Homoaromaticity in anions: the effect of electron donor groups
Abstract
Base-catalysed exchange of 2,4-di-p-anisoylbicyclo[3.2.1]octa-2,6-diene (10) proceeds faster than that of 2,4-di-p-anisoylbicyclo[3.2.1]oct-2-ene (13) indicating the significance of homoaromaticity in anions and the utility of the electron-demand tool to detect such interactions.
