Notizen: Abstract In this work we present mechanism of the base-catalyzed 2-azaallylic rearrangement in homogeneous media. Detailed 2-azaallylic rearrangement studies have shown that tautomerism of derivatives of benzylidenebenzhydrylamines and N-fluorenylidenebenzylamines is not adequately encomposed by the Hammet equation and the equilibrium constant in the case of studied derivatives depends on the electronic as well as steric factors of the azaallylic system substituents. The presence of steric interactions which influence the equilibrium state has been additionally confirmed by means of crystallographic and molecular mechanics data as well as NOE studies.
