preferred direction of positive charge control within 1+ s 5+ is of course consistent with the cyclopropylcarbinyl cationic nature of 5+. But do our experimental findings denote that the nortriquinacenyl anion is stabilized by homoaromatic delocalization or other homoconjugated interaction? Or is 1-favored simply because of greater electronic destabilization within 5-. And to what extent does ring strain affect partitioning to products?
