Beckmann Rearrangement

Beckmann rearrangement

[′bek·män rē·ə′rānj·mənt] (organic chemistry) An intramolecular change of a ketoxime into its isomeric amide when treated with phosphorus pentachloride.

Beckmann Rearrangement

a chemical reaction that converts oximes into acid amides under the influence of acidic dehydrating agents (PCl₅, H₂SO₄, oleum, and others):

where R and R’ are identical or different organic radicals (CH₃, C₂H₅, C₆H₅, and so on). The Beckmann rearrangement is used in industry to obtain kapron (a stage in the conversion of cyclohexanon oxime into ∊-caprolactam). The Beckmann rearrangement was discovered in 1886 by the German chemist E. O. Beckmann.
