The 1,8-naphthyridine-functionalized N-heterocyclic carbene 1-benzyl-3-(5,7-dimethyl-1,8-naphthyrid-2-yl)imidazol-2-yl-idene (BIN) has been successfully coordinated to Pd(II), W(0), Rh(l), and Ir(III), exhibiting its diverse binding modes. Reaction of BIN center dot HBr with Ag2O, followed by transmetalation with PdCl2(COD)(2) provides a cis complex PdCl2(kC(2)-BIN)(2) (1). Treatment of BIN center dot HBr with W(CO)(4)(pipeddine)(2) in acetonitrile affords a chelate complex W(CO)(4)(k(2)C(2),N-1′-BIN) (2). Reaction of {RhCl(COD)}(2) with KOBu and subsequent treatment with BIN center dot HBr in 1:2 and 1:1 ratio results in the mono and dinuclear complexes [Rh(COD)Br(KC2-BIN)] (3) and [{Rh(COD)Br)(2)(KN8′:C-K(2)-BIN)] (4), respectively. In complex 3, the Rh(COD)Br unit is coordinated to the carbene center, whereas an additional Rh(COD)Br unit is attached to naphthyridine nitrogen in complex 4 in an anti arrangement. Under identical reaction condition, a novel Ir(III) complex [Ir((KC2)-C-2,N-1′-BIN)((KC3)-C-2′,C-2-BIN)(H2O)Br]Br (5) has been synthesized. Complex 5 is proved to be catalytically active in hydrogen transfer reaction from PrOH. All complexes have been characterized by spectroscopic methods and X-ray crystallography.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Grandl, Markus, once mentioned the application of 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, molecular formula is C7H6N2O4. Now introduce a scientific discovery about this category, Quality Control of 4-Amino-3-nitrobenzoic acid.

A series of new pi-conjugated N -> B-ladder boranes has been prepared in high yield by two-fold hydroboration of bifunctional quaterpyridine-, pyrimidine-, and 1,5-naphthyridine-based precursors with 9H-BBN and Piers’ borane ((C6F5)(2)BH). The structures of several ladder-boranes have been confirmed by X-ray crystallography, and their optical and electrochemical properties have been characterized, and complemented by DFT calculations. The electronic structure of the individual ladder boranes, as well as differences in the optical properties that originate from the chemical structure of the boryl-side-chains, are discussed. The results consistently show that, compared to the precursors, the optical gaps of the ladder boranes are significantly reduced, and the electron affinities are strongly increased to between -3.4 and -4.0 eV. Further investigations of chemically and electrochemically reduced species indicate that excess electrons in these kinds of systems are effectively delocalized throughout the conjugated systems.

An exceptionally strong quadruply hydrogen-bonded complex is formed between 2,7-diamido-1,8-naphthyridine 3 (DAN) and the butylurea of guanosine 6 (UG) in chloroform. The UG unit can be prepared in four steps from guanosine on a 10 g scale in excellent yields without chromatographic purification. The association constant (K-assoc approximate to 5 x 10(7) m(-1)) for the UG(.)DAN complex determined by fluorescence energy transfer from the naphthyridine unit of 3 to coumarin 343 covalently linked UG (18) is among the highest reported for a neutral DNA base-pair analogue. The weak self-association of DAN (K-dimer < 10 m(-1)) and UG (K-dimer ca. 200-300 m(-1)) means that the UG-DAN complex forms with unparalleled fidelity. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

Five new dinuclear palladium(II) complexes with general formula, [{Pt(L)Cl}(2)(mu-1,5-nphe)](NO3)(2)(L is ethylenediamine (en), (+/-)-1,2-propylenediamine (1,2-pn),trans-(+/-)-1,2-diaminocyclohexane (dach), 1,3-propylenediamine (1,3-pd), (+/-)-1,3-pentanediamine (1,3-pnd) and 1,5-nphe is bridging 1,5-naphthyridine ligand) were synthesised and spectroscopically characterized.In vitrocytotoxic activity of these complexes was evaluated against mouse mammary carcinoma (4T1), colon (CT26), lung cancer cells (LLC1) and melanoma (B16-F10) as well as human lung adenocarcinoma (A549), mammary carcinoma (MDA-MB-468), and colon cancer (HCT 116). The investigated complexes reduced viability of tumor cells in dose dependent manner. Dinuclear Pd(II) complexes act less cytotoxic toward tumor cells, compare to cisplatin, but also have greater selectivity toward mesenchymal stem cells. The potential mechanism of cell death of tumor cells treated with palladium(II) 1,5-naphthyridine dinuclear complexes is enhanced apoptosis, facilitated by down-regulation of anti-apoptotic Bcl-2 and up-regulation of pro-apoptotic Caspase-3.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

Application of 1588-83-6, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, SMILES is C1=C([N+]([O-])=O)C(=CC=C1C(=O)O)N, belongs to naphthyridine compound.

The Fe3O4/ZnO/MWCNTs magnetic nanocomposites as a high performance organomettalic catalyst was employed for the preparation of naphthyridine derivatives in high yields via five component reaction of isoquinoline, dialkyl acetylenedicarboxylates or propiolates, alpha-haloketones, triphenyphophine and ammonium acetate in aqueous media at ambient temperature. The Fe3O4/ZnO/MWCNTs MNCs were synthesized using ionic liquid [OMIM]Br as a stabilizer and soft template. As well Fe3O4/ZnO/MWCNTs MNCs show a good improvement in the yield of the product and showed significant reusable ability. Due to having isoquinoline core, we investigate antioxidant property of some synthesized compounds by diphenyl-picrylhydrazine (DPPH) radical trapping and power of ferric reduction experiment. Furthermore, the disk diffusion test on Gram positive and negative bacteria are utilized for investigation of antimicrobial activity of some naphthyridines. The achieved outcomes of this experiment demonstrate that these synthesized compounds could prevent from growth of bacteria. Short time of reaction, high yields of product, easy separation of catalyst and products are some benefits of this process.
