Abstract

Aromatic azides are formed in high yield from arenediazonium tosylates and sodium azide in water at room temperature. An in situ diazotization followed by azidation in the presence of p-TsOH allows the direct transformation of aromatic amines. Besides being experimentally simple, these methods do not require any metal catalysis and provide clean products without purification.
