Summary: Heterogenous carboxyl-functionalized bilayer ionic liquids/polyoxometalate catalysts were synthesized and characterized. The catalyst showed good amphiphilicity and achieved 100% sulfur removal for four model fuels without the need for extractant. The polyoxometalate and carrier had significant effects on the catalytic activities, with Keggin-type phosphotungstate and 50 nm silica being superior for desulfurization. The catalyst also demonstrated good recyclability in scale-up experiments.

Summary: This article describes two different classes of multidentate ligands (aminotriphenolate and dipyridinimine) and their corresponding metal (Ti, V, Mo, W, Fe) complexes. These catalysts efficiently activate the environmentally friendly oxidant H2O2, promoting a wide range of oxidative processes (sulfoxidations, N-oxidations, epoxidations, haloperoxidation, alcohol oxidation, hydroxylation).

Summary: Carbon-based catalysts doped with boron were synthesized using a heteroatom bridging strategy, which demonstrated enhanced catalytic performance for oxidative desulfurization of fuel oil. The presence of boron atoms as bridges for electron transfer significantly improved the activation of oxygen by graphite, leading to ultradeep oxidative desulfurization. Furthermore, the catalyst showed good recyclability with no significant decrease in desulfurization performance after five cycles.

Summary: Autoxidation of tartaric acid in air-saturated aqueous solutions in the presence of Fe(II) at low pH, 2.5, exhibits autocatalytic behavior with distinct initiation, propagation, and termination phases. The propagation phase is a chain reaction involving the activation of oxygen in the initiation stage and the generation of hydrogen peroxide. The subsequent Fenton oxidation regenerates hydrogen peroxide and contributes to a self-sustained chain reaction. The conditions for this chain reaction resemble those of a dynamical system with critical behavior, where the kinetic matrix of the pseudo-first-order reaction becomes negatively defined, resulting in exponential (chain) growth of reactive species.

Summary: A manganese-catalyzed C-H azidation reaction with high site- and enantioselectivity has been developed. This practical method enables the azidation of tertiary benzylic C-H bonds with good functional group tolerance, leading to the efficient synthesis of diverse tertiary azide-containing indolines. The generality of the method was demonstrated by applying it to secondary azide-containing indolines. The method allows for the installation of various nitrogen-based functional groups and bioactive molecules with excellent site-, chemo-, and enantioselectivity at the C3 position of indoline frameworks.

Summary: Thiols easily react with [1.1.1]propellane to give sulfur-substituted bicydo[1.1.1]pentanes in radical reactions. However, this reactivity is not observed in the case of heterocyclic thiols. In this study, electrophilic activation of [1.1.1]propellane was used to promote its iodo-sulfenylation with 10 classes of heterocyclic thiols in protocols that can be conducted on a multigram scale without exclusion of air or moisture.

Summary: In this study, CuO nanoparticles were synthesized by a simple, one-pot mechanochemical approach using the leaf extract of Seriphidium oliverianum as a reducing and stabilizing agent. The CuO NPs showed high potential for degrading water-soluble industrial dyes, with degradation rates of 65.231% +/- 0.242 for methyl green (MG) and 65.078% +/- 0.392 for methyl orange (MO). This bio-mechanochemically synthesized CuO NPs are promising candidates for efficient dye removal from water.

Summary: This study presents a series of Ce3+ complexes with counter cations ranging from Li to Cs. Cyclic voltammetry data show a significant dependence of the oxidation potential on the alkali metal identity. Analysis of the single-crystal X-ray diffraction data indicates a linear correlation between the degree of structural distortion and the measured oxidation potential. Solution electronic absorption spectroscopy confirms the reflection of structural distortion in the solution structure. Computational studies further validate this analysis.

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.
