PRIMARY ALIPHATIC AMINES

• HOW ARE PRIMARY AMINES PREPARED?

  reduction of nitriles, from halogenoalkanes
• STAGES 1?

  • halogenoalkanes react with CN-
  • in aqueous ethanol
  • CN- replaces X-
  • nucleophilic substitution
  • produces a nitrile
• STAGE 2?

  • nitriles reduced
  • to primary amines
  • using Ni/ H2 catalyst
• BENEFITS OF THIS METHOD OF PREPARATION?

  purer product as only primary amine formed
