Notes:
The 1H NMR spectra of selected heptafulvenes 2a-e were analysed under high-resolution conditions. The results are in agreement with a symmetrical boat conformation for 2a and with a nearly planar conformation of 2e. Within the series 2a-e, ring planarization and π-delocalization increase. Substituent effects on NMR parameters are discussed.
