The research focuses on the synthesis of aryl or benzyl-(Z)-N-[2-amino-1,2dicyanovinyl]formamidines, which are significant compounds acting as intermediates in various biological processes. The study describes a method to prepare these amidines by reacting ethyl(Z)-N-(2-amino-1,2dicyanovinyl)formimidate (1) with aromatic amines at room temperature in the presence of a catalytic amount of anilinium hydrochloride. The reactants include ethyl(Z)-N-(2-amino-1,2-dicyanovinyl)formimidate and various aryl or benzylamines. The analysis of the synthesized products involved techniques such as thin-layer chromatography (TLC), 1H and 13C NMR spectroscopy, mass spectrometry, and infrared spectroscopy, which confirmed the structure and purity of the compounds. The elemental analysis results were also satisfactory, and the mass spectra showed characteristic peaks for each product. The 1H NMR spectra revealed interesting features such as the coupling of benzylic protons to the NH proton, and the infrared spectra displayed strong absorption bands characteristic of CN stretching vibrations, along with NH and C?N stretching vibrations.
