Abstract
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.
