Summary: Developing highly active, durable, and low-cost electrocatalysts for the oxygen reduction reaction (ORR) is crucial for advancing and commercializing fuel cell technologies. This study reports a novel family of Pd-Co binary alloys embedded in bimetallic organic framework-derived polyhedral carbon supports. Among the materials studied, annealed BMOF-derived Pd3Co exhibits the most promising ORR activity and stability. The strategies developed in this research provide promising insights into the rational design and synthesis of ORR electrocatalysts for alkaline fuel cells.

Summary: In this study, platinum(II) bimetallic complexes with 100% quantum yield and exceptionally short radiative decay times were reported, which are in some cases up to a hundredfold faster than analogous monometallic complexes. The use of rigid and electron donating ligands in the complexes makes them efficient phosphorescent emitters at room temperature, while the natural tendency of platinum to form metallophilic interactions and aggregates helps overcome the problem of relatively long excited-state lifetimes.

Summary: This article introduces a new series of bimetallic platinum-(II) complexes with NHC-type bridging ligands, which exhibit cytotoxicity, cell accumulation, and DNA binding properties in cancerous cells. These complexes demonstrate significant radiosensitizing effects by inhibiting DNA repair mechanisms, leading to persistent accumulation of irradiation-induced DNA damages. This study provides the first in vitro evidence for the radiosensitizing properties of NHC-platinum complexes, suggesting their potential use in combined chemo-radiotherapy protocols.

Summary: Metal N-heterocyclic carbene complexes have been demonstrated to be an important class of organometallic catalysts. This study shows a method of simultaneously introducing different NHC-M species into a single MOF, forming a dual catalyst for promoting alkyne hydration-Suzuki coupling reaction. The potential utility of this strategy is highlighted by the preparation of more new multicatalysts for various organic transformations.

Summary: Indolyl-based benzimidazolium salts were synthesized in three steps, including indole alkylation, iodine-catalyzed C-N bond coupling, and substitution. These salts exhibited high catalytic activity in Pd-catalyzed sterically hindered biaryl synthesis, with the scaffold variability adjusted by substituting indole and alkyl halides. The Suzuki-Miyaura cross-coupling of aryl chlorides was performed with good functional group tolerance, yielding biaryls in 42-87% yield at 90 degrees C using 0.5 mol% of Pd(OAc)(2)/1 i as the catalyst. The balance between the carbon chain length of substituents on the indole moiety and the steric congestion of substituents was found to be crucial for catalytic activity.

Summary: In this study, ethylenediamine modified copper-based organometallic framework was synthesized using the hydrothermal method. The materials were characterized by various techniques including SEM, XRD, FTIR, XPS, and BET. The adsorption properties of the materials for Cu (II) and Pb (II) were extensively studied through different parameters such as adsorbate concentration, ionic strength, contact time, adsorption temperature, and pH. The results showed that the maximum adsorption capacities for Cd (II) and Pb (II) were achieved at a pH value of 5.2, and the adsorption process followed pseudo second order kinetics and Langmuir isotherm model. Density functional theory calculations revealed that the chelating effect of amino groups, ion-exchange effect, and electrostatic interaction of hydroxyl groups played significant roles in improving the removal efficiency of Cd (II) and Pb (II).

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.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
