Dinuclear oxidative addition reactions using an isostructural series of Ni-2, Co-2, and Fe-2 complexes

A family of low-valent Ni-2, Co-2, and Fe-2 naphthyridine-diimine (NDI) complexes is presented. Ligand-based pi* orbitals are sufficiently low-lying to fall within the metal 3d manifold, resulting in electronic structures that are highly delocalized across the conjugated [NDI]M-2 system. This feature confers stability to metalmetal interactions during two-electron redox reactions, as demonstrated in a prototypical oxidative addition of allyl chloride.

Structural Characterization of Di- and Mono-Imidazolyl-Substituted 1,8-Naphthyridine Derivatives

Two imidazolyl derived 1,8-naphthyridine compounds (2,7-diimidazolyl-1,8-naphthyridine (a), and 2-benzimidazolyl-5,7-dimethyl-1,8-napthyridine (b)) were synthesized and structurally characterized by X-ray crystallography.

Polymerization Mechanism of Nitrogen-Containing Heteroaromatic Compound Under High-Pressure and High-Temperature Conditions

Hydrogenated carbon nitride is synthesized by polymerization of 1,5-naphthyridine, a nitrogen-containing heteroaromatic compound, under high-pressure and high-temperature conditions. The polymerization progressed significantly at temperatures above 573 K at 0.5 GPa and above 623 K at 1.5 GPa. The reaction temperature was relatively lower than that observed for pure naphthalene, suggesting that the reaction temperature is considerably lowered when nitrogen atoms exist in the aromatic ring structure. The polymerization reaction largely progresses without significant change in the N/C ratio. Three types of dimerization are identified; naphthylation, exact dimerization, and dimerization with hydrogenation as determined from the gas chromatograph-mass spectrometry analysis of soluble products. Infrared spectra suggest that hydrogenation products were likely to be formed with spa carbon and NH bonding. Solid-state C-13 nuclear magnetic resonance reveals that the sp(3)/sp(2) ratio is 0.14 in both the insoluble solids synthesized at 0.5 and 1.5 GPa. Not only the dimers but also soluble heavier oligomers and insoluble polymers formed through more extensive polymerization. The major reaction mechanism of 1,5-Nap was common to both the 0.5 and 1.5 GPa experiments, although the required reaction temperature increased with increasing pressure and aromatic rings preferentially remained at the higher pressure.

Synthesis and peripheral substituent effects of bay-annulated indigo derivatives

In this study, indolo-naphthyridine-6,13-diones (5a-d) with four different peripheral substituents were prepared via bay-annulation reactions of indigo. The resulting compounds (5a-d) exhibited fluorescence in the red to near-IR region, while the parent indigo molecule showed no fluorescence. Although the peripheral substituents were oriented to the exterior of the pi-conjugated system, the electronic structure affected the absorption and fluorescence spectra. Moreover, calculated molecular orbitals and absorption spectra successfully reproduced the experimental absorption spectra and cyclic voltammograms. (C) 2018 Elsevier Ltd. All rights reserved.

Oxygen activation at a dicobalt centre of a dipyridylethane naphthyridine complex

The mechanism of oxygen activation at a dicobalt bis-mu-hydroxo core is probed by the implementation of synthetic methods to isolate reaction intermediates. Reduction of a dicobalt(III, III) core ligated by the polypyridyl ligand dipyridylethane naphthyridine (DPEN) by two electrons and subsequent protonation result in the release of one water moiety to furnish a dicobalt(II, II) center with an open binding site. This reduced core may be independently isolated by chemical reduction. Variable-temperature H-1 NMR and SQUID magnetometry reveal the reduced dicobalt(II, II) intermediate to consist of two low spin Co(II) centers coupled antiferromagnetically. Binding of O-2 to the open coordination site of the dicobalt(II, II) core results in the production of an oxygen adduct, which is proposed to be a dicobalt(III, III) peroxo. Electrochemical studies show that the addition of two electrons results in cleavage of the O-O bond.

Eleven supramolecular adducts of 5,7-dimethyl-1,8-naphthyridine-2-amine and organic acids assembled by classical hydrogen bonds and other noncovalent intermolecular interactions

This article demonstrates 5,7-dimethyl-1,8-naphthyridine-2-amine based supramolecular adducts formation in eleven crystalline solids 1-11, in which the acidic moiety have been integrated. Addition of equivalents of the acid to the solution of 5,7-dimethyl-1,8-naphthyridine-2-amine generates the corresponding supramolecular assemblies. Except 8, all the compounds crystallize as their organic salts with the acidic proton at the organic acids transferred to the aromatic nitrogen of the 5,7-dimethyl-1,8-naphthyridine-2-amine moiety. All adducts have been characterized through IR, mp, elemental analysis and X-ray single crystal diffraction technique. The major driving force in the adducts 1-11 is attributed to the classical hydrogen-bonds arising from 5,7-dimethyl-1,8-naphthyridine-2-amine and the acids. The other extensive non-covalent interactions also play great functions in space association of the molecular counterparts in relevant crystals. The homo or hetero supramolecular synthons or both were found at these adducts. The common R-2(2)(8) graph set has been observed in all of the adducts due to the H-bonds and the non-covalent associations. For the synergistic interactions of the classical H-bonds and the various non-covalent associations, these adducts displayed 2D/3D structures. (C) 2017 Elsevier B.V. All rights reserved.
