Abstract

The thermal (t-amyl alcohol, 200 to 250°) and acid catalyzed (2N H2SO4, 50 to 70°) rearrangement of N-(α,α-dimethylallyl)- anilines 1 to yield the corresponding 2-(γ,γ-dimethylallyl)-anilines 2 is described. The kinetic secondary H/D isotope effect for the thermal (kH/kD = 0,83, 237°) as well as for the acid catalyzed (kH/kD  = 0,84, 67,5°) rearrangement of N-(α,α-dimethylallyl)- aniline (1a) and its β,γ,γ-d3 derivative is in agreement with a [3,3]-sigmatropic process in the neutral and charged species, respectively.
