Jan 23, 2023 · The Beckmann rearrangement is a reaction discovered in the mid-1880’s by the chemist Ernst Otto Beckmann. The reaction converts oximes into their corresponding amides 1 allowing the insertion of the nitrogen atom from the C=N bond into the carbon chain forming a C–N bond. Depending on the starting material, it could also produce nitriles ...

This chapter focuses on synthetically useful rearrangements including the pinacol, Payne, benzilic acid, Favorskii, Tiffeneau-Demjanov, Wolff, Curtius, Baeyer-Villager, and Beckmann rearrangements.
Jun 11, 2021 · The Beckmann rearrangement results when an oxime (an N-hydroxyimine) is treated with concentrated acid and heated. The oxime, in turn, is generated by treatment of a ketone with hydroxylamine. A catalytic amount of acid can activate the carbonyl, accelerating the otherwise sluggish reaction. The reaction, like the pinacol rearrangement, is ...

The Beckmann Rearrangement. The archetypal Beckmann rearrangement [4] is the conversion of cyclohexanone to caprolactam via the oxime. Caprolactam is the feedstock in the production of Nylon 6. [5] The Beckmann solution consists of acetic acid, hydrochloric acid and acetic anhydride, and was widely used to
