Thermolysis of benzopyranone-indenone adducts 1, probably proceeding via o-quinodimethanes 10, gives C-nor-D-homo steroids 4, benzofluorenones 5, and traces of benzocyclopropafluorenones 6.Evidence is presented for the intervention of a biradica

Generation of o-quinodimethane systems and their rearrangement reactions during thermolysis of benzopyranone-indenone adducts 9 have been studied.Three products have been obtained: a C-nor-D-homo steroid, 12, a benzofluorenone, 13, and a benzocyclop
