Structural Studies of [Ru(1,8-naphthyridine)(4)](2+) and [Ru(1,5-cyclooctadiene)(1,8-naphthyridine)(2)](2+) as their Tetraphenylborate Salts

The previously reported [Ru(naph)(4)](2+) complex (naph = 1,8-naphthyridine) has been prepared by a simplified route using [RuCl2(1,5-COD)](x) (COD = cyclooctadiene) as starting material and isolated as its tetraphenylborate salt. The salt crystallizes in the monoclinic space group P2(1)/n with a = 13.6531(3) angstrom, b = 12.5389(4) angstrom, c = 20.0349(5) angstrom, beta = 96.5884(15)degrees, V = 3407.22(16) angstrom, D-calc = 1.300 at 150(1) K. The dication has crystallographically imposed inversion symmetry. Although the iron analogue has been found to have a coordination number of eight, the ruthenium complex is only six-coordinate, which is achieved by the presence of two monodentate and two bidentate 1,8-naphthyridine ligands. The observation of a higher coordination number for Fe(II) vs. Ru(II) can be explained by the high spin nature of the iron complex. A byproduct complex, [Ru(1,5-COD)(naph)(2)] [B(C6H5)(4)](2), could also be synthesized, isolated pure, and structurally characterized. The organometallic complex possesses an 18 electron configuration by virtue of the dicationic metal center being coordinated by the diene ligand and all four nitrogen lone pairs. This salt crystallizes in the triclinic space group P (1) over bar with a = 12.9538(3) angstrom, b = 14.9485(3) angstrom, c = 17.4291(3) angstrom, alpha = 69.0649(11)degrees, beta = 78.3211(9)degrees, gamma = 78.5629(10)degrees, V = 3057.50(11) angstrom(3), D-calc = 1.293 at 150(1) K.

Catalytic Reduction of Nitroarenes by Dipalladium Complexes: Synergistic Effect

The direct reaction between 2,7-bis(2-pyridinyl)-1,8-naphthyridine (bpnp) and Pd(CH3COO)(2) in CF3COOH yields the new dinuclear palladium(II) complex [Pd-2(bpnp)(mu-OH)(CF3CO2)(2)](CF3CO2) (1). Similarly, substitution of Pd(CH3CN)(4)(BF4)(2) with bpnp in DMF gives [Pd-2(bpnp)(mu-OH)(DMF)(2)](BF4)(3) (2). Treatment of 1 or 2 with Cl- readily provide the chloro-substituted species [Pd(bpnp)(mu-OH)(Cl)(2)](+). All complexes were characterized by spectroscopic methods, and the structure of 2 was further confirmed by X-ray crystallography. Complex 1 is an efficient catalyst for the reduction of aromatic nitro compounds leading to the corresponding aniline derivatives under atmospheric pressure of hydrogen at 50 degrees C. The mechanistic pathway of the catalysis is investigated. From the reaction pathway, it is suggested that a facile condensation of nitroso and hydroxylamine intermediates is enabled by the dipalladium system and the desired transformation proceeds smoothly under mild reaction conditions to yield the reduced product.

Novel 3-fluoro-6-methoxyquinoline derivatives as inhibitors of bacterial DNA gyrase and topoisomerase IV

Novel (non-fluoroquinolone) inhibitors of bacterial type II topoisomerases (NBTIs) are an emerging class of antibacterial agents. We report an optimized series of cyclobutylaryl-substituted NBTIs. Compound 14 demonstrated excellent activity both in vitro (S. aureus MIC90 = 0.125 mu g/ mL) and in vivo (systemic and tissue infections). Enhanced inhibition of Topoisomerase IV correlated with improved activity in S. aureus strains with mutations conferring resistance to NBTIs. Compound 14 also displayed an improved hERG IC50 of 85.9 mu M and a favorable profile in the anesthetized guinea pig model. (C) 2017 Elsevier Ltd. All rights reserved.

The effect of reduction on rhenium(I) complexes with binaphthyridine and biquinoline ligands: A spectroscopic and computational study

A number of rhenium complexes with binaphthyridine and biquinoline ligands have been synthesized and studied. These are [Re(L)(CO)(3)Cl] where L = 3,3′-dimethylene-2,2′-bi-1,8-naphthyridine (dbn), 2,2′-bi-1,8-naphthyridine (bn), 3,3′-dimethylene-2,2′-biquinoline (dbq), and 3,3′-dimethyl-2,2′-biquinoline (diq). This series represents ligands in which the electronic properties and steric preferences are tuned. These complexes are modeled using density functional theory (DFT). An analysis of the resonance Raman spectra for these complexes, in concert with the vibrational assignments, reveals that the accepting molecular orbital (MO) in the metal-to-ligand charge transfer (MLCT) transition is the LUMO and causes bonding changes at the interring section of the ligand. The electronic absorption spectroelectrochemistry for the reduced complexes of [Re(dbn)(CO)(3)Cl], [Re(dbq)(CO)(3)Cl], and [Re(diq)(CO)(3)Cl] suggest that the singly occupied MO is delocalized over the entire ligand structure despite the nonplanar nature of the diq ligand in [Re(diq)(CO)(3)Cl]. The IR spectroelectrochemistry for [Re(dbn)(CO)(3)Cl], [Re(dbq)(CO)(3)Cl], and [Re(bn)(CO)(3)Cl] reveal that reduction lowers the CO ligand vibrational frequencies to a similar extent in all three complexes. The substitution of naphthyridine for quinoline has little effect on the nature of the singly occupied MO. These data are supported by DFT calculations on the reduced complexes, which reveal that the ligands are flattened out by reduction: This may explain the similarity in the properties of the reduced complexes.

A 1,2-Addition Pathway for C(sp(2))-H Activation at a Dinickel Imide

A dinickel imido complex was synthesized using a redox-active naphthyridine-diimine supporting ligand. Upon coordination of an external ligand, the Ni-2 core was disrupted, triggering an aromatic C-H activation reaction to generate a Ni-2 (mu-NHAr)(Ar) species. This intermediate is capable of liberating free carbazole and phenanthridine products upon heating or treatment with excess tBuNC. Collectively, these studies establish a kinetically facile 1,2-addition mechanism for C(sp(2))-H activation, taking advantage of cooperative reactivity between two Ni centers.

Fluorescent organic nanoparticles of benzofuran-naphthyridine linked molecules: Formation and fluorescence enhancement in aqueous media

Enthynyl-linked benzofuran-naphthyridine compounds show high-yield fluorescence with solvatochromic properties. One of the compounds, ABAN, has successfully formed fluorescent organic nanoparticles (FONs), for which the photophysical properties such as the spectral features and intensity are remarkably different from those at the molecular level (solution) and in bulk material. The results are tentatively rationalized by the FONs inducing coplanarization of the benzofuran-naphthyridine molecule to extend its effective conjugation length and hence increase the oscillator strength.
