A series of Schiff bases (3.a–f) bearing benzimidazole moiety was successfully synthesized in ethanol by refuxing Oct2-ynoic acid (1,3-dihydrobenzimidazole-2-ylidene)amide with substituted amines. Fourier transform infrared (FTIR), ultra violet light (UV–VIS), elemental analysis, proton (1 H) and carbon (13C) nuclear magnetic resonance spectroscopy were used to characterize the newly synthesized Schiff bases. | Benzimidazole Schiff base derivatives Synthesis characterization and antimicrobial activity
