Beckmann rearrangement
chemistry
Quick Summary
The Beckmann rearrangement is a chemical reaction where a ketoxime transforms into an amide derivative. This process typically involves treating the ketoxime with a reagent like phosphorus pentachloride or an acid. For example, the oxime of benzophenone can be converted into benzanilide through this rearrangement.1
This reaction is named after the German chemist Ernst O. Beckmann. The Beckmann rearrangement can be used in the synthesis of primary amines when followed by hydrolysis.12
