ChemInform Abstract: Concise Entries to 4‐Halo‐2‐pyridones and 3‐Bromo‐4‐halo‐2‐pyridones. [PDF]
Methods for the synthesis of both simple 4-halo-2-pyridones and more functionalized 3,4-di- and (3,4,5-tri)-halo-2-pyridones are described that are based on a combination of Sandmeyer and regioselective (copper-mediated) halogenation, with a 2-chloro or a 2-benzyloxy moiety serving as a masked 2-pyridone.

Dichlorido[1-(1,10-phenanthrolin-2-yl)-2-pyridone]cadmium(II)
In the title mononuclear complex, [CdCl2(C17H11N3O)], the CdII ion assumes a distorted trigonal–bipyramidal coordination geometry. The pyridone plane is twisted out of the 1,10-phenanthroline mean plane by 43.8 (3)°.

Ligand‐Enabled Nondirected and Regioselective Arylation of Internal Alkenes with Simple Arenes
A regioselective insertion of (hetero) aryl groups into the C−C double bond of unactivated internal alkenes by nondirected arene‐C(sp2)−H activation has been achieved. The design and development of a new ligand‐supported palladium catalysis, enables quick access to trisubstituted alkenes, especially E‐1,2‐diarylalkenes, from unfunctionalized simple raw

Designing Enzymatic Reactivity with an Expanded Palette
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

6-Methyl-2-pyridone pentahydrate [PDF]
Crystals of the title compound, C6H7NO·5H2O, were grown over a period of several weeks from an aqueous solution of the commercial compound. The molecule crystallizes in space group P\overline 1 and there are two independent 6-methyl-2-pyridone (Hmhp) molecules in the asymmetric unit, together with ten molecules of water.
