Summary: N,N'-Bis(trimethylsilyl)-1,4-dihydropyrazines can be used to synthesize alkylpyrazines by combining with aldehydes and tetra(n-butyl)ammonium fluoride. Various sources of alkyl substituents, such as aryl, heteroaryl, and alkyl aldehydes, can be utilized with good yields obtained from reactions with electron-rich aldehydes. DFT calculations clarified the overall reaction sequence, with the key steps being the activation of the N-trimethylsilyl moiety by fluoride and the subsequent C-C bond formation with aldehydes.

Summary: A BSA-assisted ultrasonication strategy was developed for the synthesis of stable CsPbBr3 nanocrystals (NCs) with good solubility and stability in water. The CsPbBr3 NCs were used as a fluorescence probe for rapid detection of H2S in human serum, showing a linear S2- detecting range of 10 to 800 nM and a detection limit of 7.05 nM. The method was successfully applied to determine H2S in human serum with spiked recoveries ranging from 94.98% to 102.69%. This work opens new avenues for the application of halide lead perovskite in different biosensing areas.

Summary: We investigated the differential oxidative and nucleophilic chemistry of reactive sulfur and oxygen anions using a simple reducing electrophile. The reaction with SSNO- resulted in the formation of a complex mixture of phosphorus products in the P(V) oxidation state. The selectivity for oxidation to P=S/P=O products or transformation to P-2 species was determined by the phosphine stoichiometry.

Summary: In this study, we investigated the different oxidative and nucleophilic chemistry between reactive sulfur and oxygen anions (SSNO-, SNO-, NO2-, S4(2)-, and HS-) using the reducing electrophile PPh2Cl. When SSNO- reacts with PPh2Cl, a complex mixture of mono and diphosphorus products exclusively in the P(V) oxidation state is formed. We found that the phosphine stoichiometry determines the selectivity for oxidation to P=S/P=O products or transformation to P-2 species. Interestingly, only chalcogen atoms are incorporated into the phosphorus products, while nitrogen is released as NO gas.

Summary: This study presents a nonenzymatic glycosylation reaction that forms axial S-glycosidic bonds under biorelevant conditions. By using allyl glycosyl sulfones as precursors to glycosyl radicals and taking advantage of the exceptional functional group tolerance of radical processes, various unprotected glycosyl units can be selectively introduced to cysteine residues of peptides. The method was successfully applied for direct glycosylation of complex polypeptides and proteins after developing a second-generation protocol, with computational studies performed to elucidate the reaction mechanism.

Summary: A new Ni4POM nanomaterial was developed and incorporated into a step (S)-scheme heterojunction to enhance photocatalytic activity and stability. The multielectron transfer capability of Ni4POM promotes recombination of invalid charges through the S-scheme pathway and improves resistance to photocorrosion. The optimized CZSNi-70 showed high rates of H2 and H2O2 production under visible-light irradiation. This study provides new possibilities for the development of stable and efficient transition metal-substituted POM-based S-scheme photocatalysts.

Summary: Recent studies have shown that metal-sulfur coordination compounds can regulate reactive sulfur species (RSS) transport. The reaction of B-Ph-((t)BuIm)(3)NiCl with RSS leads to the formation of square planar complexes through protonation of a carbene ligand donor atom. Mechanistic investigation suggest that protonation may occur from the decomposition of reactants, interactions with favorable counterions, or generation of transient unidentified RSS.

Summary: The first molybdenum-catalyzed highly regio- and enantioselective allylic amination of both aryl- and alkyl-substituted branched allylic carbonates has been developed. A wide variety of amines, including drugs and complex bioactive molecules, underwent successful amination with excellent reaction outcomes (up to 96% yield, >99% ee, and >20:1 b/l). The reaction could be scaled up and has been applied to the total synthesis of chiral drug molecule (S)-clopidogrel (Plavix).

Summary: This study demonstrates the significance of surface Pt atom arrangement for the efficiency of ORR in PEMFCs and reveals the correlation between Pt-Pt average distance and O2 dissociation barrier. Furthermore, the study discovers a robust correlation between the level of the catalyst's d-band center and O2 adsorption energy. High-entropy alloy substrates provide potential for controlling Pt arrangement and O2 dissociation barrier.

Summary: Cu-added gamma-Al2O3 catalysts were prepared with varying Cu loadings and the effects of copper oxidation states on catalytic activity were investigated. The results showed that the addition of copper increased the catalyst activity, but excessive copper loading decreased catalytic activity. XRD and TEM analysis indicated the formation of a solid solution of copper oxide species on the surface of gamma-Al2O3. XAS and TPR data demonstrated variations in copper oxidation states among the catalysts.

Summary: This study investigates the catalytic performance of a composite catalyst composed of ZnZrOX and H-zeolite for the hydrogenation of CO2. The deactivation of the composite catalyst is influenced by ion exchange of Zn2+ and/or coke, with their effects differing based on the zeolite structure. Separating the grains of the composite catalyst can prevent deactivation.

Summary: In this study, NiGa alloy particles supported on CeO2, ZrO2, and ZrO2-CeO2 solid solutions were prepared and characterized. The nature of the support was found to have a significant influence on the catalyst's activity and selectivity, with the crystalline structure of ZrO2 having the greatest impact. Pure ZrO2 showed the highest methanol selectivity and CO2 conversion at high Zr:Ce ratios. In equimolar and Ce-rich conditions, basic sites and oxygen vacancies were found to be the key parameters affecting methanol production.

Summary: 1,6-Hexamethylenediamine was successfully synthesized via the reductive amination of 1,6-hexanediol using a Ru/PRL(x)-Al2O3 catalyst. The highly dispersed and anchored Ru species, formed by 1,10-phenanthroline (PRL), played a crucial role in the catalytic reaction. The formation of new acid-base pairs, electron deficient Ru species, and smaller nanoparticles contributed to the improved catalytic performances of the Ru/PRL-Al2O3 catalyst.

Summary: Efficiently addressing the challenges of photocatalytic CO2 reduction to CH3OH is crucial. This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Summary: In this study, several silica-alumina catalysts modified with Ag were examined for the dehydration of 1,3-butanediol to 1,3-butadiene. Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
