The acidity of fluorinated bicycloalkanes. 1. 1-Undecafluoro- and 1,4-decafluorobicycloheptanes

CNDO/2 Calculations have been performed on the title compounds and on the anions derived from them. The results indicate that in the anion there is significant transannular transfer of charge to the 4-position. The amount of such transfer is effectively independent of the 4-substituent. It is concluded that the effect of the substituent upon the stability of the acid must be an important factor.
