The article was titled 《Efficient Ion Sieving in Covalent Organic Framework Membranes with Sub-2-Nanometer Channels》.Category: alcohols-buliding-blocks The article contains the following contents:

Membranes of sub-2-nm channels show high ion transport rates, but it remains a great challenge to design such membranes with desirable ion selectivities for ion separation applications. Here, covalent organic framework (COF) membranes with a channel size of ≈1.4 nm and abundant hydrogen bonding sites, exhibiting efficient ion sieving properties are demonstrated. The COF membranes have high monovalent cation permeation rates of 0.1-0.2 mol m-2 h-1 and extremely low multivalent cation permeabilities, leading to high monovalent over divalent ion selectivities for K+/Mg2+ of ≈765, Na+/Mg2+ of ≈680, and Li+/Mg2+ of ≈217. Exptl. measurements and theor. simulations reveal that the hydrogen bonding interaction between hydrated cations and the COF channel wall governs the high selectivity, and divalent cations transport through the channel needs to overcome higher energy barriers than monovalent cations. These findings provide an effective strategy for developing sub-2-nm sized membranes with specific interaction sites for high-efficiency ionic separation The experimental process involved the reaction of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Category: alcohols-buliding-blocks)

The title of the article was 《Rhodium-Catalyzed Asymmetric Hydrogenation of All-Carbon Aromatic Rings》.Recommanded Product: 89466-08-0 The author mentioned the following in the article:

Compared with heteroarenes, homogeneous asym. hydrogenation of all-carbon aromatic rings is a longstanding challenge in organic synthesis due to the strong aromaticity and difficult enantioselective control. Herein, authors report the rhodium/diphosphine-catalyzed asym. hydrogenation of all-carbon aromatic rings, affording a series of axially chiral cyclic compounds with high enantioselectivity through desymmetrization or kinetic resolution In addition, the central-chiral cyclic compounds were also obtained by asym. hydrogenation of phenanthrenes bearing a directing group. The key to success is the introduction of chiral diphosphine ligands with steric hindrance and strong electron-donating properties. The axially chiral monophosphine ligands could be obtained by simple conversion of the hydrogenation products bearing the phosphine atom.

The title of the article was 《pH/ROS dual-sensitive and chondroitin sulfate wrapped poly (β-amino ester)-SA-PAPE copolymer nanoparticles for macrophage-targeted oral therapy for ulcerative colitis》.Formula: C4H11NO The author mentioned the following in the article:

An oral nanoparticle (NPs) encapsulated in chitosan/alginate hydrogel (CA-Gel) with dual-sensitive in pH and reactive oxygen species (ROS) was developed to load curcumin (CUR) based on the intracellular-specific characteristics of macrophages. Chondroitin sulfate (CS) wrapped PBAE-SA-PAPE with intracellular pH/ROS dual-sensitive characteristics and CUR via a simple nanopptn. method to form NPs (CS-CUR-NPs), and mixed CA-Gel to acquire the final preparation (CS-CUR-NPs-Gel). CS-CUR-NPs displayed an ideal average particle size (179.19 ± 5.61 nm) and high encapsulating efficiency (94.74 ± 1.15%). CS showed a good targeting ability on macrophages and the CA-Gel contribution in protecting NPs from being destroyed in the upper gastrointestinal tract. As expected, CS-CUR-NPs-Gel could significantly alleviate inflammation in DSS-induced UC mice via TLR4-MAPK/NF-ΚB pathway. This study is the first to attempt to design a novel pH/ROS dual-stimulated release strategy in helping intracellular CUR delivery and anticipated for efficient anti-UC therapy.

In 2022,Tu, Chenhao; Ma, Nana; Xu, Qingli; Guo, Wenyue; Zhou, Lanxin; Zhang, Guisheng published an article in International Journal of Quantum Chemistry. The title of the article was 《Computational study on the mechanism of metal-free photochemical borylation of aryl halides》.Category: alcohols-buliding-blocks The author mentioned the following in the article:

C-radical borylation is a significant approach for the construction of carbonboron bond. Photochem. borylation of aryl halides successfully applied this strategy. However, precise mechanisms, such as the generation of aryl radicals and the role of base additive (TMDAM) and water, remain controversy in these reactions. In this study, photochem. borylation of aryl halides has been researched by d. functional theory (DFT) calculations Indeed, the homolytic cleavage of the CX bond under irradiation with UV-light is a key step for generation of aryl radicals. Nevertheless, the generation of aryl radicals may also undergo the process of single electron transfer and the heterolytic carbonhalogen bond cleavage sequence, and the latter is favorable during the reaction. The experimental process involved the reaction of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Category: alcohols-buliding-blocks)

In 2022,Corpas, Javier; Gomez-Mendoza, Miguel; Ramirez-Cardenas, Jonathan; de la Pena O’Shea, Victor A.; Mauleon, Pablo; Gomez Arrayas, Ramon; Carretero, Juan C. published an article in Journal of the American Chemical Society. The title of the article was 《One-Metal/Two-Ligand for Dual Activation Tandem Catalysis: Photoinduced Cu-Catalyzed Anti-hydroboration of Alkynes》.Related Products of 7748-36-9 The author mentioned the following in the article:

A dual catalyst system based on ligand exchange of two diphosphine ligands possessing different properties in a copper complex has been devised to merge metal- and photocatalytic activation modes. This strategy has been applied to the formal anti-hydroboration of activated internal alkynes via a tandem sequence in which Cu/Xantphos catalyzes the B2pin2-syn-hydroboration of the alkyne whereas Cu/BINAP serves as a photocatalyst for visible light-mediated isomerization of the resulting alkenyl boronic ester. Photochem. studies by means of UV-vis absorption, steady-state and time-resolved fluorescence, and transient absorption spectroscopy have allowed characterizing the photoactive Cu/BINAP species in the isomerization reaction and its interaction with the intermediate syn-alkenyl boronic ester through energy transfer from the triplet excited state of the copper catalyst. In addition, mechanistic studies shed light into catalyst speciation and the interplay between the two catalytic cycles as critical success factors. The results came from multiple reactions, including the reaction of Oxetan-3-ol(cas: 7748-36-9Related Products of 7748-36-9)

Name: 3-PyridinemethanolIn 2019 ,《Uniform silver nanoparticles on tunable porous N-doped carbon nanospheres for aerobic oxidative synthesis of aryl nitriles from benzylic alcohols》 was published in Applied Organometallic Chemistry. The article was written by Hashemi, Alireza Nemati; Eshghi, Hossein; Lamei, Kamran. The article contains the following contents:

Tunable N-doped carbon nanospheres were prepared from sucrose as carbon source and tris(2-aminoethyl)amine (TAEA) as nitrogen source by a simple and easily reproducible method. It was demonstrated that the tunable N-doping of carbon spheres could be realized by altering the ratio of TAEA in the raw materials. The content of doped nitrogen, surface area, pore volume and pore size of carbon nanospheres were increased with the increasing of TAEA amount in the hydrothermal process.
