Benzocylo-octenes. Part 4. Benzo- and Dibenzo-cyclo-octene Synthesis via Benzocyclobutene

The cycloadduct of benzocyclobutene with 2H-pyran-2-one readily undergoes thermal elimination of carbon dioxide and subsequent valence isomerisation to give benzocyclo-octene; analogous reactions of benzocyclobutene with alkyl and aryl derivatives of 2H-p
