Summary: This study reports the observation of cis-HPPH, trans-HPPH, and PPH2 as the laser photolysis products of phosphine (PH3) and diphosphine (P2H4) in solid N-2- and Ar-matrices at 10 K. The identification of these P2H2 isomers is supported by matrix-isolation IR and UV/Vis spectroscopy, D-isotope labeling, and quantum chemical calculations. Bonding analyses reveal that HPPH features standard PP double bonds, while PPH2 exhibits a partial PP triple bond due to the H2P <- P pi bonding interaction.

Summary: We described a simple and metal-free protocol for the synthesis of [1,2,3]triazolo[1,5-a]quinoline 3-carboxamides. The synthesis involves two steps, with the first step utilizing organocatalysis and the second step involving the use of an inorganic base. The reactions were performed in dimethylsulfoxide as solvent at 70°C for 2 hours. The synthetic protocol yielded a variety of [1,2,3]triazolo[1,5-a]quinoline 3-carboxamides in good to excellent yields (63-96%) for secondary compounds and moderate to good yields (48-76%) for tertiary compounds.

Summary: A one-pot tandem approach to [1,2,3]triazolo[1,5-a]quinolines was developed from (E)-s-chlorovinyl ketones and 2-azidoaryl carbonyls using a sequence of alpha-vinyl aldol and azide- alkyne cycloaddition reactions. The intramolecular azide-alkyne cycloaddition of allenol intermediates was promoted by NEt3 and nickel catalysts. The [1,2,3]triazolo[1,5-a]quinolines are important precursors to alpha-diazoimines and can provide valuable heterocyclic compounds through denitrogenative transformations.

Summary: The optical properties of phosphorus clusters are analyzed using first-principles calculations. It is found that phosphorus clusters exhibit strong light absorption in the ultraviolet region while remaining transparent in the visible to far-infrared bands. The third-order nonlinear optical performance of phosphorus clusters surpasses that of p-nitroaniline with a D-π-A structure. A practical approach for enhancing nonlinear optical effects in a medium via atom replacement and its application to hydride systems are discussed.

Summary: The aim of this study is to experimentally connect the interatomic exchange-correlation energy with the energy decomposition method IQA. The nuclear magnetic resonance (NMR) J-coupling constant 3J(H,H ') is identified as a suitable experimental quantity due to its strong correlation with QTAIM's delocalization index (DI). By investigating the correlations between 3J(H,H ') and a relevant dihedral angle in several compounds, it is concluded that the inter-hydrogen exchange-correlation energy Vxc(H,H ') shows the best agreement with experiment, especially when multiplied with the internuclear distance RHH '.

Summary: In this study, the authors address the argument raised in a previous comment regarding the energy of the NO3 radical and its impact on the reaction profiles of the NO3 radical with various compounds. They used 49 DFT functionals to obtain the optimized geometry of the NO3 radical and compared the results from different functionals. The thermodynamic values of three reactions were calculated using the functionals with smaller errors and compared with experimental data. The authors also recalculated the barriers of the reactions using these functionals and observed a difference of 10.5 kJ mol(-1) compared to the results obtained with the M08HX functional.

Summary: This work presents the synthesis of aryl and alkenyl halides from fluorosulfonates using commercially available ruthenium catalysts. It is the first study to efficiently convert phenols to aryl halides with chloride, bromide, and iodide. Fluorosulfonates can be easily prepared using sulfuryl fluoride (SO2F2) and cost-effective substitutes for triflates. Additionally, this work also reports an efficient coupling of alkenyl fluorosulfonates for the first time. Representative examples demonstrate that the reaction can be carried out in a one-pot process, starting directly from phenol or aldehyde.

Summary: Carbon dioxide solid sorbents produced from mesoporous functionalized silica microparticles (SBA-15) were theoretically studied using density functional theory and empirically evaluated for their CO2 adsorption capacity. Different types of organosilyl groups were tested, and SBA-15 bearing (3-aminopropyl)triethoxysilane (APTES) showed significant enhancement in CO2 adsorption compared to pristine SBA-15. The maximum adsorption capacity under conditions relevant to CO2 capture was increased from 0.34 mmol/g (SBA-15) to 1.15 mmol/g (SBA-15@NH2).

Summary: Multiply charged complexes bound by noncovalent interactions have been studied in organic and main group inorganic systems. In this work, we investigate similar complexes in organometallic systems containing transition metals and provide insights into their existence. Our results reveal that carboxylic acid-containing dimers are more strongly bonded and have higher barriers to dissociation compared to amide ones, and cationic complexes are more stable than anionic ones. Additionally, we report a symmetric proton transfer in the metastable phase.

Summary: This study investigated the synthesis, acid-base behavior, and anion recognition of neurotransmitters (dopamine, tyramine, and serotonin) using aza-scorpiand ligands functionalized with hydroxyphenyl and phenyl moieties (L1-L3 and L4, respectively). The results showed that L1 selectively recognized serotonin at physiological pH due to complementary hydrogen bonding, p-p, and cation-p interactions, leading to stabilization of the receptors. NMR and molecular dynamics studies revealed rotation blockage in the neurotransmitter side chain upon complexation with L1.

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.
