摘要：
A bidentate directing group-assisted Ni-catalyzed three component 1,2-carbosulfenylation of unactivated alkenes with aryl/alkenylboronic acids and disulfide electrophiles is reported. The reaction affords the desired products with high levels of chemo- and regioselectivity. A wide range of aryl groups and sulfur moieties can be simultaneously installed in both internal and terminal homoallylic amines with excellent functional group tolerance. Notably, the alkene substrates with a chiral center at the α-position furnish α,γ-dibranched thiolamines with high diastereoselectivity and enantioselectivity that would otherwise be difficult to synthesize. The generality and scalability could make this method attractive for preparing complex organosulfur compounds.

摘要：
Two new cobalt(II) coordination complexes [Co(Phtpy)(HBTC)(0.5)](n)center dot nH(2)O (I) and [Co(Meophtpy)(HBTC)(0.5)](n)center dot nH(2)O (II) (Phtpy = 4'-(4-phenyl)-3,2':6',3''-terpyridine, Meophtpy = 4'-(4-methoxyphenyl)-3,2':6',3''-terpyridine,H3BTC = trimesic acid) were synthesized under solvothermal conditions. The structures of complexes I, II have been characterized by elemental analysis, FT-IR, TG analysis, PXRD and single crystal X-ray diffraction techniques (CCDC nos. 2123289 (I) and 2123290 (II)). For complex I, a two-dimensional (2D) layered structure is formed parallel to the bc plane and the adjacent layers are connected by Phtpy ligand along a direction to form a three-dimensional (3D) structure. It is represented as 2-nodal (3, 5)-connected {4.6.8}{4.6(6).8(3)} by Schlafli symbol. For complex II, one-dimensional (1D) ladder chains along two almost perpendicular directions are formed and these chains are connected by Meophtpy ligands to form a 3D structure. It is represented as 2-nodal (3, 5)-connected {4(2).6(5).8(3)}{4(2).6} by Schlafli symbol. In both complexes, dominant antiferromagnetic interactions between Co(II) ions were observed.

摘要：
Eight new diorganotin(IV) complexes (1a-2d), namely {[X-C6H4(O)C=N-N=C(Me)COO]R2Sn(CH3OH)}(n) (1a, 2a), {[X-C6H4(O)C=N-N=C(Me)COO]R2Sn(CH3OH)}(2) (1b, 1c, 1d, 2b), and {[X-C6H4(O)C=N-N=C(Me)COO]R2Sn}(2) (2c, 2d) (X = H-, p-Me-, p-OH-, p-NO2-; R = o-Cl-C6H4CH2- or o-Me-C6H4CH2-), have been synthesized by microwave "one-pot" reaction with arylformylhydrazine, pyruvic acid, and the corresponding R2SnCl2. All the complexes have been characterized by FT-IR (Fourier transform infrared spectroscopy), multinuclear NMR (H-1, C-13, and Sn-119 nuclear magnetic resonance spectroscopies), HRMS (high-resolution mass spectroscopy) and single-crystal X-ray structural analysis. The antiproliferative activity of all complexes was tested against the cancer cell lines NCI-H460, MCF-7 and HepG2. The diorganotin complex 1c has been shown to be more potent antitumor agents against HepG2 than other complexes and cisplatin. Flow cytometry analysis observation demonstrated that complex 1c mediated cell apoptosis of HepG2 cells and arrested cell cycle in the S phase. The single cell gel electrophoreses assay results show that the 1c induce DNA damage. The DNA binding activities of the 1c were studied by UV-visible absorption spectrometry, fluorescence competitive, circular dichroism measurements, and molecular docking, results shown 1c can be well embedded in the groove and cleave DNA.

摘要：
A room temperature Mg(OtBu)2-catalyzed C(sp3)–H oxidation of α-azido arylethanones to straightforwardly produce primary α-ketoamides is presented. By utilizing TBHP as the oxidant and carbonyl oxygen source, this method allows the oxidation of dual methylene C–H bonds α to the carbonyl group for the synthesis of various primary α-ketoamides in moderate to good yields. This method is applicable to one pot oxidative coupling of α-bromoarylethanones with sodium azide leading to primary α-ketoamides.

摘要：
Here we report a facile and cost-effective preparation of nickel nanoparticle S/Nitrogen-carbon nanohybrid (Ni NPS/N-C) based on formamide condensation and carbonization, used for highly sensitive and selective electrochemical determination of tryptophan (Trp) in practical samples. The crystallographic phase, surface morphology, elemental distribution, and chemical state of the Ni NPS/N-C nanohybrid were analyzed by XRD, SEM, TEM, EDS, XPS, FTIR, TGA and Raman spectra. The results show that high content of Ni NPs (6.62 wt%) were distributed in the nanohybrid, and a large number of bamboo-like nanotubes were formed during pyrolysis, which dramatically increases the specific surface area, and remarkably promotes the electrical conductivity as well as the catalytic activity of the nanohybrid. The electrochemical behavior of Trp was investigated on the nanohybrid modified carbon paste electrode (Ni NPS/N-C/CPE) and the measurement parameters were optimized. As expected, the modified electrode can remarkably enhance the electrochemical oxidation signal of Trp. Under the optimal experimental conditions, a linear relationship in the range of 0.01-20 mu M and 20-80 mu M for Trp was established with detection limit of 5.7 nM (S/N = 3). Finally, the proposed sensor was practically applied by evaluation and determination of Trp from various sourcing samples including human serum and pharmaceutical samples.

摘要：
We rationally design and construct a heterostructured hybrid with reduced graphene oxide served as a platform to in-situ grow N-doped bamboo-like carbon nanotubes encapsulating bimetallic Co-Fe sulfide nanoparticles through a two-stage pyrolysis succeeded by an evaporating sulfurization process (denoted as CoxFe1-xS2@N-CNTs/rGO). By tuning the Co/Fe ratio, the optimal Co0.6Fe0.4S2@N-CNTs/rGO exhibits a remarkable oxygen evolution reaction (OER) performance in 1.0 M KOH, in which the overpotential at 10 mA cm(-2) and Tafel slope are recorded as 248 mV (vs. RHE) and 58.3 mV dec(-1), respectively, outmaneuvring commercial RuO2 and most Co/Fe sulfide-based catalysts in recent peer reports. Comprehensive experiment results unravel that the outstanding OER electrocatalytic performance owes to the reinforced synergy between CoS2 and FeS2, the heterostructures constituted by partial CoS2 and FeS2, the confining effect of N-CNTs/rGO for CoS2 and FeS2 nanoparticles, and the high conductivity and large surface of N-CNTs/rGO.

摘要：
Multiblock copolymer brushes have broad application in thermoplastic elastomers, drug delivery, porous materials, and nanolithography due to their unique structure and properties. In this research, a novel multiblock copolymer brush (PHEA-g-PEG)(x)-co- (PEG(23))(y) was synthesized by combining the efficient double strain-promoted azide-alkyne cycloaddition (DSPAAC) and copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reactions. The gel permeation chromatography (GPC), proton nuclear magnetic resonance spectrometer (H-1 NMR), Fourier transform infrared spectroscopy (FT-IR), and atomic force microscopy (AFM) were used to characterize the prepared polymers. The results demonstrated that the novel multiblock copolymer brush was successfully prepared. The mole ratio was 1/0.84 between block PHEA-g-PEG and block PEG(23), and the grafting density was 100%. The AFM image showed the morphologies of cylinder, sphere, and beads on a string owning to the random distribution of PHEA-g-PEG and PEG.

摘要：
A Fe-based metal-organic framework, [Fe（INAIP）（DMF）]n·0.5nDMF（1）, has been synthesized by the reaction of 5-（isonicotinamido）isophthalic acid（H2INAIP） with FeSO4·7H2O under DMF reaction solvent. Single-crystal X-ray diffraction analysis indicates that complex 1 displays a two-fold interpenetrated three-dimensional（3D） framework with sra topology. The TG, magnetic and adsorption properties of the complex were also studied.

摘要：
A new europium(III) complex Eu(C20H14O3N)(3) (2,2'-bipy)(H2O)center dot H2O has been synthesized with 2-diphenylanine carbonyl benzoic acid and 2,2'-bipyridine as ligands. Crystal data for the complex are as follows: triclinic, space group P (1) over bar, a = 11.3334(5), b = 16.0883(7), c = 17.0116(8) angstrom, alpha = 70.411(4)degrees, beta= 82.435(4)degrees, gamma = 85.095(4)degrees, V = 2894.0(2) angstrom(3) , D-c = 1.484 g/cm(3) , Z = 2, mu = 1.15 mm(-1) , F(000) = 1320 and the final R= 0.0447 and wR = 0.0578. The Eu(III) ion is coordinated by nine atoms to give a monocapped square antiprism coordination geometry. The complex shows two intense fluorescence emission bands arising from the transitions of Eu3+ : D-5(0) -> F-7(1) (592 nm) and D-5(0) -> F-7(2) (616 nm), respectively. Also reported is the magnetic property of the complex. The complex exhibits antiferromagnetism in the temperature range of 300 similar to 2 K.
