reaction of aliphatic acyclic α,α′-dibromoketones with primary amines gave rise to α-iminoketones and α-diimines. Both reaction products could be selectively obtained under appropriate reaction conditions. Sterically hindered α,α-dibromoketones did not react with primary amines, although, under forcing conditions the Favorskii rearrangement could be induced. In aqueous methanol, α,α′-dibromoketones reacted
