1-Fluoropentahelicene and substituted derivatives have been synthesized by the photocyclodehydrogenation of 1,2-di(2-naphtyl) ethylenes (1) and 3-styrylphenanthrenes (2).In two cases (1a and 2d) the photocyclisations gave rise to benzo perylenes (7, 8, 23, 24) a reaction involving either the loss (8, 24) or the fluorine atom.The 1H-NMR spectra are described.
