Abstract

Ethoxymethylene derivatives of 2,4-pentanedione (Ia), 3-oxobutanenitrile (Ib), methyl (Ic) or ethyl (Id) 3-oxobutanoate give with 4- or 5-aminobenzimidazole or benzotriazole, respectively, under mild conditions products of nucleophilic substitution II-V. Structure of these compounds was discussed on the basis of their spectral measurements - IR, UV, 1H, 13C NMR and mass spectra.
