New Schiff bases of 1-vinyl-and 1-ethyl-substituted imidazoles and benzimidazoles were synthesized. The condensation reactions of 2-amino-and 2-formylimidazoles with 2-aminobenzimidazoles are virtually independent of the nature of the substituent (CH=CH₂ or Et) at position 1 of the heterocycle. The structures of the azomethines synthesized were established by ¹H NMR and IR spectroscopy.
