Summary: Asymmetric hydrogenation of double bonds is an effective method for preparing chiral molecules, with noble metals and bidentate ligands showing remarkable reactivity. The development of chiral tridentate ligands has become increasingly important, enabling both reactivities and stereoselectivities in asymmetric hydrogenation. While noble metal catalysts with chiral tridentate ligands have made significant achievements, there is still a high demand for designing chiral tridentate ligands for earth abundant metal catalysts.

Summary: The synthesis of anilido-aldimine Cu(II) complexes was achieved by the treatment of 2-(ArNC(H))C6H4-HNC9H6N with n-BuLi and subsequent addition of CuCl2. The complexes were characterized by various spectroscopic techniques, and X-ray diffraction analysis showed that complexes 2 and 4 are mononuclear with slightly square-planar geometries. These Cu(II) complexes exhibited excellent catalytic activity in the Chan-Lam coupling reactions of benzimidazole derivatives with arylboronic acids, with yields up to 96%.

Summary: Nitrogen oxides play a significant role in environmental pollution, highlighting the importance of developing techniques to treat these gas emissions. The selective catalytic reduction of NOx with carbon, instead of NH3, is a promising alternative technology. This study focuses on synthesizing carbon catalysts that are effective in reducing NO emissions. Surface modifications, including introducing nitrogen and oxygen functionalities and copper as a metallic phase, significantly enhance the catalytic activity. The optimal copper-to-carbon mass ratio of 10% leads to 100% NO conversion at 440 degrees C, indicating the high performance of the AC_M_BM@10Cu catalyst. The presence of N2 and CO2 was confirmed, while N2O and CO were not detected. Some catalyst deactivation was observed after 38 hours of reaction.

Summary: Two NNN pincer complexes of Cu(II) and Ni(II) with BPIMe- ligands were synthesized and characterized structurally, spectroscopically, and electrochemically. The complexes displayed catalytic activity for the reduction of CO2, with the Cu(II) complex showing higher activity than the Ni(II) complex. However, both complexes decomposed into copper and nickel metal on the electrode surface during extended reductive electrolysis, indicating the role of ligand reduction in electrocatalysis and decomposition processes.

Summary: The bidentate ligand TzPy showed noninnocent behavior and could be modified by dienophiles. The kinetic analysis of the reaction between [1](+) and ViFc yielded Delta G double dagger(298 K) = 67 kJ mol(-1), while that of [1](+) and EthFc was Delta G double dagger(298 K) = 83 kJ mol(-1). The electrochemical reduction mechanism of [1Fc](+) was studied using cyclic voltammetry and UV-vis SEC experiments, supported by DFT calculations.

Summary: In the past decade, gasotransmitters NO· and H2S have been extensively studied in biological contexts, uncovering their biosynthesis and physiological effects. There is believed to exist a complex crosstalk between these compounds and related species in physiological conditions. Iron porphyrins as heme enzymes play a central role in catalyzing key interconversions, with interactions with sulfide and nitric-oxide-related species being described in this work. The stability and reactivity of mixed ternary systems are also discussed along with future perspectives.

Summary: Sensing important metals in different environments is vital, and the use of fluorescent sensors in metal sensing is a widely applied method. This study introduces a phenothiazine-based fluorescent sensor for Cu(II) ions, which shows high selectivity compared to other transition metal salts. The Lewis acidity of the Cu(II) salt and a 1:1 ratio were found to enhance the sensing response in MeOH solvent.

Summary: A series of tridentate polypyridyl N^N^N/N^C^N-coordinating ligands (R1, R2, L1, L2) were synthesized using palladium-catalyzed Suzuki-Miyaura C-C bond-forming and N-methylation reactions with high yields (70-97%). The ligands were characterized using various analytical techniques, and their electrochemical and photophysical properties were investigated. Theoretical calculations were also performed to study the optoelectronic properties of these compounds. Some of the ligands exhibited mixed or pure luminescence transitions. Charged ligands (L3 and L4) were used as selective chemosensors for the detection of Cu(II) and Fe(II) ions with high sensitivity.

Summary: Bis[dibenzobismepine], a dibismuthane composed of two bismepine units, was synthesized and characterized. Its reactions with diphenyl dichalcogenides, dibenzoylperoxide, and elemental chalcogens were investigated, and the products were isolated and characterized. The potential of these compounds to act as tridentate chalcogen/olefin ligands with bismuth atoms as structure-determining elements in the backbone was explored using theoretical approaches.

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.
