New benzimidazolidinone cyclophanes were synthesized through a double Stevens rearrangement employed as a ringexpansion technique. Para-substituted heterophanes underwent efficient rearrangement. Meta-substituted heterophanes were also prepared. Structure analyses of the new cyclophanes are also provided. [reaction: see text]
