Abstract
Pyrolysis of 2,3,3a,8,8a-hexahydro-2,3,8-methenocyclopentindene in a f low system at 1.33 mbar, in an argon atmosphere and at temperatures be tween 500 and 750 degrees C was studied by GC/MS. The first pyrolysis product, 1,6-dihydro-1,6-methanobenzo[d]cyclooctene (a new compound), was converted at elevated temperatures into mainly alpha- and beta-all ylnaphthalenes and fluorene. A reaction mechanism including radical an d concerted steps is suggested.
