The limitations of arene C-H functionalization of aryl sulfonamides containing strongly coordinating Nheterocycles were overcome using a Rh(III) catalyst. The site-selectivity of C-H carbenoid functionalization at the ortho position relative to either the sulfonamide or N-heterocycle directing groups was elegantly switched using solvents of different polarities and different additive concentrations. Importantly, sulfonamide-group-directed ortho-C-H carbenoid functionalization tolerated strongly coordinating N-heterocycles, including pyridine, pyrrole, thiazole, pyrimidine, and pyrazine. Density functional theory (DFT) calculations were performed to rationalize the reaction mechanisms and the influence of reaction polarity.

A sequential and general strategy has been successfully developed for the synthesis of spiropyrazolone scaffolds. This intriguing transformation of the asymmetric multicomponent catalysis process was realized with the combination of Michael addition/chlorination/nucleophilic substitution in a one-pot sequence, giving rise to a series of spiropyrazolones with fully substituted cyclopropanes and spiro-dihydrobenzofurans containing continuous stereogenic centers in good yields with excellent stereoselectivities.

The changes in spectra and intensities of the streamwise component of turbulent velocity are calculated in the inflow of a turbine rotor. The flow is initially calculated in the limit when the turbulence is of small scale compared with the rotor diameter. Rapid distortion theory (RDT), Batchelor & Proudman (Q. J. Mech. Appl. Maths, vol. 7 (1), 1954, pp. 83-103) (BP), for small-scale turbulence is combined with the effect of the fluctuating potential flow field on the turbulence caused by the direct interaction of the incident turbulence with the rotor as a sheet of resistance. A second computation is then carried out for turbulence of larger length scale. The results of the calculations are compared with velocity measurements in the inflow of both a commercial wind turbine and a tidal turbine rotor.

Here in, the effects of FeSiAl particle size on the dielectric and microwave absorption properties of FeSiAl/Al2O3 composites were studied. FeSiAl/Al2O3 composites containing 18-25 mu m, 25-48 mu m, and 48-75 mu m FeSiAl particles were prepared by hot-pressed sintering based on uniformly mixed FeSiAl and Al2O3 powders. Results show that the real permittivity and the imaginary permittivity are significantly promoted with increasing FeSiAl particle size, which is ascribed to the enhanced interfacial polarization and conductance loss. In addition, the favorable matching impedance and suitable attenuation coefficient enabled the composite containing 25-48 mu m FeSiAl powder to show a minimum reflection loss of -34.4 dB at 11.7 GHz and an effective absorption bandwidth (<-10 dB) of 1.4 GHz in 11.0-12.4 GHz, when the thickness is 1.1 mm. By adjusting the thickness to 1.4 mm, the effective absorption bandwidth of the composite reaches a maximum value of 2.0 GHz in the 8.3-10.3 GHz range, indicating tunable, strong, and highly efficient microwave absorption performance. COA of Formula: C12H12N2O3. Bye, fridends, I hope you can learn more about C12H12N2O3, If you have any questions, you can browse other blog as well. See you lster.

Michael addition of 3-tert-butylpyrazole (1) or 3,5-dimethylpyrazole (2) to acrylamide afforded the pyrazolylpropanamide-type ligands 3-(3-tert-pyrazol-1-yl)propanamide (3, = (t)BuPPA) and 3-(3,5-dimethylpyrazol-1-yl)propanamide (4, = Me(2)PPA), respectively, in high isolated yields (3: 80%, 4: 76%). Reactions of 4 with selected first-row transition-metal chlorides (MnCl2 center dot 4H(2)O, CoCl2 center dot 6H(2)O, ZnCl2, CuCl2 center dot 2H(2)O) afforded the new complexes MnCl2(Me(2)PPA)(2) (5), [MCl2(Me(2)PPA)](2) (M = Co (6), Zn (7)), and CuCl2(Me(2)PPA)(2)center dot 2H(2)O (8). Ligand 3 and all four new complexes 58 have been structurally characterized though single-crystal X-ray diffraction. Surprisingly, the crystal structure determinations revealed three different coordination modes for the pyrazole-based ligand in these complexes. Seven-membered kappa N,kappa O-chelate rings are present in the manganese(II) complex 5. In contrast, kappa N: kappa O-bridging coordination of Me(2)PPA in compounds 6 and 7 leads to formation of dimers comprising 14-membered ring systems. Furthermore, unusual kappa N-monodentate coordination of Me2PPA has been found in the structure of the hydrated copper(II) complex Cu(Me(2)PPA)(2)Cl-2 center dot 2H(2)O (8). In the crystalline state, all four complexes 58 form one- or two-dimensional supramolecular structures assembled through different types of hydrogen bonding. (C) 2019 Elsevier Ltd.

Linear alkanes are essential building blocks for natural and artificial assemblies in water. As compared with typical, linear alkane-based micelles and recent aromatic micelles, we herein develop a cycloalkane-based micelle, consisting of bent amphiphiles with two cyclohexyl frameworks. This uncommon type of micelle, with a spherical core diameter of similar to 2nm, forms in water in a spontaneous and quantitative manner. The cycloalkane-based, hydrophobic cavity displays peculiar host abilities as follows: (i) highly efficient uptake of sterically demanding Zn(II)-tetraphenylporphyrin and rubrene dyes, (ii) selective uptake of substituted Cu(II)-phthalocyanines and spherical nanocarbons, and (iii) uptake-induced solution-state emission of [Au(I)-dimethylpyrazolate](3) in water. These host functions toward the large metal-complex and other guests studied herein remain unaccomplished by previously reported micelles and supramolecular containers.

A new fumarato bridged Zn(II) coordination polymer viz. catena[mu-fumaratobis(3,5-dimethylpyrazole)zinc(II) trihydrate],{[Zn-2(mu-fum)(2)(Hdmpz)(4)]center dot 3H(2)O}(n) (1) (where, fum = fumarate, Hdmpz = 3,5-dimethylpyrazole) has been synthesized in purely aqueous medium at room temperature. The compound is structurally characterized by single crystal X-ray diffraction, FT-IR, electronic spectroscopy, PXRD and TGA. The zig-zag polymeric chain of 1 self assembles into a 2D supramolecular network via C-H center dot center dot center dot pi, C-H center dot center dot center dot C, N-H-center dot center dot center dot O and C-H center dot center dot center dot O interactions. Particularly relevant in 1, since in addition to the aforementioned non-covalent interactions, the electron rich pi-system of fumarate is involved in energetically significant unconventional pi-pi contacts with the electron poor pi-cloud of Hdmpz, which have been analyzed by DFT calculations and characterized using the non-covalent interaction (NCI) plot index. The strong H-bond agrees well with the MEP analysis since it is established between the H-bond donor involving NH group of Hdmpz and the H-bond acceptor involving O-atom of carboxylate moiety. The compound has been investigated for anticancer activities considering cell cytotoxicity, apoptosis and molecular docking as parameters in Dalton’s lymphoma (DL) malignant cancer cell line and results were compared with cisplatin (reference drug) under the same experimental conditions. Interestingly, negligible cytotoxic effect was observed against normal cells (PBMC) in comparison to the cancer cells (DL). The treatment of the compound caused appearance of apoptotic cells as evident by fluorescence based nuclear morphology study. The in silica study reveals that the compound interacts with the antiapoptotic proteins such as bcl-2, bcl-XL and Mcl-1 which may lead to apoptotic cell death.
