The title compound 7, a new dibenzo-(C9H10)hydrocarbon, was synthesized from Cava's angular dimer of benzocyclobutadiene through dibromocarbene addition followed by LiAlH4-reduction.Flow-vacuum pyrolysis of 7 afforded: 1a,9a-dihydro-9H-benzofluorene (10) (new compound), 1,2-dihydro-9H-benzofluorene (11) and 9H-benzofluorene (12).The new compounds were characterized by IR-, UV-, and 1H-NMR data.A reaction mechanism involving radical- and concerted steps is suggested for pyrolysis of 7.

Same cyclohexadienols, when heated at 220 deg C with PyHCl, gave, through dehydration and isomerisation, the corresponding benzene derivatives.So 2,6-dibenzyliden-cyclohexanols gave m-dibenzyl-benzenes, 2-benzyliden-1-tetralols gave 2-benzyl-naphtalenes a
