Diazo coupling reactions of aromatic amines with 2-naphthol in a green, efficient and easy procedure is described. Ferric hydrogensulfate catalyses this reaction in water at room temperature and short reaction time with high yields. The antibacterial activities of the synthesized compounds against four pathogenic bacteria are also investigated.

An efficient and green approach for the synthesis of azo dyes has been developed via the Brønsted acidic ionicliquid (IL) promoted diazo coupling reaction of naphthols with aryltriazenes. The reaction was carried out with the aryltriazenes as diazotizing agents, the Brønsted acidic ionicliquids as the promoter, and water as the green solvent at room temperature under air and metal-free conditions
