Summary: An atroposelective Ir-catalyzed dynamic kinetic resolution (DKR) of 2-(quinolin-8-yl)benzaldehydes/1-naphthaldehydes is achieved by transfer hydrogenative coupling of allyl acetate. The reaction leads to the installation of central and axial chirality, with high diastereoselectivities and excellent enantioselectivities when ortho-cyclometalated iridium-DM-BINAP is used as the catalyst. The racemization of the substrates is facilitated through a designed transient Lewis acid-base interaction between the quinoline nitrogen atom and the aldehyde carbonyl group.

Summary: Optically active organosilanes have been demonstrated to be versatile chiral reagents in synthetic chemistry. Monohydrosilanes, which bear a Si-H bond, are especially unique due to their facile transformations through stereospecific bond-formation reactions. In addition, they have also been used as chiral reagents for alcohol resolution, chiral auxiliaries, mechanistic probes, and potential optoelectronic materials.

Summary: An efficient and rapid method for constructing a family of axially chiral sulfonamides with a wide functional group tolerance has been developed through Pd-catalyzed atroposelective hydroamination. Simple oxidation and gamma-addition enabled the synthesis of various valuable axially chiral sulfonamides and anilides, including non-natural amino acid derivatives. Preliminary DFT calculations were used to explain the origin of asymmetric induction.

Summary: 3D metallaelectro-catalyzed C-H activation is a promising strategy to obtain valuable organic molecules in an economically and environmentally friendly manner. However, achieving enantioselective C-H activation using 3D metals is challenging and has limited progress. In this study, we combined cobaltaelectro-catalyzed C-H activation with asymmetric catalysis to achieve highly enantioselective annulation of allenes, resulting in a wide range of chiral compounds with good yields and high enantioselectivities. This approach demonstrated practicality by diversifying complex bioactive compounds and drug molecules, as well as conducting large-scale enantioselective electrocatalysis in continuous flow.

Summary: The corrosion inhibition performance of two pyrazole derivatives, namely N-((1H-pyrazol-1-yl)methyl)pyri midin-2-amine (PPA) and 2-(((1H-pyrazol-1-yl)methyl)amino)benzoic acid (PMB), was assessed on carbon steel (CS) in 1 M HCl medium using various techniques. The results showed that the inhibition efficiencies increased with the concentration of inhibitor but decreased with temperature. PPA exhibited anodic behavior while PMB showed mixed behavior. The adsorption of inhibitor molecules on the CS surface led to an increase in charge transfer resistance. The formation of an adsorption-related protective inhibitor film was observed through SEM-EDX analysis. Theoretical studies using DFT and MDS supported the experimental findings.

Summary: In this study, new substituted ligands based on pyrazole (L-1-L-4) were synthesized via a one-step condensation reaction. These ligands formed in situ complexes with various copper (II) salts, and catalyzed the oxidation of catechol to o-quinone. The catalytic activity depended on the ligand, counterion, and solvent. The complex formed by L-2 and Cu(CH3COO)(2) exhibited the highest catalytic activity in methanol.

Summary: Helical perovskite nanocrystals (H-PNCs) were grown inside nanometric helical porous silica, with their handedness determined by the templates. The H-PNCs exhibit strong induced circular dichroism (CD) and circularly polarized luminescence (CPL) signals, with high dissymmetry g-factors. The circular dichroism originates from the chiral shape of the H-PNCs, as demonstrated by simulations.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
