Synthesis and characterization benzimidazole ring by using O-phenylinediamine with different compounds and using mannich reaction for preparation of some derivatives

Abstract

The research includes synthesis and characterization Benzimidazole rings by using different compounds such as Urea, Thiourea and Carboxylic acid by reactant with O-phenylinediamine, then substitution hydrogen atom with present on nitrogen atom by reactant with primary and secondary amines according to Mannich reaction. Compounds was organized by using F.T.I.R and HNMR spectroscopy.
