Diazotization and diazo coupling reactions using the Triethyl ammonium acetate as a ionic liquid

Aromatic diazonium salts have drawn increased attention as important intermediates in many organic reactions, especially for carbon-carbon bond formation via cross-coupling reactions[1,2]. Azo dyes are very important synthetic dyes which are used extensively in industry, So the topics of diazonium salts are interested to researchers. Since the coupling reactions are often carried out in strong acid conditions which are adverse to protection the environment. [3] Herein, we wish to report the diazo coupling reactions in ionic liquids wich don‘t have the disadvantages of using strong acid,[4] recently using of ionic liquids as solvents has been developed. Triethyl ammonium acetate is known as an ionic liquid wich has biological applications, so has been chosen as the reaction substrate to elimination the disadvantages of the old methods.[5,6]
