Electron‐rich diaminoalkynes with a variable substitution pattern can be conveniently prepared by lithiation of 2,2‐dibromo‐1,1‐ethenediamines; the alkynes are formed by a Fritsch–Buttenberg–Wiechell rearrangement of intermediate LiBr–vinylidene species. The first two X‐ray crystal structures of diaminoalkynes are presented, which show almost perpendicular orientations of the NC 3 planes.
