Diphenylbutadiyne on flash vacuum pyrolysis at 1120°/0.03 Torr gave a pyrolysate (22% mass recovery) consisting of the diyne (7%), indeno[2,1-a]indene (19%), fluoranthene (59%), acephenanthrylene (13%) and aceanthrylene (2%). It is proposed that indeno[1,2-a]indene is formed via 3-phenyl-1,2-didehydronaphthalene and fluoranthene via-phenyl-2,3-didehydronaphthalene.
于1120°/ 0.03 Torr进行快速真空热解的二苯基丁二炔产生了热裂解物(质量回收率为22%),由二炔(7%),茚并[2,1- a ]茚(19%),荧蒽(59%)和对苯二酚组成(13%)和乙炔(2%)。所以建议茚并[1,2一]茚形成经由3-苯基-1,2- didehydronaphthalene和荧蒽通过-苯基-2,3- didehydronaphthalene。
