Question

Write a short nots on Sandmeyer's reaction.

Answer 1

His reaction was the main part thing I ever seeen

Answer 2

This important reaction helps in transforming aromatic chemistry as there are some substitution patterns which can not be achieved through direct substitution.

The substitution of the aromatic amino group is done by preparing diazonium salt and displacement occurs with nucleophile (Cl-, I-, CN-, RS-, HO-).

Mainly, copper(I) catalysis is used.
