Beschreibung

Anwendung

Phthalimide potassium salt (PPI) is widely used for the synthesis of primary amines from corresponding alkyl halides, known as Gabriel synthesis. Some of the other applications are:

• Preparation of phthalimidogold precatalyst for gold catalysis.
• It can be used in the palladium-catalyzed enantioselective synthesis of α- and β-amino acids.
• Potassium phthalimide is as an effective organocatalyst for the cyanosilylation of carbonyl compounds to synthesize cyanohydrin trimethylsilyl ethers.
