Sulfamic acid as an efficient and cost-effective catalyst for the synthesis of 2,4,5-triarylimidazoles and 2-arylphenanthrimidazoles

[摘要] A simple and efficient synthesis of 2,4,5-triarylimidazoles and 2-arylphenanthrimidazoles was developed using the one-pot, three-component condensation reaction of an aromatic aldehyde, benzil or 9,10-phenanthroquinone and ammonium acetate in refluxing ethanol in the presence of the catalyst sulfamic acid.
