The reaction of 2-bromoenones with N-unsubstituted 1,2-diamines was studied. An easy access to 1,4-diazabicyclo[4.1.0]hept-4-enes was developed. The multistep mechanism of the reaction is discussed. Final conclusions on the influence of the structure of the starting 2-bromoenones and 1,2-diamines on the direction of the reaction are established.
