DFT/B3-LYP study of the hydrogen-bonding cooperativity: application to (2-pyridone)2, 2-pyridone–H2O, 2-pyridone–CH3OH and 2-pyridone–CH3OCH3

Chemical Physics Letters, 2000
Abstract DFT/B3-LYP(6-31++G**) calculations are used to provide information on closed N – H ⋯ O H -bonded complexes, containing two hydrogen bonds. The studied model systems with two H-bonds are the 2-pyridone dimer, 2-pyridone–H2O and 2-pyridone–CH3OH.

Chlorosulfonation of 2-pyridones

Chemistry of Heterocyclic Compounds, 1974
Chlorosulfonlyl-substituted 2-pyridones were obtained for the first time. The ability of 2-pyridone-3-sulfonyl chlorides to undergo conversion to sulfonylides of the pyridine series by the action of bases is shown in the case of 5,6,7,8-tetrahydro-2-quinolone-3-sulfonyl chloride.

Charge Density Study of 2-Pyridone

Acta Crystallographica Section B Structural Science, 1998
The crystal structure of 2-pyridone has been redetermined from high-resolution X-ray data collected at 123 K. The molecule is in the lactam form. Bond lengths (corrected for rigid-body libration) and angles have been determined with s.u.'s of 0.001 Å and 0.1°, respectively.

Photoreactions of alkylated 2-pyridones

Journal of the Chemical Society, Perkin Transactions 2, 1985
Photoisomerisation and dimerisation reactions in solution have been studied with a series of alkylated 2- pyridones (1). The low quantum efficiencies for the photoisomerisation (0.01–0.07) are related to the short-lived singlet excited states (below 1 ns). The effects of temperature, solvent, and substrate concentration were also examined.

2-Pyridone Synthesis Using 2-(Phenylsulfinyl)acetamide

Organic Letters, 2012
2-Pyridones were prepared by means of an efficient protocol including the 1,4-addition of 2-(phenylsulfinyl)acetamide to α,β-unsaturated ketones followed by cyclization and sulfoxide elimination.

Photoionization of 2-pyridone and 2-hydroxypyridine

Physical Chemistry Chemical Physics, 2010
We studied the photoionization of 2-pyridone and its tautomer, 2-hydroxypyridine by means of VUV synchrotron radiation coupled to a velocity map imaging electron/ion coincidence spectrometer. The photoionization efficiency (PIE) spectrum is composed of steps.

Über 6‐Thiazolyl‐2‐pyridone

Helvetica Chimica Acta, 1961
6‐Thiazolyl‐2‐pyridones, a new class of chelating agents of the bipyridyl type, have been synthesized from the thioamide of 2‐pyridone‐6‐carboxylic acid; the latter has been obtained starting from the acid via the ethyl ester, amide and nitrile.
