Bi(NO3)3.5H2O: An efficient acidic reagent for synthesis of azo dyes at room temperature
Authors
Abstract:
An one-pot method has been developed for the synthesis of azo dyes via sequential diazotization–diazo 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 conditions are advantages of this protocol.

A convenient, rapid, and one-pot method for the synthesis of azo dyes has been developed. In this protocol, diazotization reagent (ArN2+ -CrO3–SiO2) was prepared via grinding of aromatic amines, NaNO2, wet SiO2 and nano silica chromic acid (Nano-SCA) without solvent at room temperature. The obtained diazotization reagent was suff...
