प्रश्न
Why cannot aniline be prepared by Gabriel phthalimide synthesis?
Advertisements
उत्तर
- Gabriel phthalimide synthesis is used for the preparation of aliphatic primary amines.
- It involves the nucleophilic substitution of alkyl halides by the anion formed by the phthalimide.
- But aryl halides do not undergo nucleophilic substitution with the anion formed by the phthalimide.
Hence, aniline cannot be prepared by Gabriel phthalimide synthesis.
