SUMMA??Y: Treatment of 3-bromo-6,7-benzobicyclo c3.2.11 octa-2,3-diem? (9) with potassium tert.-butoxide produces the strained bicyclic allene (10) which is trapped by 1,3-diphenylbenzo[c]furan (DBI) to give five isomeric cycloadducts. In the absence of DBI, allene (10) gave rise to enol ether ( 18)
