چکیده مقاله
Nanosilica periodic acid (nano-SPIA) is found to be a new, powerful, and reusable heterogeneous catalyst
for the rapid synthesis of 2-naphtholazo dyes via diazotization of aromatic amines and followsazo coupling
with 2-naphthol under solvent-free conditions at room temperature by grinding. Eco-friendly, heterogeneous
reaction conditions, high stability of diazonium salt, simple experimental procedures, and high yields are
some of the important advantages of this method.
