The action of potassium t-butoxide in diglyme on trans,anti,trans- and trans,syn,trans-1,2,5,6-tetrabromocyclo-octane and on cyclo-octatetraene was found to produce benzocyclobutene, styrene, cyclo-octa-1,3,5-triene, and ethylbenzene. Similar base treatment of 1,2,5,6,9,10-hexabromocyclododecane gave the hitherto unknown 1,2-benzocyclo-octa-1,3,5-triene while 1,2,5,6-tetrabromocyclododecane produced
叔丁醇钾的二甘醇二甲醚中的动作的反式,反,反式-和反式,顺式,反式-1,2,5,6- tetrabromocyclo辛烷和环octatetraene被发现产生苯并环丁烯,苯乙烯,环-辛-1,3,5-三烯和乙苯。对1,2,5,6,9,10-六溴环十二烷进行类似的碱处理得到了迄今未知的1,2-苯并环-八-1,3,5-三烯,而1,2,5,6-四溴环十二烷产生了1,2 -苯并环-辛-1-烯。
