Abstract
Diphenylbutadiyne on flash vacuum pyrolysis at 1120-degrees/0.03 Torr gave a pyrolysate (22% mass recovery) consisting of the diyne (7%), in deno[2,1-a]indene (19%), fluoranthene (59%), acephenanthrylene (13%) a nd aceanthrylene (2%). It is proposed that indeno[1,2-a]indene is form ed via 3-phenyl-1,2-didehydronaphthalene and fluoranthene via 1-phenyl -2,3-didehydronaphthalene.
