چکیده
In the title mol-ecule, C(17)H(12)N(2)O(3), the naphthalene ring system and the pyridin-3-yl rings are nearly coplanar with a dihedral angle between them of 2.28 (8)°. In the crystal, the hy-droxy and amide N atoms participate in hydrogen bonds, which connect the mol-ecules into a two-dimensional network parallel to (101).

Investigating the interaction of sunset yellow aggregates and 6-fluoro-2-naphthoic acid: increasing probe molecule complexity.
The interaction of small molecules with non-covalent assemblies is of wide interest. The use of a magnetically active reporter nucleus allows information to be obtained in the presence of spectral overlap or in cases of high dynamic range. In this paper, we explore the interaction of a larger probe molecule, 6-fluoro-2-naphthoic acid with assemblies of sunset yellow using (19)F chemical shifts ...
متن کاملAnaerobic Naphthalene Degradation by a Sulfate-Reducing Enrichment Culture
Anaerobic naphthalene degradation by a sulfate-reducing enrichment culture was studied by substrate utilization tests and identification of metabolites by gas chromatography-mass spectrometry. In substrate utilization tests, the culture was able to oxidize naphthalene, 2-methylnaphthalene, 1and 2-naphthoic acids, phenylacetic acid, benzoic acid, cyclohexanecarboxylic acid, and cyclohex-1-ene-ca...
متن کاملAnaerobic degradation of polycyclic aromatic hydrocarbons.
Polycyclic aromatic hydrocarbons (PAHs) are among the most important contaminants of groundwater. The 2- and 3-ring PAHs are of particular concern because they are water soluble in the 1-200 mug/l range and are transported with the groundwater over significant distances. Anaerobic degradation of PAH has been demonstrated in several microcosm studies with nitrate, ferric iron, or sulfate as elec...
متن کاملMethod for the rapid synthesis of highly functionalized 2-hydroxy-1-naphthoates. Syntheses of the naphthoic acid components of neocarzinostatin chromophore and N1999A2.
We describe a four-step sequence for the synthesis of complex 2-hydroxy-1-naphthoic acids involving Z-selective olefination of benzaldehyde derivatives with a novel dioxolenone-containing phenyl phosphonate reagent, followed by dioxolenone cleavage with alkaline trifluoroethanol and oxidative cyclization (Mn(OAc)(3)) of the resultant trifluoroethyl beta-keto esters.

متن کاملMixed ligand complexes of alkali metal salts of salicylic acid, acetyl salicylic acid and 2-hydroxy-3-naphthoic acid with 2,5 dihydroxybenzoquinone
Mixed ligand complexes of general formula (ML)2. H2BQ, where M = Li, Na or K, L = deprotonated salicylic acid, acetylsalicyilc acid or 2-hydroxy-3-napthoic acid; H2BQ = 2, 5idhydroxybenzoquinone have been synthesized and characteriszed. The infrared studies indicate the presence of intramolecular hydrogen bonding in the complexes, whcih may be one of the factors for stabilizing them.
