Treatment of 3-bromo-6,7-benzobicyclo<3.2.1>octa-2,3-diene (9) with potassium tert.-butoxide produces the strained bicyclic allene (10) which is trapped by 1,3-diphenylbenzofuran (DBI) to give five isomeric cycloadducts.In the absence of DBI, allene (10) gave rise to enol ether (18) by addition of tert.-butanol.
