摘要

Oxidative photocyclization of l-fluoro [5] helicene and two of its chlorine-substituted derivatives leads to the formation of 8-fluorobenzo [ghi] perylenes through an unprecedented inter-ring fluorine atom migration; photoelimination of HF to give benzo [ghi] perylenes also occurs as a competing process. The rearrangement pathway predominates when the irradiation is carried out at 0" C in air-saturated benzene solution containing M ...
