Abstract ：
Through the method of solvent-free confined encapsulation, , dibromo-p-diphenyl- p-diphenyl and 4,4 '-bipyridine , 4 '-bipyridine were adsorbed into the UiO-67-67 material, , and then in situ polymerized into the polymer ionic liquid PBpy-Br.-Br. The composite PBpy-Br@UiO-67-Br@UiO-67 contains three kinds of active centers: : Br-, - , Zr-OH/Zr-OH2-OH/Zr-OH2 and N heterocyclic. The structure was characterized by X-ray-ray diffraction(XRD), ( XRD ), Fourier transform infrared(FTIR) ( FTIR ) spectroscopy, , scanning electron microscopy(SEM), ( SEM ), 13 C nuclear magnetic resonance spectrometry(13C ( 13 C NMR), ), Brunauer-Emmett-Teller(BET)-Emmett-Teller ( BET ) analysis and thermogravimetric analysis(TGA). ( TGA ) . The composite was applied to catalyze the cycloaddition reaction of CO2 and epichlorohydrin. On the basis of single factor experiments, , the optimal reaction conditions determined by response surface optimization were 100 degrees C, , p CO2 =0.1 MPa, , PBpy-Br@UiO-67-Br@UiO-67 mass fraction of 0.22% and 22 h. Under the optimum reaction conditions, , the yield of cyclochlorocarbonate reached 99.6%, , and the conversion decreased by only 2.3% after 5 cycles. When the composite was used to catalyze other epoxides, , a conversion of over 50% was obtained. PBpy-Br@UiO-67-Br@UiO-67 has milder reaction conditions and higher catalytic efficiency, , which provides a new catalytic system for CO2 2 fixation and conversion.

Abstract ：
Incorporation of ionic liquids into metal-organic frameworks (MOFs) offers a new platform to construct heterogeneous bifunctional catalytic systems for the chemical capture and conversion of CO2 with epoxides. Herein, an imidazolium-based ionic liquid decorated UiO-66 type MOF (P3[BCMIm]Br@UiO-66) was successfully constructed via solvothermal assembly of the carboxyl-functionalized imidazolium ionic liquid ligand, terephthalic acid ligand and Zr(iv) ions. It exhibits the highest catalytic activity upon the cycloaddition of CO2 (98.2% conversion of propylene oxide and 99% selectivity to propylene carbonate) under optimized conditions (2.2 Mpa CO2, 1.0 wt%, 110 degrees C, reaction time 2 h). Notably, P3[BCMIm]Br@UiO-66 outperformed the original UiO-66 materials and [BCMIm]Br. P3[BCMIm]Br@UiO-66 retained its good catalytic performance for up to five recycling runs with only a little loss in catalytic activity. Furthermore, several additional coupling reactions were investigated with other epoxides as substrates.

Abstract ：
The tandem synthesis of 2-trifluoromethylthio-(seleno)-substituted benzofurans using palladium-catalyzed conditions is reported. Trifluoromethylthio(seleno)lation of 2-(2,2-dibromovinyl)phenols with (bpy)CuSCF3 or [(bpy)-CuSeCF3](2) furnishes several 2-trifluoromethylthio(seleno)-lated benzofurans in acceptable to good yield. Mechanistic investigations were performed to elucidate the reaction pathway, which was involved in the formation of a 2-bromobenzofuran species. The scope of this protocol was further extended to the preparation of 2-trifluoromethylthio(seleno)lated benzothiophenes and indoles.

Abstract ：
A copper-mediated difluoromethylenation of o-bromophenols with trifluoromethanethiolate is described. This one-pot protocol proceeds through an intermolecular addition of S=CF2 (resulting from the decomposition of trifluoromethanethiolate) to o-bromophenols followed by intramolecular C-S coupling to form 2,2-difluoro-1,3-benzoxathioles. This method is compatible with a broad range of substrates and enables the late-stage difluoromethylenation of several functionally dense druglike o-bromophenols.

Abstract ：
A mild and efficient trifluoromethylselenolation of acid chlorides with [(bpy)Cu(SeCF3)](2) (1) in the presence of a catalytic amount of metallic iron powder is described. Easily available benzoyl chloride derivatives and alkyl acid chlorides are smoothly converted into the corresponding Se-trifluoromethyl esters in good to excellent yields. This simple transformation demonstrates a broad substrate scope with respect to acid chlorides, and is amenable to being carried out on gram scales. (C) 2016 Elsevier B.V. All rights reserved.
