Conservation of the Hydrogen-Bonded Pyridone Homosynthon in Halogen-Bonded Cocrystals [PDF]
, 2022 Seven cocrystals of pyridone and perfluorinated halocarbons have been prepared. In all cases pairs of pyridone molecules are connected into dimers by two N–H···O hydrogen bonds, forming the characteristic pyridone homosynthon of R22(8) topology.

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity
Angewandte Chemie, EarlyView.This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

The Biochemical Pathways of Nicotinamide-Derived Pyridones [PDF]
International Journal of Molecular Sciences, 2021 As catabolites of nicotinamide possess physiological relevance, pyridones are often included in metabolomics measurements and associated with pathological outcomes in acute kidney injury (AKI). Pyridones are oxidation products of nicotinamide, its methylated form, and its ribosylated form.

The Ring Transformation of 3-Methyl-5-nitropyrimidin-4(3H)-one
Molecules, 2003 3-Methyl-5-nitropyrimidin-4(3H)-one readily reacts with carbonyl compounds to produce three kinds of ring transformations. The nitropyrimidinone behaves as the synthetic equivalent of activated diformylamine affording 3,5-difunctionalized 4-pyridones, 4 ...

Ultrafast Decay Dynamics of the 21ππ* Electronic State of N‑Methyl-2-pyridone [PDF]
The ultrafast decay dynamics of N-methyl-2-pyridone upon excitation in the near-ultraviolet range of 261.5–227.9 nm is investigated using the femtosecond time-resolved photoelectron spectroscopy method.
