Copper-Catalyzed Three-Component Aminofluorination of Alkenes and 1,3-Dienes: Direct Entry to Diverse β-Fluoroalkylamines was written by Feng, Guangshou;Ku, Colton K.;Zhao, Jiaqi;Wang, Qiu.

Rapid and efficient access to structurally diverse β-fluoroalkylamines is in high demand, due to their wide presence and great importance in medicinal chem. and drug development. Direct 1,2-aminofluorination of alkenes offers an ideal strategy for one-step entry to β-fluorinated amines from readily available starting materials. Yet the synthesis of valuable β-fluorinated alkylamines remains an unsolved challenge, due to the inherent incompatibility between electrophilic fluoride sources and the electron-rich alkylamines. Herein, an unprecedented, catalytic, three-component aminofluorination of diverse alkenes and 1,3-dienes, which has been achieved by an innovative copper-catalyzed electrophilic amination strategy using O-benzoylhydroxylamines as alkylamine precursors, is reported. The use of Et3N·3HF is also critical, not only as a com. available and inexpensive fluoride source to enable effective fluorination but also as an acid source for the formation of aminyl radical cations for electrophilic amination. Mechanistic experiments suggest the involvement of aminyl radical species and carbon-radical intermediates under reaction conditions. This method features high regioselectivity and good tolerance of diverse functional groups and provides a practical and direct entry to a broad range of β-fluorinated electron-rich alkylamines. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4COA of Formula: C10H2CuF12O4).

Polymer-stretching photoluminescent regulation by doping a single fluorescent molecule was written by Gu, Fan;Li, Yuanhao;Jiang, Tao;Su, Jianhua;Ma, Xiang. And the article was included in CCS Chemistry in 2022.Recommanded Product: Copper(II) trifluoromethanesulfonate This article mentions the following:

Photoluminescent materials play an essential part in the application of polymer systems. However, intrinsic polymer systems have rarely been intuitively interpreted based on photoluminescent regulation. A novel photoluminescent mechanism called vibration-induced emission (VIE) has recently garnered considerable attention due to its multicolor fluorescence from a single mol. entity. Based on the unique fluorescent properties of VIE mols., we have doped 9,14-diphenyl-9,14-dihydrodibenzo[a, c]-phenazine (DPAC) and its derivative DPAC11-carbonitrile in two stretchable polymers, poly (ε-caprolactone) and ethylene vinyl acetate (EVA) copolymer, to explore the important relationship between luminophores and polymer systems. This research focuses on the multicolor photoluminescence of the blend films that result from stretching exertions and temperature responses. The successive conformational alterations of VIE mols. endow continuous photoluminescent changes. Meanwhile, the multicolor variations also provide specific visual evidence regarding the amplified tensile stresses and microstructural changes in the polymer. This demonstration therefore provides advantageous insight into the development of functional optical materials.

And the article was included in Surfaces and Interfaces in 2022.Electric Literature of CuH2O2 This article mentions the following:

Significant research efforts are being devoted to achieve metal-organic framework (MOF) thin films with tailored film thickness and high stability on solid substrates. We demonstrate the successful synthesis of uniform Cu-BTC films directly on a copper metal substrate, using rapid and efficient heat treatment assisted by a nanosecond laser. An oxidized copper substrate with an organic ligand is irradiated by the second harmonic of Nd3+:Y3Al5O12 laser (532 nm), thereby forming Cu-BTC thin films through the photothermal process. The temperature of the laser-irradiated surface was estimated using COMSOL Multiphysics, aiding the optimization of the laser energy d. for Cu-BTC crystal growth. The prepared Cu-BTC films exhibit a high surface area (985 m2/g) at 30 mJ/cm2, with a peak surface temperature of 鈭?64 K. Notably, 3000 laser shots generate Cu-BTC films with a thickness of 10渭m. Thus, the study offers a novel fabrication method for a design strategy, involving the rapid growth (鈭?2 min) of MOF thin films on metal substrates.

The development of advanced electrode materials and the combination of aptamer with them have improved dramatically the performance of aptasensors. Herein, a new architecture based on copper hydroxide nanorods (Cu(OH)2 NRs) are directly grown on the surface of screen printed carbon electrode (SPCE) using a two-step in situ, very simple and fast strategy and was used as a high-performance substrate for immobilization of aptamer strings, as well as an electrochem. probe to development a label-free electrochem. aptasensor for SARS-CoV-2 spike glycoprotein measurement. The Cu(OH)2 NRs was characterized using X-ray Diffraction (XRD) and electron microscopy (FESEM). In the presence of SARS-CoV-2 spike glycoprotein, a decrease in Cu(OH)2 NRs-associated peak current was observed that can be owing to the target-aptamer complexes formation and thus blocking the electron transfer of Cu(OH)2 NRs on the surface of electrode. This strategy exhibited wide dynamic range in of 0.1 fg mL-1 to 1.2渭g mL-1 and with a high sensitivity of 1974.43渭A mM-1 cm-2 and low detection limit of 0.03 卤 0.01 fg mL-1 of SARS-CoV-2 spike glycoprotein deprived of any cross-reactivity in the presence of possible interference species. In addition, the good reproducibility, repeatability, high stability and excellent feasibility in real samples of saliva and viral transport medium (VTM) were found from the provided aptasensor. Also, the aptasensor efficiency was evaluated by real samples of sick and healthy individuals and compared with the standard polymerase chain reaction (PCR) method and acceptable results were observed In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Computed Properties of CuH2O2).

This study estimated health risks due to two types of copper-based nanoagrochems. (Cu (OH)2 and CuO nanoparticles (NPs)), during inadvertent ingestion of soil and consumption of leafy vegetables for a hypothetical exposure scenario. The dissolution of copper-based nanoagrochems. in human digestive system was considered for estimating realistic doses. No risk was found during soil ingestion (hazard quotient (HQ) <1). HQ (no dissolution of Cu (OH) 2 nanopesticides) (HQ= 0.015) comes out to be 2 times higher than that of HQ (100% dissolution of Cu (OH)2 nanopesticides into copper ions) (HQ= 0.007). In case of risk from consumption of leafy vegetables, the following order of risk was found (high to low HQ value): Cu (OH)2 (HQ= 1925) >CuO NPs (1402). Combined exposure of Cu (OH)2 nanopesticide through soil ingestion as well as consumption of contaminated edible leafy vegetables resulted in health risks. The calculated maximum allowable applicable concentration values of Cu (OH)2 and CuO NPs without posing risk to human and plant toxicity were found to be 1.14 and 0.45 mg/L, resp. These findings can be used now for deciding safe use of copper-based nanoagrochems.
