Fullerene tectonics. Part 2. Synthesis and pyrolysis of halogenated benzo[c]phenanthrenes

Plater, M. John

, p. 2903 - 2909 (1997)

Halogenated benzo[c]phenanthrenes with a halogen in the hindered fiord region are prepared by the photochemical cyclisation of appropriately substituted stilbenes. Pyrolysis gives the corresponding benzo[ghi]fluoranthrenes in moderate yields. At higher temperatures a competing rearrangement pathway to cyclopenta[cd]pyrene occurs.
