Abstract
The formation of cyclopenta[cd]pyrene (5) and benzo[ghi]fluoranthene ( 6) upon FVT of 3,9-bisethynylphenanthrene (1) and 8-ethynylfluoranthen e (2), respectively, suggests that redundant ethynyl substituents, whi ch cannot give five- and/or six-membered ring formation via ethynyl et hylidene carbene equilibration followed by carbene C-H insertion, can migrate along the PAH periphery at high temperatures.
