Which type of amines are prepared by Gabriel phthalimide reaction?

Explanation

**Step-by-Step Solution:**

1. **Understanding Gabriel Phthalimide Reaction**: The Gabriel phthalimide reaction is a well-known method for synthesizing primary amines. It involves the use of phthalimide as a starting material.

2. **Formation of Phthalimide Anion**: In the reaction, phthalimide is treated with a strong base (like NaOH or KOH). This base deprotonates the nitrogen in phthalimide, forming a phthalimide anion.

3. **Alkylation Step**: The phthalimide anion then acts as a nucleophile and reacts with an alkyl halide (R-X), where R is an alkyl group and X is a halogen. This step results in the formation of N-alkyl phthalimide.
