Abstract

An one-pot method has been developed for the synthesis of azo dyes via sequential diazotizationâdiazo coupling of aromatic amines with coupling agents at room temperature in the presence of Bi(NO3)3. 5H2O. Short reaction times, high yields, a clean process, simple methodology, easy work-up and green âconditions are advantages of this protocol.â
