Notes:
The radical anions and the radical cations of 1-3 in which three π systems are connected in three dimensions by a strained propellane spacer were studied by ESR/ENDOR/TRIPLE spectroscopy. The hyperfine data of acenaphthene (4) are compared with those of the fused π systems 5-10. In the relatively persistent radical anions of 1-3, the spin is mainly confined to the two naphthalene moieties. Whereas the radical cation of 2 resembles a naphthalene trimer, the radical cations of intact 1 and 3 cannot be detected. The ESR spectra recorded upon one-electron oxidation of 1 and 3 are assigned to the radical cations of 9 and 10, respectively, formed by the loss of one naphthalene moiety from the parent molecules.
