Tricyclo[3.3.0.02 8]oct-3-enes are conveniently obtained by the photocycloaddition of ethenes to benzenoidcompounds. Acid catalyzed cleavage of the cyclopropane ring in the photoadduct affords bicyclo[3.3.0] and [3.2.1]octane derivatives and dienophiles undergo [2π+2π] and [2π+2σ+2π] cycloaddition to the ethene and ethenylcyclopropane moieties respectively. The preferred mode of reaction for both
