The conformati ons and the rotational barriers of the 2-substituted 1,3-diphenylallylanions lb-g (Tab.2) have been determined. Increasing size of the substituents leads tomore exo,endo-and endo,endo-conformers at the cost of the exo,exo-species. This trend is connected with decreasing AG\*-values of
