Abstract
The 1H NMR chemical shifts of the cyclic conjugated hydrocarbon carbanions: cyclopentadienyl, cyclooctatetraene, cyclononatetraenyl, benzyl and methylene-cyclooctatrienyl anions, have been studied by a semiempirical approach in which the alkali counter ions are explicitly taken into account. The importance of electrostatic and covalent interactions between the ions and the ion-pairing effects on the proton shifts are elucidated.
