The title reaction gave a 2+2 cycloadduct, 8,9-benzo-cis-bicyclo[5.2.0]nona-2,4,8-triene 7, together with ene product, 7-phenylcycloheptatriene. The structure of 7 was confirmed by catalytic reduction to give 8,9-benzo-cis-bicyclo[5.2.0]non-8-ene, which was also obtained in the reaction of benzyne with cycloheptene, and by reduction of the known 8,9-benzobicyclo[5.2.0]nona-1,8-diene. Other benzo(C9H10)
标题反应得到2 + 2环加合物,8,9-苯并顺式-双环[5.2.0]壬娜-2,4,8-三烯7,以及烯产物7-苯基环庚三烯。的结构7通过催化还原证实,得到8,9-苯并顺-二环[5.2.0]壬-8-烯,其还与环庚苯炔的反应获得,并通过还原已知8的,9-苯并双环[5.2.0] nona-1,8-二烯。其它苯并(C 9 ħ 10已被合成的)烃是7,8- benzobicyclo [4.2.1]壬-2,4,7-三烯5,2,3- benzobicyclo [6.1.0]壬-2,4- ,6-三烯28和4,5-苯并双环[6.1.0] nona-2,4,6-三烯29。的热分解描述了7,28,29和3,4-苯并-外-内-四环[4.3.1.0 3,4 .0 7,9 ] dec-3-en-10-one,25的描述。
