KNH2 - KH: a metal amide - hydride solid solution [PDF]

, 2016
We report for the first time the formation of a metal amide-hydride solid solution. The dissolution of KH into KNH2 leads to an anionic substitution, which decreases the interaction among NH2 - ions.

Enantioselective synthesis of γ-chiral amides via copper-catalyzed reductive relay hydroaminocarbonylation

Nature Communications
Chiral amides are common and effective structural motifs found in many pharmaceuticals and biologically active molecules. Despite their importance, existing synthetic methods are predominantly employed for the synthesis of α-amides and β-amides.
