correlating the structure (bowl depth) and the energy of bowl inversion. Substituents placed in the peri positions are repulsive and flatten the bowl, thus causing a decrease in the bowl inversionbarrier. Conversely, annelation across the peri positions causes a deepening of the bowl, thus an increase in the bowl inversionbarrier. Barriers between 8.7 and 17.3 kcal/mol have been measured, and their
