Herein, we report that highly chemoselective and enantioselective reduction of 2-vinyl-substituted pyridines has been achieved for the first time. The reaction, which uses chiral spiro-bicyclic bisboranes as catalysts and HBpin and an acidic amide as reducing reagents, proceeds through a cascade process involving 1,4-hydroboration followed by transfer hydrogenation of a dihydropyridine intermediate. The retained double bond in the reduction products permits their conversion to natural products and other useful heterocyclic compounds by simple transformations.

Selective catalytic S_NAr reaction of polyfluoroaryl C-F bonds with chloride is shown. Stoichiometric TMSCl makes the reaction exergonic and allows catalysis, which involves ground state elevation of chloride, aromatic donor-acceptor interactions, and stabilization of the Meisenheimer complex. Traditional cross-coupling of the products is now possible and demonstrates the utility. Thus, e.g., treatment of pentafluoropyridine with TMSCl and benzyltributylammonium chloride afforded 4-chloro-2,3,5,6-tetrafluoropyridine (95%).

A neg. electrode material of nano V nitride/interconnected porous C (Nano-VN/IPC) is fabricated via a novel method combining surface-initiated electrochem. mediated ATRP and heat-treatment process. The structural and composition characterization display that a low crystallinity of VN nanoparticles was obtained, which distributes uniformly in the interconnected pores of the C scaffold materials. The high-distribution of nano-VN particles in the interconnected pores significantly enhances the usage efficiency of the electrochem.-active materials to ensure the high electrochem. performance of the electrode materials. The interconnected pore structure is convenient for diffusion and transfer of electrolyte ions during charging-discharging process. The Nano-VN/IPC electrodes exhibit a high specific capacitance of 284.0 F/g at 0.5 A/g in 2 M KOH aqueous electrolyte with a low resistance and good rate capability. An asym. supercapacitor is assembled with Ni(OH)₂ and Nano-VN/IPC electrodes as the pos. and neg. electrodes. The device presents a high specific capacitance of 122 F/g at the c.d. of 0.5 A/g, and when the c.d. increases to 5 A/g the capacitance still remains 70 F/g. Remarkably, the device delivers an ultrahigh power d. of 35.6 Wh/kg at a power d. of 362.5 W/kg.

The ecol. and human health threats brought by emerging pollutants are increasingly serious. Development of efficient removal methods is urgent. Herein, seven deep eutectic solvents (DESs) composed by quaternary ammonium salts and lactic acid or glycolic acid were synthesized and used to regulate magnetic (Fe₃O₄) metal organic framework (MUiO-66-NH₂) composites. The obtained nanoparticles (named as DES-MUiO-66-NH₂) were used as adsorbents to adsorb pharmaceuticals and personal care products (PPCPs). Langmuir isotherm model and pseudo-second-order kinetics model were suitable to analyze the adsorption process of DES-MUiO-66-NH₂ to PPCPs, indicated that the adsorption of PPCPs was chemisorption on homogeneous surface of DES-MUiO-66-NH₂ adsorbents. Under the optimal conditions, the adsorption capacity of DES-MUiO-66-NH₂ toward ofloxacin and mefenamic acid reached up to 97.60 and 79.22 mg/g, resp. Mechanism exploration indicated that DES-MUiO-66-NH₂ selectively adsorbed PPCPs through electrostatic interaction, chelation, π-π stacking, hydrophobic interaction and hydrogen bonding. D. functional theory proved the chelation through theor. calculation Selective experiments manifested that the structures of DESs directly determined the specificity of DES-MUiO-66-NH₂ for different PPCPs, and the investigation of structure-activity relationship provided new ideas for designing efficient tailor-made adsorbents for PPCPs. The proposed PPCPs removal approach focused on the guiding role of DESs in selective adsorption. And this green DESs regulation idea provided more options for the synthesis of high-efficiency and functional adsorbents for emerging pollutants.

Wei, Xiaoxiao published the artcileFabrication of di-selective adsorption platform based on deep eutectic solvent stabilized magnetic polydopamine: Achieving di-selectivity conversion through adding CaCl₂, HPLC of Formula: 23616-79-7, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2021), 421(Part_2), 127815, database is CAplus.

Seeking effective synthesis strategy of adsorbents with di-selective adsorption ability to remove dyes in wastewater is of great significance for solving the increasing environmental problems. Hence, three deep eutectic solvents (DESs) were synthesized and polymerized on the surface of magnetic (Fe3O4) polydopamine (MPDA), in which DES acted as both stabilizer and surface modifier for PDA coating. The fabricated nanoparticles (named as MPDA-PDES) were used as adsorbents for selective adsorption of binary dyes solution Langmuir and Dubinin-Radushkevich isotherm models were suitable to describe adsorption process of malachite green (MG) and sunset yellow FCF (SY) on MPDA-PDES1, resp., indicated that the adsorption of MG was monolayer uptake, and that of SY was phys. adsorption. The effect of solution pH and ionic strength suggested that electrostatic interaction was mainly adsorption driving force. Interestingly, the addition of CaCl₂ in adsorption system realized dynamic transformation from selective adsorption of MG by MPDA-PDES1 to selective adsorption of SY. And selectivity factor reduced from 37.57 to 0.30. MPDA-PDES1 adsorbent possessed excellent anti-interference ability, regeneration and reusability, can be continuously reused six times and adsorption capacity remained basically unchanged. The adsorption of MG-SY from synthetic wastewater manifested that MPDA-PDES1 had unlimited potential for selective removal of target dyes in actual wastewater. Mechanism exploration revealed that MPDA stabilized by DES containing long-chain alkyl groups exhibited better selective adsorption capacity for cationic dyes in binary dyes solutions This was due to the synergistic effect of electrostatic interaction, hydrophobic interaction, hydrogen bonding and π-π stacking between MPDA-PDES1 and dyes. Therefore, proposed DES-based PDA modification strategy improved the stability and reusability of PDA materials, and achieved outstanding selective adsorption ability because of tailorability of DES structure, which provided new ideas for design and synthesis of high-efficiency adsorbents.

Chen, Jing published the artcileA novel”turn-off”fluorescence assay based on acid-copper nanoclusters in deep eutectic solvent micelles for co-aggregation inducing fluorescence enhancement and its application, Safety of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Talanta (2021), 223(Part_1), 121731, database is CAplus and MEDLINE.

As mixtures, deep eutectic solvent (DES) is designability. By adjusting the long alkyl chain hydrogen bond acceptors (HBAs) or hydrogen bond donors (HBDs), the DES displays surfactant characteristics and can form micelles. Hence, a novel, simple, facile and green natural organic acids capped copper nanoclusters (Aci-CuNCs) was synthesized and the spectrum behavior of Aci-CuNCs in DES micelles was researched. It was found that the surfactant-like DES can form micellar co-aggregation with Aci-CuNCs, resulting in the fluorescence (FL) intensive of Aci-CuNCs increase. Corresponding performance of spectral properties of Aci-CuNCs in DES medium were systematically studied by fourier transform IR spectrometer, 3D FL spectroscopy, FL emission/excitation spectra, UV absorption spectroscopy. In the mechanism exploration part, on the one hand, the existence of micellar co-aggregation was confirmed by the conductivity, the mass effect of DES, dynamic light scattering and transmission electron microscopy. On the other hand, the influence of different kinds of DESs (types of HBAs/HBDs, molar ratio) and some possible factors (ionic strength and temperature) were discussed in detail to investigate the main driving forces for the formation of micellar co-aggregates. The results of mechanism exploration prove that the long alkyl chain of DES is amphiphilic which can form micellar co-aggregation with Aci-CuNCs through hydrogen bonding. The DES micelle provides Aci-CuNCs with a relatively stable and closed micro-environment which can effectively prevent collisions with water mols. and weakening of fluorescence intensity. On the basic of the above research, a “turn-off” fluorimetric method based on Aci-CuNCs in DES medium was applied for the determination of Fe³⁺. Under the optimum conditions, the assay worked in the Fe³⁺ concentration ranges from 1 to -20μM and had a detection limit of 0.0374μM. Method validation study illustrates the proposed system can provide a good accuracy, repeatability and stability conditions. Furthermore, the real sample anal. result demonstrates that no obvious matrix effect is found. As a consequence, the FL assays (Aci-CuNCs-based DES) composed of natural organic acid capped CuNCs and green solvent DES provides a simple, gentle and environmentally friendly method for the detection of iron ions.
