Abstract
The title hydrocarbon (11) reacts thermally by two competitive routes: (a) a retrodiene reaction affording anthracene and (b) a sequence of isomerizations generating 9,10-dihydro-9,10-propenoanthracene (1), 1,1 a,6,10b-tetrahydro-1,6-methano-dibenzo[a,e] cyclopropa[c]cycloheptene (2), 11,11a-dihydro-6aH-benzo[a]fluorene (4), 6,11-dihydro-5H-benzo[a] fluorene (5) and finally through dehydrogenation 11H-benzo[a]fluorene (6).
