A Simple and Effective Synthesis of Aryl Azides via Arenediazonium Tosylates
摘要:
Aromatic azides are formed in high yield from arenediazonium tosylates and sodium azide in water at room temperature or from aromatic amines via diazotization in the presence of p-TsOH. Besides being experimentally simple, these methods do not require any metal catalysis and provide clean products without purification.
