Notes:
Nature and extent of nonconjugated π,π interactions in (bis)-secododecahedradienes and (pentagonal, non-pentagonal) dodecahedradienes with transannular π,π distances ranging from ca. 2.8 to ca. 3.5 Å - representing well defined points on the D2h [π2 + π2] reaction coordinate - were studied by PE spectroscopy. The π,π splitting of 0.68 eV measured at the largest π,π distance of ca. 3.5 Å (1,16-dodecahedradiene 3a) was attributed to ca. 50% each of through-space and through-bond conjugation (analysis of precanonical MOs).
