Gallocyanine as An Efficient Catalyst for Synthesis of Benzimidazoles in Aqueous Ethanol

Gallocyanine as An Efficient Catalyst for Synthesis of Benzimidazoles in Aqueous Ethanol

The benzimidazole derivatives have been obtained catalyzed by gallocyanine. A wide range of aromatic aldehydes easily undergo condensation with substituted o-phenylendiamine under mild conditions to afford the target molecules in excellent yields. The products were obtained in 80–93% yields in 30–80...
