Tetrachlorobis(2-pyridone)-bis(μ2-2-pyridone)-dicopper

Acta Crystallographica Section C Crystal Structure Communications, 1993
In this structure two Cu II centres 3.4448 (11) A apart are bridged asymmetrically by two 2-pyridone ligands and each is further coordinated by three terminal ligands (two chlorides and one 2-pyridone). Each molecule has an approximate, non-crystallographic centre of symmetry.

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.
