N-Aryl amide synthesis from α-fluoronitroalkane and N-aryl hydroxyl amine.^a

^aGeneral procedure: The aryl hydroxylamine (1.5 equiv), Cs₂CO₃ (3 equiv), and fluoronitroalkane were stirred in solvent (0.05 M) in a vial for 24 h.

Yields were measured by ¹H NMR (relative to CH₂Br₂) after filtration through a pad of silica gel. Isolated yields (after chromatography for most compounds) are reported in the SI.
