Aminierung und para‐C–H‐Arylierung von Arylfluoriden vermittelt durch α‐Methylnaphthyl (MeNAP)‐Palladium‐Katalysatoren

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Katalysatoren, die aus dem halogenverbrückten Methylnaphthyl‐Palladium‐Dimer [Pd(1‐MeNAP)Br]2 und Biarylphosphin‐Liganden in Kombination mit der Base LiHMDS generiert werden, katalysieren Buchwald‐Hartwig‐artige Aminierungen und para‐C–H‐Arylierungen von nicht‐aktivierten Arylfluoriden bereits bei 60 °C.

Design and synthesis of amidine-type peptide bond isosteres: application of nitrile oxide derivatives as active ester equivalents in peptide and peptidomimetics synthesis. [PDF]

open access: yes, 2011
Amidine-type peptide bond isosteres were designed based on the substitution of the peptide bond carbonyl (C=O) group with an imino (C=NH) group. The positively-charged property of the isosteric part resembles a reduced amide-type peptidomimetic.

Amination and Para‐C─H Arylation of Aryl Fluorides Enabled by α‐Methylnaphthyl (MeNAP) Palladium Catalysts

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
Catalysts generated from the halogen‐bridged methylnaphthyl‐palladium dimer [Pd(1‐MeNAP)Br]2 and biarylphosphine ligands in combination with the base LiHMDS promote Buchwald‐Hartwig type aminations and para‐C─H arylations of non‐activated aryl fluorides already at 60 °C.
