A Polypyridyl-Based Layered Complex as Dual-Functional Co-catalyst for Photo-Driven Organic Dyes Degradation and Water Splitting

With the ever-increasing concerns on environmental pollution and energy crisis, it is of great urgency to develop high-performance photocatalyst to eliminate organic pollutants from wastewater and produce hydrogen via water splitting. Herein, a polypyridyl-based mixed covalent Cu-I/II complex with triangular {Cu-3} and rhombic {Cu2Cl4} subunits alternately extended by mixed SCN- and Cl- heterobridges [Cu-4(DNP)(SCN)Cl-4](n) (1) [DNP = 2,6-bis(1,8-naphthyridine-2-yl)pyridine] was solvothermally synthesized and employed as a dual-functional co-photocatalyst. Resulting from a narrowed band-gap of 1.07 eV with suitable redox potential and unsaturated Cu-I/II sites, the complex together with H2O2 can effectively degrade Rhodamine B and methyl orange up to 87.4 and 88.2%, respectively. Meanwhile, the complex mixed with H2PtCl6 can also accelerate the photocatalytic water splitting in the absence of a photosensitizer with the hydrogen production rate of 27.5 mu mol.g(-1).h(-1). These interesting findings may provide informative hints for the design of the multiple responsive photocatalysts.

Methods have been developed for the synthesis of new substituted 7,8,9,10-tetrahydro[1,2,4]triazolo-[3,4-a][2,7]naphthyridines from 3-chloro-1-hydrazino-7-methyl-5,6,7,8-tetrahydro-[2,7]naphthyridine-4-carbonitrile.

The HyperChem 7.5 software was used for quantum mechanical calculations. The geometry optimization, contour maps of highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO) and corresponding binding energy values of molecular and ionic forms of title compound were computed using semi empirical single point PM3 method, in order to understand the binding modes of metal complexes. The stoichiometric studies of complexes determined spectrophotometrically using Job’s continuous variation and mole ratio methods inferred 1:2 ratio in respective systems. The title compound and its metal complexes screened for antibacterial and antifungal properties indicated more pronounced activity of Cu-II complex compared to other compounds. The studies of nuclease activity for the cleavage of PBR322 DNA and MTT assay for in vitro cytotoxic properties showed high activity of Cu-II complex. The interaction studies of metal complexes with CT-DNA investigated by UV-Visible and fluorescence titrations revealed the intercalation mode of binding. Docking studies were also performed to illustrate the binding mode of the title compound with the target site of Thymidine phosphorylase from E. coli (PDB ID: 4EAF) protein.

Iodine-catalyzed synthesis of dibenzo[b,h][1,6]-naphthyridine-11-carboxamides via a domino reaction involving double elimination of hydrogen bromide

An iodine-catalyzed reaction of 2-aminobenzamides and mucobromic acid was described and utilized to synthesize a variety of 6-oxo-5,6-dihydrodibenzo[b,h][1,6] naphthyridine-11-carboxamide derivatives in refluxing THF. As the two bromine atoms in mucobromic acid were found missing in the dibenzo-naphthyridine products, a domino-type reaction mechanism involving a double elimination of hydrogen bromide was proposed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3491-12-1, in my other articles.

CONDENSED ISOQUINOLINES. 37. HETEROCYCLIZATION USING 3-(ARYLAMINO)- AND 3-(HETARYLAMINO)ISOQUINOLIN-1(2H)-ONES

The reaction of 3-NHR-isoquinolin-1(2H)-ones (R = Ar) with aromatic aldehydes in the presence of Me3SiCl or in acetic acid leads to the formation of derivatives of dibenzo[b,f][1,8]naphthyridin-5(6H)-one and benzo[f]isoquino[3,4-b][1,8]naphthyridine-5,9(6H, 7H)-dione. The reaction for R = Het in the presence of Me3SiCl gives derivatives of 5H-pyrido[1′,2′:1,2]pyrimido[4,5-c]isoquinolin-5-one, benzo[f]isoquinoline[3,4-b][1,8]naphthyridine-5,9[6H,7H]-dione, and derivatives of new heterocyclic systems, 5H-pyrazino[1′,2′:1,2]pyrimido[4,5-c]isoquinolin-5-one, 5H-[1,3]thiazolo[3′,2′:1,2]pyrimido-[4,5-disoquinolin-5-one, 5-H-benzo[f]pyrazolo[3,4-b][1,8]naphthyridin-5-one, and isoquino[3,4-b]1,5]naphthyridin-5(6H)-one. The effect of the structure of substituent R and nature of the substituent in the benzaldehydes on the structure of the reaction products was studied.

Synthesis, Characterization and Structure of Tribromo(2-phenyl-1,8-naphthyridine)gold(III)

Neutral tribromo(2-phenyl-1,8-naphthyridine)gold(III), AuBr3(N-N), has been prepared by reaction of KAuBr4 with the ligand in CHCl3/C2H5OH and was characterized by H-1 NMR spectroscopy and X-ray diffraction. The molecular and crystal structure of AuBr3(N-N) center dot 0.5 THF (triclinic, P1, a = 11.314(2), b = 12.350(3), c = 14.628(3) angstrom, alpha = 107.96(3), beta = 98.86(3), gamma = 107.29(3)degrees, Z = 4, 173 K) shows coordination of the N-8 nitrogen atom situated in the unsubstituted pyridine ring to the planar four-coordinate Au-III center. Whereas the AuBr3N best planes and the coordinated naphthyridine rings are not far from orthogonal (omega similar to 105 degrees), the phenyl substituents were found in the crystal with a ca. 22 degrees dihedral angle relative to the naphthyridine plane. Intermolecular Au center dot center dot center dot Br distances close to the sum of the van der Waals radii indicate very weak interactions to form a quasi-dimeric arrangement in the crystal.

Multi-Step Synthesis of Biologically Active Novel N-Benzyl-3,5-Bis(Arylidene)-Piperidin-4-Ones and Some Derived Bicyclic and Tricyclic Ring Systems as Macromolecules

This study reports the synthesis of some new bicyclic and tricyclic heterocyclic macromolecules incorporated pyrano[3,2-c]pyridine, 1,6-naphthyridine, and pyrimidonaphthyridine rings starting from new dienones, N-benzyl-3,5-bis(arylidene)-piperidin-4-ones. The chemistry involved the cyclocondensation of dienones with malononitrile in the presence of piperidine yielded the target 2-aminopyranopyridine-3-carbonitriles. The reaction of dienones with malononitrile or ethyl cyanoacetate in the presence of excess ammonium acetate afforded the corresponding 2-aminonaphthyridines and/or 2-oxonaphthyridine derivatives, respectively, in good yields. The 2,4-disubstituted pyrimido[4,5-b][1,6]naphthyridines were successfully achieved from the reaction of the 2-aminonaphthyridine derivatives with the appropriate reagents. The structures of the isolated products were determined by elemental analysis and spectral methods (FT-IR, H-1-NMR, and C-13-NMR). The cytotoxicity of some of the prepared derivatives was also investigated. [GRAPHICS] .

Tailor-made naphthyridines: Self-assembling multiple hydrogen-bonded supramolecular architectures from dimer to helix

Stepwise changes of functional oxo and amino groups in 1,8-naphthyridines to modify the supramolecular architecture have been carried out. The first example of a naphthyridine helix has been found and its structure established by X-ray crystallography. The design is based on hydroxy and amido tautomeric naphthyridines which crystallize in dimers or catemers, one of them attaining helicity. The most stable tautomer present in all the compounds discussed in this paper, as well as the formation of hydrogen-bonded dimers or catemers, was established by X-ray crystallography and rationalized with theoretical calculations.
