Various approaches for the synthesis of benzimidazole derivatives and their catalytic application for organic transformation

Imidazole and phenyl rings are fused at positions 4 5 to form the benzimidazole structure. The mono- disubstituted derivatives extremely intriguing heterocyclic chemical compounds. They can be synthesized using a straightforward condensation method between o-phenylenediamine carbonyl compound under various conditions as well nucleophilic substitution reaction. catalytical effects of derivatives, which include oxidation olefins, alcohol, etc, play significant role in catalysis. This review describes synthetic routes for synthesizing functionalized catalytic application Schiff base metal complexes amide.
