An in-ketocyclophane.
Computational studies indicate that some benzophenone-capped cyclophanes should have carbonyl groups pointed directly at their basal benzene rings as a result of conformational restraints imposed by bulky groups in the linking arms of the molecules. Cyclophane 4 was prepared, and its X-ray structure shows it to be the first in-ketocyclophane.
