78SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL PROPERTIES OF METAL 1-(4-CARBOXY 3-HYDROXY PHENYL AMINOMETHYL) BENZIMIDAZOLE COMPLEXESAminomethylation (i.e. Mannich reaction) of benzimidazole was carried out by treating benzimidalzole with formaldehyde and 4-aminosalicylic acid. The transition metal complexes of Cu2+, Co2+, Ni2+ and Mn2+ of BenzimidazoleSalicylate have been prepared and characterized by elemental analyses, spectral studies and microbicidal activity.avvasiva@gmail.comReview5120153(H) Benzimidazole, 4-Aminosalicylic acid,Metal complexes,Spectral studies,Antibacterial,antifungal activityK Trinagaraju,A.
