A wide range of N-phenylated secondary amines were prepared directly from 2-oxo-7-azobicyclo[4.1.0]heptanes using 4-nitrobenzoic acid as acid catalyst. The intermediate enol esters could also be isolated under similar conditions. A catalytic cycle is proposed.

Sodium benzoate reacts with α-halo-α,β-enones in the presence of tetrabutylammonium hydrogensulfate or 18-Crown-6 to afford α- and/or γ-benzoyloxylated α,β-enones in good yield. The α/γ and γ/γ′ selectivities are dependent on the substrate and reagent.
