Summary: The first example of catalytic thiocarbonylation of aryliodides using CO2 has been achieved by using a combination of PdCl(2) and carbazole-derived phosphine ligands. Under mild conditions, a broad range of aryl iodides were converted to the desired thioester products in the presence of aryl or alkyl thiols (33 examples, up to 96% yields). The choice of metal, ligands, and reductant was crucial for achieving high efficiency and chemoselectivity. Moreover, this strategy provided an effective method for late-stage functionalization of biorelevant molecules.

Summary: Bi2WO6 with double active sites of tunable metallic Bi and oxygen vacancies (OV-Bi/Bi2WO6) was prepared by solvothermal treatment and used as an efficient photocatalyst for the partial oxidation of cyclohexane (CHA) to cyclohexanone (CHA-one) in air. The Bi : Bi2WO6 ratio in OV-Bi/Bi2WO6 could be tailored by controlling the solvothermal temperature, and the synergistic effect between DMF and EG increased the reduction of MDF/EG and promoted the production of Bi. OV-Bi/Bi2WO6 showed significantly enhanced photocatalytic activity attributed to its specific surface area, photo-absorption, oxygen vacancies, and efficient electron-hole separation.

Summary: In this study, novel chiral half-sandwich iridium catalysts were designed and synthesized, which enabled the preparation of a broad range of α-chiral (hetero)aryl amines with high yield and enantioselectivity. The optimized catalyst and azeotropic mixture of formic acid and triethylamine were used as the hydrogen source under mild and operationally simple conditions. This work introduced an effective chiral catalyst for the simplified synthesis of medicinally important chiral amines, and also provided a rare example of robust enantioselective transition-metal catalysis.

Summary: This paper describes a photochemical C-N coupling reaction of less reactive aryl chlorides with primary and secondary amides using a Ni catalyst without an external photocatalyst. The reaction proceeds under light irradiation (390-395 nm) with a soluble organic amine as the base, resulting in the successful synthesis of a wide range of N-aryl amides from (hetero)aryl chlorides. Mechanistic studies suggest that the amidation occurs via a Ni(I)-Ni(III) catalytic cycle.

Summary: Designing a highly active single atom catalyst, particularly noble-metal atoms in two-dimensional LDH nanostructures, is essential for speeding up the slow oxygen evolution reaction (OER). By reducing a solution, Ru single atoms (SAs) are fixed on NiFe LDH to form SARu/NiFe LDH. The activity evaluation shows that SARu/NiFe LDH exhibits higher activity and Faradaic efficiency compared to pure NiFe LDH.

Summary: A simplified treatment process is reported to convert 2D poly(ethylene oxide)/sodium alginate/tannic acid thin films into 3D-shaped moisture- and NIR light-responsive actuators. Wetting the film surface releases residual stress in a gradient manner, driving the wetted regions to bend bidirectionally. A gradient cross-linking network formed by Fe3+ ions and sodium alginate chains stabilizes the resulting 3D shape and provides moisture-responsive morphing behaviors. Fe3+ ions also enable the film to respond to NIR light by self-assembling with tannic acid molecules. Films with versatile 3D shapes and deformation modes can be conveniently fabricated using this one-step treatment process.

Summary: Designing and synthesizing highly active single atom catalysts, especially monodispersed noble-metal atoms fixed in two-dimensional layered double hydroxide (LDH) nanostructures, is crucial for accelerating the slow oxygen evolution reaction (OER). In this study, Ru single atoms (SAs) were stabilized on NiFe LDH (SARu/NiFe LDH) via an oxygen-coordinated bond after a facile solution reduction procedure. The SARu/NiFe LDH exhibits higher activity than pure NiFe LDH in basic media, with 99.3% Faradaic efficiency based on rotating ring-disk electrode measurement. This study provides a general avenue for developing efficiently monoatomic and even multiatomic catalysts in the future.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
