Article Abstract
This review examines the role of ionic liquids (ILs) in the catalytic carbonation of epoxides for the synthesis of cyclic carbonates, focusing on the key factors that influence reaction efficiency. The nucleophilicity and basicity of the anions in IL catalysts are highlighted as critical components for promoting the cycloaddition reaction with CO. The solubility and ionicity of the ILs also significantly affect the reaction, with higher ionicity leading to better solubilization and catalytic performance. Additionally, the review emphasizes the importance of the water content in influencing solvation and the generation of nucleophilic species, particularly in hydrophilic IL environments. Mechanistic studies, supported by density functional theory (DFT) calculations, provide insight into the reaction pathways, although more detailed kinetic data are required. The induction period observed in some reactions suggests the formation of ionic nucleophilic species, but it is still premature to draw definitive conclusions regarding the effects of various reaction parameters. The review calls for further exploration of the kinetic data and competitive experiments to fully understand the role of ILs in epoxide carbonation.

We report the synthesis and reactivity of phenylpyridine-based boron azides readily accessible via nucleophilic substitution from generated borenium-type precursors. Three azides were obtained: a hydridic species (L)BHN (L = 2-phenylpyridine), a cyclopentyl-substituted analogue (L)B(cyclopentyl)N, and a boron diazide (L)B(N) obtained as a byproduct from the synthesis of (L)BHN. The prepared borane azides exhibit notable thermal and photochemical robustness, with decomposition temperatures around 140 °C in mesitylene solution and above 170 °C in the solid state, as evidenced by DSC/TGA analysis.

Producing olefins by carbon dioxide (CO) hydrogenation is a long-standing goal. The usual products are multicarbon mixtures because the critical step of heterolytic hydrogen (H) dissociation at high temperatures complicates selectivity control. In this study, we report that irradiating gold-titanium dioxide at 365 nanometers induces heterolytic H dissociation at ambient temperature.

In this study, a novel riboflavin-mediated nanoscale zero-valent iron/peracetic acid system (RF/nZVI/PAA) was constructed to increase the removal of norfloxacin. Under the optimal conditions (PAA=10 mg/L, nZVI=20 mg/L, RF= 1 mg/L, and initial pH =4), complete norfloxacin removal was achieved within 30 min, accompanied by a 70 % mineralization rate. Electron paramagnetic resonance spectroscopy combined with quenching experiments quantitatively identified hydroxyl radical, carbon-centered radical, and singlet oxygen as the predominant reactive oxidative species (ROS) responsible for norfloxacin removal, with contributions of 42 %, 44 %, and 10 %, respectively.

Protein delivery has emerged as a powerful therapeutic tool to treat many life-threatening diseases. In this study, we report the synthesis of a protein (Lysozyme = LYS)-supramolecular-structure-directing-unit (SSDU) conjugate using a redox-responsive self-destructive linker, its spontaneous self-assembly in water, intracellular delivery, and selective killing of cancer cells. The LYS surface has a few (on average 6) free amine groups, which were used to attach with the SSDU consisting of a hydrazide-functionalized naphthalene-diimide (NDI) chromophore through a urethane linkage, producing a LYS-NDI conjugate having 3 NDI chromophores on average per protein.

A new alumaborane compound containing a {AlH-BH} functional group has been prepared by reaction of the aluminium(I) complex [{(ArCMeN)CH}Al] (Ar = 2,6--PrCH) with a boron dihydride species supported by an anionic chelating κ-, ligand. Spectroscopic analysis of the product suggests that it exists as a mixture of isomers in solution with the ligand on boron coordinating in both a κ and κ fashion. The dialumane analogue, containing a {AlH-AlH} functional group, was also prepared.
