title: Cage hydrocarbons derived from dibenzosuberenone.
abstract: The reinvestigation of the synthesis of the fascinating cage compound 2 reveals an incorrect structure of photodimer 2, as well as of the putatively isolated intermediate 9. These products have to be reassigned as monomeric pyramidalized alkene 3 and spirocyclic dichloride 10, respectively.
