The Beckmann rearrangement is a fundamental reaction in organic chemistry that allows the conversion of oximes into amides, often used in the synthesis of lactams. This process is influenced by factors such as acidity, temperature, and solvent choice, and can be catalyzed by various acids. It has significant industrial applications, including the production of Nylon 6 from ε-caprolactam and adipic acid for nylon. Understanding migratory aptitude is crucial for predicting the reaction's outcome.
