MNDO calculations were performed to estimate the aromaticity (antiaromaticity) of a series of fluorine-containing cyclopentadienyl, indenyl, and cyclopenta[b]naphthyl cations in terms of the Dewar-Breslow criterion which utilizes the difference in the enthalpies of formation of isomeric cations with closed and open pi-systems as aromaticity index. The aromaticity is strongly determined by both the structure of the carbon skeleton and the number and position of fluorine atoms. A linear correlation was revealed between the aromaticity index and the energy of the lowest singlet-singlet excitation for cations having a cyclic pi-system.
