We have found that the specific rate of β£-sulfonyl carbanion formation in a β€-substituted sulfone shows a sizable dependence on the H C β£ C β€ X torsion angle. Defining k N = (k exch ) X /(k exch ) model (where the model has X = H or an alkyl group) we observed for a collection of β€-alkoxy sulfones (
