Identify the product (A) in the following reaction.
(A)(see structure)
(B)(see structure)✓ Correct
(C)(see structure)
(D)(see structure)
Answer: (B)
Solution
The amine is diazotised with NaNO2/HCl at low temperature. A Sandmeyer reaction with Cu2Cl2 replaces −N2+ with −Cl. Forcing hydrolysis of this aryl chloride at high temperature and pressure (NaOH, 623 K, 300 atm, then acidification) then replaces −Cl with −OH, giving the substituted phenol as product A.
