The hydroarylation of 3-arylprop-2-yn-1-amine derivatives with arylboronicacids has been studied in the presence of rhodium or palladium catalysts. By using a rhodium-based catalytic system, β,γ-diarylallylamines were isolated in good yields. By contrast, the formation of the regiosomeric γ,γ-diarylallylamines was achieved by means of a palladium catalyst in the presence of acetic acid. The complementary
