Yields of 74% were obtained for the preparation of 2 from the tetrameric cavitand 1 in the presence of pyrazine. This first bis(carceplex) may provide a unique opportunity for studying guest-guest communication by virtue of the close proximity of the two covalently attached capsules, which, according to MM2 calculations, are rotated by 90° with respect to each other.
