By analogy, benzocyclopropene (1) is formed in low yield via biradical cyclization upon irradiation of benzocyclobutenone (79), upon its flash vacuum pyrolysis,68 or upon pyrolysis of indan-2,3-dione (80). 7o However, these latter extrusion methods are of no preparative interest. The l/3/elimination of o-substituted benzyl derivatives has been proposed as an alternative synthesis of cycloproparenes. Thus intmmolecular cyclization of obromo-ct-methoxytoluene (82) via lithiation to benzocyclopropene (1) has been claimed to proceed with a yield of about 30%.
