Arenium ions polyfluorinated

Similar examples are also known in polyfluorinated arenium ions... [Pg.138]

For the ions with electronegative substituents at the ring sp hybridized carbon, the isomerization can proceed via the addition-elimination scheme. In this manner the polyfluorinated arenium ions are likely to be rearranged in acid media containing the donors of the fluoride-ion (HF, SbFr etc.) 238,239,413,414). [Pg.139]

The addition of a nucleophile is also predominant when quenching acid solutions of stable polyfluorinated arenium ions. Careful pouring into a frozen mixture of HCl with CH3OH effects the addition of Q When add solutions are... [Pg.193]

The addition and subsequent elimination of F from another carbon appear to account for the mentioned (see Sect. IV.l.B) isomerization of polyfluorinated arenium ions. [Pg.194]

However, other explanations of the reactions observed are not precluded. Thus, for polyfluorinated arenium ions a preliminary conversion of the ions into radical cations of the respective aromatic structures is discussed. Indeed, the radical cation of octafluoronaphthalene reacts with pentafluorobenzene to yield the same products as the perfluoro-a-naphthalenium ion does. [Pg.194]

A circumstantial review has been published dealing with the methods of generation and the properties of polyfluorinated arenium ions. [Pg.223]
