A study on the scope of the method to obtain N,N,N′-trisubstituted ethylenediamines III by monoalkylation of N,N′-disubstituted ethylenediamines I through a "one-pot" reaction is presented. It involves condensation of compounds I with aldehydes followed by reduction of the formed imidazolidines II without previous isolation.

1,2-Diaryl-substituted imidazolidines proved to be ring-chain tautomeric mixtures in CDCl3 at 300 K. Both 1- and 2-aryl groups exerted significant electronic effect on the tautomeric equilibria, which could be described by the equation log KX=ρ
