Application of 1569-16-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1569-16-0, Name is 2-Methyl[1,8]-Naphthyridine, molecular formula is C9H8N2. In a Article£¬once mentioned of 1569-16-0

A number of 4-aminopyrazolo[3,4-b]pyridines 5-carboxylic acid esters (2-8) were synthesized and evaluated for their binding affinity at the A1, A2A, and A3 adenosine receptors (AR), in bovine cortical membranes, as well as for their affinity toward human A1AR (hA 1AR). Some of the new compounds were characterized by a high affinity and selectivity toward the A1 receptor subtype, showing a significant improvement in comparison with other pyrazolo-pyridines previously reported in the literature. In particular the methyl ester 2h as well as the isopropyl ester 5h, both of them bearing a p-methoxyphenylethylamino side chain at the position 4, presented K1 values of 6 and 7 nM, respectively. To rationalize the relationships between structure and affinity of the novel compounds, a 3D QSAR model was also generated starting from compounds belonging to different classes of known A1AR antagonists. 2005 American Chemical Society.

New ruthenium complexes with 1,8-naphthyridine (napy) or derivatives thereof as ligands have been prepared and characterized. Three groups of complexes were obtained. The first consists of three dinuclear ruthenium complexes with two ligands (1,8-naphthyridine and pyridopyrazine) co-ordinated to two ruthenium ions in a bridging fashion. The second consists of two ruthenium dinuclear complexes having one ligand (2,7-dimethoxy-or 2,7-dichloro-1,8-naphthyridine, abbreviated to dmnapy and dcnapy respectively) co-ordinated to two ruthenium atoms. Proton NMR spectra for both complexes in aqueous solution and in acetonitrile revealed the conversion of a symmetrical form, suggesting dinucleating behaviour of the ligand, into an asymmetrical form, suggesting mononucleating behaviour of the ligand. The third group consists of a mono- and a di-nuclear complex with the ligand 2,7-di(phenylazo)-1,8-naphthyridine. The catalytic activity of the novel naphthyridine complexes in oxidation reactions has been studied. The catalytic oxidation of alcohols and the epoxidation of trans-stilbene were examined and the different reaction rates and selectivities are discussed in a comparative way. The active high-valent species resulting from the [Ru2(napy)2(H2O)4Cl(OH)] 4+ complex is discussed in more detail.

A conjugated donor-acceptor-donor molecule incorporating a central moiety of naphthyridine and two terminal moieties of di(hydroxyethyl)aniline connected by ethynyl bridges shows two-stage color changes on binding with mercury(II) ion in Me2SO/H2O (1:1) solution with a bathochromic shift from 450 to 498 nm, and then an extraordinarily large hypsochromic shift to 378 nm. In comparison, the corresponding donor-acceptor molecule weakly binds mercury(II) ion with a hypsochromic shift from 408 to 375 nm. Our designed sensor of the donor-acceptor-donor system shows high selectivity toward mercury(II) ion over other competing metal ions.

The complexes [Ru(bipy)2(napy-N)(MeCN)][PF6]2 1 and [Ru(bipy)2(napy-N,NA?);][PF6]2 2(bipy = 2,2?-bipyridine, napy = 1,8-naphthyridine) were prepared, and their crystal structures determined by X-ray analysis. The crystal structure of 1 displays an octahedral co-ordination with monodentate napy, acetonitrile and two chelating bipy. Despite the inequivalency of two nitrogens of napy in 1 in the solid state, the 1H NMR spectra in the aromatic region resemble those of 2 over the range -90 to 60C, which implies dynamic behaviour of napy in 1 in solution. Both 1 and 2 were reduced irreversibly at -0.98 V (vs. Ag-AgCl) in dimethylformamide at -20C, and the process gradually becomes a reversible redox reaction on increasing the temperature to 30C. An EPR study revealed that one-electron reduction of 1 takes place in the napy-localized orbital without appreciable increase in electron density on one of the nitrogens of napy. The distinct inequivalence in the charge density between the two nitrogen atoms of singly reduced napy results in stabilization of the N rather than N,N? co-ordination mode.

The controlled potential electrolysis of [Ru(bpy)(napy)2(CO)2](BF4)2 (1; bpy = 2,2′-bipyridine, napy = 1,8-naphthyridine) in the presence of LiBF4 in CO2-saturated DMSO at -1.65 V (vs. Ag/Ag+) produced CO and Li2CO3 [Eq. (a)], while similar electrolysis in the presence of (CH3)4NBF4 resulted in formation of acetone together with (CH3)3N and {(CH3)4N}2CO3 [Eq. (b)]. This represents the first almost selective generation of acetone upon electrochemical reduction of CO2. The selectivity is ascribed to depression of reductive cleavage of the Ru-CO bond of 1 due to an attack of the nonbonded nitrogen atom of napy at the carbonyl carbon atom.
