Pharmacologically active secondary and tertiary 1-(3,3- diarylpropyl)amines 1 are prepared in high yields and chemoselectivity by the reaction of 1,1-diarylethenes 4, primary or secondary amines 5, carbon monoxide and hydrogen in presence of [Rh(cod)Cl]₂/PBu₃ as catalyst via a one-pot hydroformylation - amine condensation - reduction sequence.
