We report the synthesis of quinolines using cyclopropenes and an azidobenziodazolone (ABZ) hypervalent iodine reagent as an azide radical source under visible-light irradiation. Multisubstituted quinoline products were obtained in 34-81% yield. The reaction was most efficient for 3-trifluoromethylcyclopropenes, affording valuable 4-trifluoromethylquinolines. The transformation probably proceeds through the cyclization of an iminyl radical formed by the addition of the azide radical on the cyclopropene double bond, followed by ring-opening and fragmentation.

Photoprocesses in bis(15-crown-5)-1,3-distyrylbenzene (DSB) and its complexes with barium and lead perchloatewere studied in MeCN by absorption, luminescence, and laser kinetic spectroscopy. The triplet DSB molecules are involved in the degradation of electronic excitation energy, together with fluorescence processes. The most efficient intersystem crossing accompanied by a decrease in the DSB fluorescence quantum yield, occurs for the lead perchlorate complex. Using quantum chemistry methods (DFT and TDDFT), the geometry, structure, and transition energies to the S1 state were calculated for trans- and cis-isomers of DSB in the gas phase and with allowance for the solvent and for 1:1 and 2:2 DSB complexes with barium cation in the ground and excited states. The orbital structures of the 2:2 complexes were calculated by ab initio method, and conclusions were drawn about the possibility of [2 + 2]- photocycloaddition reaction.

Nucleophilic aromatic substitution (SNAr) is routinely used to install (19)F(-)and (18)F(-)in aromatic molecules, but is typically limited to electron-deficient arenes due to kinetic barriers associated with C-F bond formation. Here we demonstrate that a polarity-reversed photoredox-catalysed arene deoxyfluorination that operates via cation-radical-accelerated SNAr enables the fluorination of electron-rich arenes with (19)F(-)and (18)F(-)under mild conditions, and thus complements the traditional arene polarity requirements necessary for SNAr-based fluorination. The utility of our radiofluorination strategy is highlighted by short reaction times, compatibility with multiple nucleofuges and high radiofluorination yields, especially that of an important cancer positron emission tomography agent [F-18]5-fluorouracil. Taken together, our fluorination approach enables the development of fluorinated and radiofluorinated compounds that can be difficult to access by classical SNAr strategies, with the potential for use in the synthesis and discovery of positron emission tomography radiopharmaceuticals.

A Cd(II) coordination polymer based on a polytopic compartmental ligand was synthesized, and used as an efficient heterogeneous catalyst for the Knoevenagel reaction between benzaldehyde and malononitrile under mild reaction conditions. The solid catalyst was characterized using single crystal XRD, X-ray powder diffraction, SEM, TGA, UV diffuse reflectance, infrared spectroscopy and elemental analysis. The compound is a two-dimensional (2D) MOF with a grid structure. Topological analysis of the framework revealed that it is a 2,4-connected binodal net. The catalytic activity was tested between various benzaldehydes containing different substituents with malononitrile. The effect of reaction parameters such as solvent, time, reactant ratio and catalyst amount was investigated. Furthermore, the catalyst stability was examined through reusability experiments and it is observed that the catalyst can be recycled at least five times without significant drop in its activity.

The organic ligands with good coordination ability to Eu(III) ion attracted great attention, but the preparation of multifunctional organic ligands with excellent performance and the potential application was still a challenge in the field of rare earth coordination. In this work, a series of Schiff-base ligands and their corresponding Eu(III) complexes were successfully prepared. The ligands L1-4 exhibited typical AIE properties with various fluorescence emissions and high fluorescence quantum yields in an aggregated state. The luminescence intensity and luminescence lifetime of Eu(III) complexes were investigated by comparing different substituents of ligands. Density functional theory (DFT) calculations suggested that the electronegativity of the ligands L1-4 changed with the change of the substituents on the salicylaldehyde, which led to the phenomenon that the ligands exhibited diverse fluorescence emission from green to orange (maximum emission wavelengths were 525 nm, 546 nm 569 nm and 582 nm, respectively). All target Eu(III) complexes exhibited red luminescence of Eu(III) ions, accompanied by outstanding thermal stability and long luminescence lifetime. The effect of various substituent groups on luminescence intensity and luminescence lifetime of complexes was ordered: EuL3(Phen) (NO3)(3) > EuL2(Phen)(NO3)(3) > EuL1(Phen)(NO3)(3) > EuL4(Phen)(NO3)(3). Based on the above results, all ligands and corresponding target Eu(III) complexes had good application prospects in the field of optical materials.

A visible-light-induced oxidative coupling of diselenides with readily available vinylarenes is demonstrated. This benign protocol allows one to access a wide range of alpha-aryl and alpha-alkyl selenomethyl ketones in good yields with excellent functional group compatibility. The distinct advantages of this protocol over all previous methods include the use of a green solvent and air as an oxidant and the lack of a photocatalyst, a base, and an oxidant as well as better green chemistry matrices. Furthermore, the title reaction can be performed with natural sunlight, the most sustainable energy source imaginable. Additionally, the mild reaction conditions, easy operation and suitability for the modification of styrene-functionalized biomolecules make the current reaction system a more attractive method for the synthesis of a variety of medicinal and agrochemical compounds of interest.

A novel oxidative esterification of 1-arylprop-2-en-1-ols with toluene derivatives catalyzed by tetrabutylammonium iodide (TBAI) is reported. The optimization of the reaction conditions illustrates that each of experiment parameters including the catalyst, solvent, and oxidant is significant for present oxidative functionalization. This metal-free protocol has a broad substrate scope including the halogen groups for further functionalization and enriches the reactivity profile of allyl alcohol and toluene derivatives. In addition, this protocol represents a new transformation of allyl alcohol involving C-C bond cleavage and C-O bond forming.

Membrane fouling is a major challenge for long-term oil/water separation. The incomplete degradation of organic pollutants or membrane damage exists in the common methods of membrane regeneration. Herein, a dual-responsive nanofibrous membrane with high water-in-oil emulsion separation efficiency and smart cleaning properties is reported, which shows complete restoration of its original separation performance. The pH-responsive and upper critical solution temperature (UCST)-type thermoresponsive nanofibrous membrane with a micro/nanosphere structure was developed via a one-step-blending electrospinning strategy. The membrane displays high hydrophobicity/oleophilicity at pH 7 and 25 degrees C and hydrophilicity/oleophobicity at pH 3 and 55 degrees C. As a result, it exhibits an ultrahigh permeability of 60528.76 L m(-2) h(-1) bar(-1) and a separation efficiency of 99.5% for water-in-D5 emulsions at room temperature (25 degrees C). Moreover, the contaminated membranes could be easily reclaimed by being rinsed with warm acidic water (pH 3 and 55 degrees C). The membrane maintained high separation performance after being used for multiple cycles, indicating its scalable application for purifying emulsified oil. This study provides a facial method of constructing membranes with multiscale hierarchical structures and a new idea for the design of recyclable oil/water separation membranes.
