## Abstract In continuation of previous work on cyclopentadienone dimers [3], thermal and photochemical interconversions of the isomeric diketones **1, 3**, and **5** by skeletal rearrangements have been established to the extent summarized in schemes 2 and 3, and the intramolecular [2+2] cycloaddi
