Sažetak
We investigate the gas-phase reaction of Nb+ and Fe+ ions with perfluoronaphthalene and perfluoroanthracene compounds. The perfluoro effect shifts the σ -orbitals of these compounds to higher ionization energies and, as a result, they exhibit several outer-valence-ring π -orbitals. It might be expected that reactions with these compounds will proceed mostly through π -interaction between the metal and PAH orbitals. Surprisingly, as we will see, this is not the case. Fe+ reacts with perfluoronaphthalene (NF8) and perfluoroanthracene (AF10) by successive addition and (sandwich) dimer formation. Nb+, however, reacts by extraction of F atoms, preferably 4, followed by the formation of dimers that do not contain any metal atoms. The structure of this abundant ionic product AF6 is elucidated by quantum chemical calculations.
