A general method for the synthesis of structurally diverse quinoxalines and pyrido-pyrazine derivatives using camphor sulfonic acid as an efficient organo-catalyst at room temperature

A mild, convenient, eco-friendly, general and practical approach has been developed for the synthesis of a series of structurally diverse quinoxaline derivatives via the condensation reactions of various 1,2-diaminobenzene derivatives and 1,2-dicarbonyls such as phenanthrene-9,10-dione, acenaphthylene-1,2-dione or benzil using a catalytic amount of camphor sulfonic acid as an efficient, commercially available, low cost, organo-catalyst in aqueous ethanol at room temperature.

High and selective capture of low-concentration CO2 with an anion-functionalized ultramicroporous metal-organic framework

CO(2)capture, especially under low-pressure range, is of significance to maintain long-duration human operation in confined spaces and decrease the CO(2)corrosion and freezing effect for the liquefaction of natural gas. Herein, we for the first time report a novel anion-functionalized ZU-16-Co (TIFSIX-3-Co, TIFSIX=hexafluorotitanate (TiF62-), 3=pyrazine), which exhibits one-dimensional pore channels decorated by abundant F atoms, for efficient CO(2)capture at a concentration around 400-10,000 ppm. Among its isostructural MFSIX-3 (M=Si, Ti, Ge) family materials, ZU-16-Co with fine-tuned pore size of 3.62 A exhibits the highest CO(2)uptake at 0.01 bar (10,000 ppm) and 1 bar (2.63 and 2.87 mmol g(-), respectively). The high CO(2)capture ability of ZU-16-Co originates from the fine-tuned pore dimensions with strong FMIDLINE HORIZONTAL ELLIPSISC=O host-guest interactions and relatively large pore volumes coming from its longer coordinated Ti-F-Co distance (3.9 A) incdirection. The excellent carbon trapping performance was further verified by dynamic breakthrough tests for CO2/N-2(1/99 and 15/85) and CO2/CH4(50/50) mixtures. The adsorption and separation performances, resulting from the fine-tuned pore system with periodic arrays of exposed functionalities, demonstrate that ultramicroporous ZU-16-Co can be a promising adsorbent for low-concentration carbon capture.

Synthesis, structure and photoluminescence properties of three copper(i) iodide based inorganic-organic hybrid structures with pyrazine derivatives

By using pyrazine derivatives, three different types of copper(i) iodide based inorganic-organic hybrid structures, 1D-CuI(2-mo-pz) (1, 2-mo-pz = 2-methoxy-pyrazine), 2D-CuI(2,3-dm-pz)(0.5)(2, 2,3-dm-pz = 2,3-dimethyl-pyrazine), and 2D-Cu2I2(2,5-dm-pz)(2)(3, 2,5-dm-pz = 2,5-dimethyl-pyrazine), have been obtained by using a slow-diffusion method. Single crystal and powder X-ray diffraction analyses reveal that these hybrid structures are a one-dimensional (1D) staircase chain based structure, two-dimensional (2D) staircase-chain based structure, and 2D rhomboid dimer based structure, respectively. All of the three compounds show photoluminescence, with the internal quantum yield (IQY) as high as 88.2% for1. This work provides evidence that for this type of hybrid materials, the structure of the inorganic module could be determined by the selection of the organic ligands and that the substituted group on the organic ligands can influence the luminescence efficiency of the hybrid structures.

Surface-enhanced Raman scattering of M-2-pyrazine-M-2 (M = Cu, Ag, Au): Analysis by natural perturbation orbitals and density functional theory functional dependence

Here, we propose a new method to analyze various electronic properties of molecules based on natural perturbation orbitals (NPOs). We applied the proposed method to chemical enhancement of the surface-enhanced Raman scattering (SERS) intensity of M-2-pyrazine-M-2 (M = Cu, Ag, Au) complexes. The SERS intensity can be effectively decomposed into the contributions of four NPO pairs (1 sigma-1 sigma*, 2 sigma-2 sigma*, 1 pi-1 pi*, and 2 pi-2 pi*), so NPO analysis makes the SERS intensity much easier to understand than by conventional canonical molecular orbitals. Moreover, we analyzed the dependence of the density functional theory functional on the SERS intensity. For the Ag-2-pyrazine-Ag-2 complex, the BP86 functional overestimates the Raman intensity by about 23 times compared with coupled-cluster singles and doubles level of theory, while the CAM-B3LYP functional gives moderately accurate values. This overestimation arises from the inaccuracy of the energy derivative along the normal vibrational mode.

Terpolymer acceptors based on bithiophene imide for all-polymer solar cells

In order to improve light absorption and promote n-type performance, random copolymerization strategy was employed to afford a series of random terpolymer acceptors with acceptor1-acceptor2-acceptor3 (A(1)-A(2)-A(3)) type backbone. The polymers were synthesized from distannylated electron-deficient bithiophene imide monomer with various electron-deficient dibrominated co-monomers using the typical palladium-catalyzed Stille coupling condensation polymerization. Compared with their parent polymers, these A(1)-A(2)-A(3) type terpolymer acceptors, particularly the dihexylthieno[3,4-b]pyrazine based terpolymer PBTP, can exhibit good miscibility, appropriate polymer crystallinity, and improved absorption in the long-wavelength region due to the incorporation of a third strong electron-withdrawing acceptor moiety thieno[3,4-b]pyrazine. Benefitting from the noncovalent S center dot center dot center dot N interactions, PBTP possessed a planar skeleton and achieved the highest power conversion efficiency (PCE) of 7.35% in the polymer series when serving as the acceptor material in all-polymer solar cells. These results indicate that the A(1)-A(2)-A(3) type terpolymer acceptors should be promising candidates for developing high-performance all-polymer solar cells.

A convenient synthesis, reactions and biological evaluation of novel pyrazolo[3,4-b]selenolo[3,2-e]pyrazine heterocycles as potential anticancer and antimicrobial agents

A novel series of 5-amino-6-substituted-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]selenolo[3,2-e]pyrazines (3a-e) was synthesized by the reaction of the chloro pyrazolo[3,4-b]pyrazine carbonitrile1with selenium element in the presence of sodium borohydride and ethanol, followed by the reaction with alpha-halo alkylating agents to produce the selanyl-alkylated derivatives2a-e. The latter compounds underwentThorpe-Zieglercyclization upon heating with ethanolic sodium ethoxide solution to afford the target selenolopyrazolopyrazine compounds. The 5-amino-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]selenolo[3,2-e]pyrazine-6-carboxamide (3b) was used as a versatile precursor for synthesis of new heterocyclic fused to the pyrazoloselenolopyrazine moiety namely: pyrimidine and imidazopyrimidine. Assignment of the chemical structures for the newly synthesized compounds was confirmed on the bases of elemental and spectral techniques including FT-IR,H-1 NMR,C-13 NMR, and mass spectra. Furthermore, certain compounds were screened for their antimicrobial activity which revealed remarkable activities against various pathogenic strains of bacteria and fungi.

Accelerated Green Process of 2,5-Dimethylpyrazine Production from Glucose by Genetically Modified Escherichia coli

2,5-Dimethylpyrazine (2,5-DMP) is an indispensable additive for flavoring in the food industry and an important substrate for producing hypoglycemic and antilipolytic drugs. However, 2,5-DMP is produced by chemical synthesis in industry. Herein, a green strategy to produce 2,5-DMP has been reported for the first time. To do this, we rewrote the de novo 2,5-DMP biosynthesis pathway and substrate transmembrane transport in an L-threonine high-yielding strain to promote highly efficient 2,5-DMP production from glucose by submerged fermentation. The final strain T6-47-7 could produce 1.43 +/- 0.07 g/L of 2,5-DMP with a carbon yield of 6.78% and productivity of 0.715 g/(L.d) in shake-flask fermentation using a phase-wise manner of hypoxia-inducible expression. The design-based strategy for constructing the 2,5-DMP high-yielding strain reported here could serve as a general concept for breeding high-yielding strains that produce some other type of alkylpyrazine.

Solution of the Inverse Problem for a Complex Vibronic Analogue of the Fermi Resonance on the Basis of Plane Jacobi Rotations

Based on algebraic methods, an exact solution is found to the inverse problem for a complex vibronic analogue of the Fermi resonance, which consists in determining from the spectral data for the observed conglomerate of lines (energies E-k and transition intensities I-k, k = 1, 2, horizontal ellipsis , n; n > 2) the energies of the dark states, A(m), and the matrix elements B-m of their coupling with the bright state. In the first part of the algorithm, using plane Jacobi rotations, an orthogonal similarity transformation matrix X is found, the first row of which is subject to the condition (X-1k)(2) = I-k on its elements, since only one unperturbed state is bright. In the second part, the quantities A(m) and B-m are obtained from the solution of the eigenvalue problem for the block of dark states of the matrix Xdiag({E-k})X-1.
