Abstract
FVT of acenaphtho[1,2-a]acenaphthylene (1) gave acenaphtho[1,2-e]acenaphthy lene (2). cyclopenta[cd]perylene (3) and cyclopenta[rst]benzo[hi]chrysene ( 4). The formation of 3 and 4 indicates that, besides ring contraction/ring expansion of 1 giving 2, homolytic scission of a five-membered ring carbon- carbon single bond of 1 is an important competitive process.
