The Gabriel phthalimide synthesis is a highly specialized reaction. Why is this method strictly unsu — Amines Chemistry Question

💡 Solution & Explanation

The critical second step of the Gabriel synthesis requires the phthalimide anion to nucleophilically attack an alkyl halide via an $S_N2$ mechanism. Aryl halides possess profound partial double bond character at the $C-X$ bond due to resonance, rendering them highly inert to standard nucleophilic substitution, effectively stopping the synthesis.
