Question

Which of the following is not an example of Sand-meyer's reaction?

• A. $C_6{H}_5\stackrel{+}{N_2}{Cl}^{-}\underset{}{\overset{CuCl}{\to }}{C}_6{H}_{5}Cl$
• B. $C_6{H}_5\stackrel{+}{N_2}{Cl}^{-}\underset{}{\overset{CuBr}{\to }}{C}_6{H}_{5}Br$
• C. $C_6{H}_5\stackrel{+}{N_2}{Cl}^{-}\underset{}{\overset{CuCN}{\to }}{C}_6{H}_{5}CN$
• D. $C_6{H}_5\stackrel{+}{N_2}{Cl}^{-}\underset{KI}{\overset{}{\to }}{C}_6{H}_{5}I$

Answer 1

The correct option is D $C_6{H}_5\stackrel{+}{N_2}{Cl}^{-}\underset{KI}{\overset{}{\to }}{C}_6{H}_{5}I$

Sandmeyer reaction is a type of substitution reaction that is widely used in the production of aryl halides from aryl diazonium salts. Copper salts like chloride, bromide or iodide ions are used as catalysts in this reaction. Notably, the Sandmeyer reaction can be used to perform unique transformations on benzene.

Option (D) is not sandmeyer's reaction.
