The flow-vacuum pyrolyses of the title compounds 2, respectively 1, were performed between 300 deg C and 675 deg C (650 deg C), at 1 Torr.The results are discussed in comparison with those obtained in the previously described pyrolyses of the corresponding endo-isomers 5, respectively 4.

The flow-vacuum pyrolyses of title compounds 6 and 7 were examined at 1 Torr and various temperatures between 250 deg C (respectively 300 deg C) and 650 deg C. From both pyrolyses the following hydrocarbons were formed: 9,10-dihydro-9,10-propenoanthracene (1), 1,1a,6,10b-tetrahydro-1,6-methano-dibenzocyclopropacycloheptene (2), 11,11a-dihydro-6aH-benzofluorene (3), 6,11-dihydro-5H-benzofluorene (4), 11H-benzofluorene (5) and anthracene. Besides these products the epimeric exo-acetate 10 was formed in pyrolysis of endo-acetate 6 whereas from pyrolysis of 7 important amounts of corresponding ketone 9 were obtained. A radical mechanism is suggested.
