Gabriel's synthesis

WebThe Gabriel amine synthesis is a method for preparing a primary amine from an alkyl halide. The reaction involves the alkylation of phthalimide. In phthalimide, the N-H hydrogen is acidic due to the two flanking carbonyl groups. Thus, phthalimide can be deprotonated by a strong base. The resulting anion is a strong nucleophile and readily ...

The reaction is named after the German chemist Siegmund Gabriel. The Gabriel reaction has been generalized to include the alkylation of sulfonamides and imides, followed by deprotection, to obtain amines (see Alternative Gabriel reagents).
