The mass spectrum of tropylium fluoroborate (C 7 H 7 + BF 4 − ) shows a base peak corresponding to the cationic portion of the salt ( m/e 91) and intense peaks occur at m/e 109 (C 7 H 6 F + ) and m/e 110 (C 7 H 7 F +. ). The latter peaks are probably of thermal origin. A similar rearrangement is observed in trityl fluoroborate (C 19 H 15 + BF 4 − ) and may be a general feature of the mass spectra of aromatic fluoroborates.
