Pd‐Catalyzed Reductive Carbonylation‐Ring Closure of Aryl Halides: A Direct Approach for Synthesis of Benzimidazoles

A novel protocol is reported for the facile one‐pot benzimidazole derivatives formation from Pd‐catalyzed reaction of aryl halides (X=I, Br, ‐Cl), Fe(CO)5, and o‐diaminobenzene or o‐nitroaniline. Aryl halides are first converted to aryl aldehydes using Fe(CO)5 which then undergo ring closure with o‐...
