Stabilization of the alleged ‘bishomoromatic’ bicyclo[3.2.1]octa-2,6-dienyl anion by counterion interactions and by hyperconjugation
Abstract
Hyperconjugation and inductive effects, rather than homoaromaticity, are responsible for the stabilization of the title anion in the gas phase; interaction of the double bond with the Li+ gegenion in the endo geometry contributes additionally in solution.
