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, 1 H, 13 C NMR and mass spectra.
