The Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines. Traditionally, the reaction uses potassium phthalimide. The alkylation of ammonia is often name reactions and reagents in organic synthesis pdf unselective and inefficient route to amines.
In this method, the sodium or potassium salt of phthalimide is N-alkylated with a primary alkyl halide to give the corresponding N-alkylphthalimide. Separation of phthalhydrazide can be challenging. For these reasons, other methods for liberating the amine from the phthalimide have been developed. Many alternative reagents have been developed to complement the use of phthalimides.
