FVT of acenaphtho[1,2-a]acenaphthylene (1) gave acenaphtho[1,2-e]acenaphthylene (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 carboncarbon single bond of 1 is an important competitive process.
VT [1,2- a ] ac(1)的FVT得到gave [1,2- e ] ac(2),环戊[ cd ] per(3)和环戊[ rst ]苯并[ hi ](4)。形成3和4表明,除了的环缩/扩环1给予2,一个五元环carboncarbon的单键的均裂1是一个重要的竞争过程。
