Bromination of 1,5-cyclooctadiene (1) and stepwise dehydro-enyne 4 are highly reactive dienophiles. The cycloadducts bromination first with KOtBu and then with KOtBu/l8-10-14 formed with 1,3-cyclohexadiene, carbon disulfide, crown-6 yields 1,5-~yclooctadiyne (5). A prolonged interac-and tetraphenylc
