Explain sandmayer and diazotisation reaction with example |
| Answer» DIAZOTISATION. The NITROSATION of primary aromatic amines with nitrous acid (generated in situ from sodium nitrite and a strong acid, such as hydrochloric acid, sulfuric acid, or HBF4) leads to diazonium salts, which can be isolated if the COUNTERION is non-nucleophilic.The Sandmeyer reaction is an example of a radical-nucleophilic aromatic substitution (SRNAr). ... The substitution of the aromatic diazo group with a halogen or pseudohalogen is initiated by a one-electron transfer MECHANISM catalyzed by copper(I) to FORM an aryl radical with loss of nitrogen gas. | |
