Question

Match the reactions with their name:

• A. Schiemann reaction
• B. Swarts reaction
• C. Sandmeyer reaction

Answer 1

Synthesis of aryl chlorides/bromides from aryl diazonium salts using cuprous chloride/bromide is called Sandmeyer reaction.
Similarly halogen exchange reaction for the synthesis of alkyl fluorides from alkyl chlorides/bromides by treatment with silver fluoride is known as Swarts reaction.
Schiemann reaction is for the synthesis of aryl fluorides from aryl diazonium salts via a diazonium tetrafluoroborate intermediate.
