The development of a broadly applicable procedure for the aza-Lossen rearrangement is reported. This process converts amines into complexhydrazinederivatives in two steps under safe, mild conditions. This method allows the chemoselective formation of N–N bonds, resulting in the synthesis of cyclic and acyclic products while avoiding side reactions of the amphoteric (ambident) nitrogen-substituted
