In the present study, a series of substituted 3-(1H-benzimidazol-2-ylsulfanyl)-1-phenylpropane-1, 2-dione was prepared. The synthesis of titled compounds from starting material unsubstituted 2-mercapto benzimidazoles was prepared from o-phenylenediamine and carbon disulfide in presence of KOH in single step.2-mercapto Benzimidazole on reacting with substituted 3-chloro-1-phenylpropane-1, 2-dione yield different derivatives of Benzimidazole. The structure of new compounds prepared during present investigation has been authentically established by their IR, 1H NMR and Mass spectral studies. The antibacterial and antifungal activities of benzimidazole derivatives were reported.

2-mercapto benzimidazoles, phenylpropane-1, 2-dione, antibacterial, antifungal.
