Question

write a note on sandmeyer's reaction

Answer 1

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts.[1][2][3] It is an example of a radical-nucleophilic aromatic substitution. The Sandmeyer reaction provides a method through which one can perform unique transformations on benzene, such as halogenation, cyanation, trifluoromethylation, and hydroxylation.

Answer 2

Sandmeyer reaction :

On mixing freshly prepared solution of benzene diazonium chloride with cuprous halides (chlorides and bromides), aryl halides are obtained.
