Which is the result of the Gabriel reaction?
Let’s put together a summary of the Gabriel reaction for preparing1° amines in which the overall result is nucleophilic substitution of X by NH2, so the Gabriel synthesis can be used:
Why is phthalimide used in the Gabriel synthesis?
This is called the Gabriel synthesis and it relies on phthalimide as the nucleophile. The idea here is to use a bulky nitrogen which can only perform one nucleophilic substitution: The N–H bond of the imide, being between two electron-withdrawing carbonyl groups, is quite acidic (p K a ~ 8.3).
Why is the Gabriel synthesis limited to primary amines?
The Gabriel synthesis is limited to the formation of primary amines because secondary and tertiary alkyl halides undergo competitive elimination reactions. Aryl halides cannot be used because they do not undergo nucleophilic substitution under these reaction conditions. Problem 23.13
What are the steps of the Gabriel synthesis?
Gabriel synthesis. The reaction begins with the deprotonation of the phthalimide which then attacks the alkyl halide in an S N 2 fashion to give an N-alkylphthalimide intermediate. The intermediate is then cleaved by hydrazine in a series of steps that end with the liberation of the final primary amine product and phthalhydrazide by-product. [1]
