Summary: This study investigates the structural characteristics and interaction energies of the halogen bond between heteronuclear halogens (ClF, BrCl, IBr, ICl, BrF, and IF) and benzene using density functional theory. The results show that the interaction energies increase with the polarity between the atoms and are proportional to the angles between the Z axis and the covalent bond of the heteronuclear halogen. The electron density and Laplacian values indicate that the interaction is a long-range weak interaction similar to a hydrogen bond. The main interaction in the complexes varies depending on the halogen species, with van der Waals forces dominating in some and electrostatic interactions dominating in others.

Summary: The study presents an electrochemically mediated method for the preparation of 2,1-benzoxazoles from o-nitro-phenylacetylenes. In contrast to traditional electrochemical reduction of nitro to nitroso, the nitro group directly undergoes cyclization reaction with the alkyne activated by selenium cation generated by the anodic oxidation of diphenyl diselenide to produce the desired products.

Summary: This study introduces a novel method for controlling the stereochemistry of dinucleotide synthesis using chiral phosphoric acid catalysts, achieving control over the stereogenic phosphorous centers and unprecedented levels of diastereodivergence. The method utilizes two different CPA scaffolds to achieve stereodivergence and does not require stoichiometric activators or chiral auxiliaries, making it a convenient and efficient asymmetric catalysis method for the synthesis of diastereomeric dinucleotides and cyclic dinucleotides of interest in immuno-oncology.

Summary: In this study, a catalytic one-step synthesis of cyclopropenium cations using readily available alkynes and hypervalent iodine reagents as carbyne sources is reported. A novel Rh-carbynoid catalytically generates monovalent cationic carbynes (:C+-R), which are then transferred to alkynes via an oxidative [2+1] cycloaddition, resulting in a new type of ester-substituted CPC. This method allows for regioselective attack of various carbon and heteroatomic nucleophiles, providing a new platform for the synthesis of valuable cyclopropenes that are difficult or impossible to make by current methodologies.

Summary: 2,3-disubstituted benzofurans with potential for pharmaceutical applications are effectively synthesized by Ni complexes via intramolecular C-O bond activation. The reaction pathway of the catalytic cycle has been studied using density functional theory (DFT) calculations. It was found that the rate-determining step is the reductive elimination of the product. A key finding is that coordination to an alkynyl group of another substrate occurs simultaneously with elimination, enhancing the thermodynamic stability of the product and determining the reaction pathway of the catalytic cycle. The reductive elimination assisted by solvent molecules or free ligand results in an endergonic reaction. This result can be considered as a self-cocatalytic effect of the substrate and adds a new perspective to the design of catalytic reaction systems with effective catalytic cycles.

Summary: An electrochemical method for the synthesis of 2-aminothiazoles via aryl ring construction using enaminones and thioureas is reported. The cascade enamine C-H thiolation and C-N amination constitutes a major transformation for the thiazole ring formation. Moreover, a simple modification of electrochemical conditions enables the tunable dearomatization of the thiazole ring via vicinal dialkoxylation, leading to the synthesis of 4,5-dialkoxyl thiazolines bearing a quaternary carbon center with excellent diastereoselectivity.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
