2-fluorobenzo[rst]pentaphene and 2-fluoro-benzo[rst]pentaphene-5- 13C (70% 13C) and their precursors are described, and relevant directly-bonded 13C-1H couplings reported.The labelled material was used to differentiate the NMR resonances of the 5- and 8-protons, in connection with our studies of the remote effect exercised by fluorine on their reactivities toward electrophilic aromatic substitution
