-55-0COA of Formula: C6H7NO) was used in this study.

The article was written by Liu, Yahua; Li, Yuanyuan; Zuo, Peipei; Chen, Qianru; Tang, Gonggen; Sun, Pan; Yang, Zhengjin; Xu, Tongwen. The article contains the following contents:

Viologen derivatives have been developed as neg. electrolyte for neutral aqueous organic redox flow batteries (AOFBs), but the structure-performance relationship remains unclear. Here, it was investigated how the structure of viologens impacts their electrochem. behavior and thereby the battery performance, by taking hydroxylated viologens as examples. Calculations of frontier MO energy and mol. configuration promise to be an effective tool in predicting potential, kinetics, and stability, and may be broadly applicable. Specifically, a modified viologen derivative, BHOP-Vi, was proved to be the most favorable structure, enabling a concentrated 2 M battery to exhibit a power d. of 110.87 mW cm-2 and an excellent capacity retention rate of 99.953% h-1. In the experiment, the researchers used many compounds, for example, 3-Bromopropan-1-ol(cas: 627-18-9Computed Properties of C3H7BrO)

《Selective Activation of Benzyl Alcohol Coupled with Photoelectrochemical Water Oxidation via a Radical Relay Strategy》 was published in ACS Catalysis in 2020. These research results belong to Luo, Lan; Wang, Zhou-jun; Xiang, Xu; Yan, Dongpeng; Ye, Jinhua. Category: alcohols-buliding-blocks The article mentions the following:

Selective oxidation to produce target chems. usually need activation of O2 at high temperature and/or pressure, which have largely restricted its practical operation and application. Here, we put forward a radical-relay strategy coupling photoelectrochem. (PEC) water oxidation towards efficiently selective conversion of benzyl alc. (BA) to benzaldehyde (BAD). An illuminated BiVO4 (BVO) photoanode covered with an ultrathin (∼3 nm) hydrothermally synthesized layered double hydroxide (U-LDH) catalyst and graphene (G) exhibited >99% selectivity to BAD (1.2 V vs. RHE). Mechanistic studies and DFT calculation verified that the hydroxyl radicals (•OH) generated from the oxidation of water are bound to the surface of U-LDH through hydrogen-bonding interactions and the energy is lowered. Fourier transform IR spectroscopy showed that BA is adsorbed to the U-LDH catalyst, but BAD is not. Thus, the selectivity is not only favored by the controlled oxidation capacity of •OH radicals, but the desorption of the desired product from the catalyst before further oxidation occurs. This work introduces an alternative PEC way to achieve mild and selective oxidation of BA derivatives based on ternary G@U-LDH@BVO catalysts. The results came from multiple reactions, including the reaction of (4-Bromophenyl)methanol(cas: 873-75-6Category: alcohols-buliding-blocks)

Nitrogen (N)-doped nanocarbons (NDN) as metal-free catalysts have elicited considerable attention toward selective oxidation of alcs. with easily oxidizable groups to aldehydes in the past few years. However, finding a new NDN catalytic material that can meet the requirement of the feasibility on the aerobic catalytics for other complicated alcs. is a big challenge. The real active sites and the corresponding mechanisms on NDN are still unambiguous because of inevitable coexistence of diverse edge sites and N species based on recently reported doping methods. Here, four NDN catalysts with enriched pyridinic N species and without any graphitic N species are simply fabricated via a chem.-vapor-deposition-like method. The results of XPS and X-ray absorption near-edge structure spectra suggest that the dominating N species on NDN are pyridinic N. It is demonstrated that NDN catalysts perform impressive reactivity for aerobic oxidation of complicated alcs. at an atm. pressure. Eleven kinds of aromatic mols. with single N species and tunable π conjugation systems are used as model catalysts to exptl. identify the actual role of each N species at a real mol. level. It is suggested that pyridinic N species play an unexpected role in catalytic reactions. Neighboring carbon atoms in pyridinic N species are responsible for facilitating the rate-determining step process clarified by kinetic isotope effects, in situ NMR, in situ attenuated total reflectance IR, and theor. calculation Moreover, NDN catalysts exhibit a good catalytic feasibility on the synthesis of important natural products (e.g., intermediates of vitamin E and K3) from phenol oxidation After reading the article, we found that the author used 3-Pyridinemethanol(cas: 100-55-0Related Products of 100-55-0)

Application In Synthesis of 3-Bromopropan-1-olIn 2022 ,《Spiropyran-based photo- and thermal-responsive smart polymer with controllable wettability》 was published in Polymer. The article was written by Cui, Congcong; Liu, Guojie; Gao, He; Wang, Min; Gao, Jun. The article contains the following contents:

A photo and thermal-responsive smart polymer, enabling controllable wettability according to different temperature and light conditions, was developed in this paper. The 3-(3′,3′-dimethyl-6-nitrospiro-[chromene-2,2′-indolin]-1′-yl) Pr methacrylate (SPMA) and N-isopropylacrylamide (NIPAAm) by 2,2′-azobis(isobutyronitrile) (AIBN) were grafted on the surface of polydimethylsiloxane (PDMS) to induce free radical polymerization The SPMA isomerizes from a colorless, hydrophobic spiropyran (SP) form to a deep purple, hydrophilic merocyanine form (MCMA) upon UV-light. The wettability of poly(N-isopropylacrylamide) (PNIPAAm) is sensitive to temperature, showing hydrophobicity above the low critical solution temperature (LCST) and hydrophilicity below LCST. Furthermore, the addition of SPMA has realized the significant reversible wettability synergistic with PNIPAAm. The reversible wettability can be controlled by selectively applying single or both factors of light and temperature Thus, practical application of the above controllable wettability can be greatly expanded.

Safety of 3-Bromopropan-1-olIn 2020 ,《Preparation of SiO2 grafted polyimidazole solid electrolyte for lithium-ion batteries》 was published in Ionics. The article was written by Cheng, Jiaming; Cao, Xiaoyan; Zhou, Dan; Tong, Yongfen. The article contains the following contents:

Solid electrolytes have emerged as a promising alternative to liquid electrolytes for application in solvent-free lithium rechargeable batteries. Composite polymer electrolytes based on polymer and nanoparticle exhibit acceptable ion conductivity due to the interaction between nanofillers and polymer. However, the application of composite polymer electrolytes is hindered by the agglomeration of nanofillers at high concentration Herein, in this study, the polymer electrolytes with branched polyimidazole were synthesized by radical polymerization based on functionalized SiO2 nanoparticles and imidazole monomers. Different from the reported methods of blending ceramic particles with polymers, we introduce an in situ synthesis of branched polymer electrolyte based on functionalized SiO2 nanoparticles. The stronger chem. interactions between SiO2 nanospheres and polymer chains could significantly suppress the aggregation of the nanoparticles and improve temperature stability. Among all of the electrolyte films, SiO2-MOBIm6-BF4 shows the best ion conductivity of 5.96 x 10-5 S cm-1 at 25°C and the value reaches to 9.54 x 10-4 S cm-1 at 95°C. This is mainly due to the long methylene chain increasing the flexibility of the chain segment and the mol. mobility, which is benefit to lithium-ion transportation.

The title of the article was 《Advanced Molecular Tweezers with Lipid Anchors against SARS-CoV-2 and Other Respiratory Viruses》.COA of Formula: C6H12O The author mentioned the following in the article:

The COVID-19 pandemic caused by SARS-CoV-2 presents a global health emergency. Therapeutic options against SARS-CoV-2 are still very limited but urgently required. Mol. tweezers are supramol. agents that destabilize the envelope of viruses resulting in a loss of viral infectivity. Here, we show that first-generation tweezers, I and II, disrupt the SARS-CoV-2 envelope and abrogate viral infectivity. To increase the antiviral activity, a series of 34 advanced mol. tweezers were synthesized by insertion of aliphatic or aromatic ester groups on the phosphate moieties of the parent mol. I. A structure activity relationship study enabled the identification of tweezers with a markedly enhanced ability to destroy lipid bilayers and to suppress SARS-CoV-2 infection. Selected tweezer derivatives retain activity in airway mucus and inactivate the SARS-CoV-2 wildtype and variants of concern as well as respiratory syncytial, influenza, and measles viruses. Moreover, inhibitory activity of advanced tweezers against respiratory syncytial virus and SARS-CoV-2 was confirmed in mice. Thus, potentiated tweezers are broad-spectrum antiviral agents with great prospects for clin. development to combat highly pathogenic viruses. In the experiment, the researchers used many compounds, for example, 5-Hexen-1-ol(cas: 821-41-0COA of Formula: C6H12O)

In 2022,Shi, Yinyin; Wang, Yue; Huang, Zhefan; Zhang, Fangjun; Shao, Yinlin published an article in ACS Omega. The title of the article was 《tBuOLi-Promoted Hydroboration of Esters and Epoxides》.Category: alcohols-buliding-blocks The author mentioned the following in the article:

Com. available and inexpensive lithium tert-butoxide (tBuOLi) acts as a good precatalyst for the hydroboration of esters, lactones, and epoxides using pinacolborane as a borylation agent. Functional groups such as cyano-, nitro-, amino-, vinyl, and alkynyl are unaffected under the presented hydroboration process, representing high chemoselectivity. This transformation has also been effectively applied to the synthesis of key intermediates of Erlotinib and Cinacalcet. Preliminary investigations of the mechanism show that the hydroboration proceeds through the in situ formed BH3 species. In the experimental materials used by the author, we found 3-Pyridinemethanol(cas: 100-55-0Category: alcohols-buliding-blocks)

3-Pyridinemethanol(cas: 100-55-0) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Category: alcohols-buliding-blocks
