The Beckmann Rearrangement is a chemical reaction that transforms an oxime into an amide. This process typically involves the reaction of an oxime with an acid catalyst, leading to the migration of a carbon chain and the formation of a new carbon-nitrogen bond. This rearrangement is significant in organic chemistry for synthesizing various amides, which are important in pharmaceuticals and materials science. The reaction is named after the German chemist August Beckmann, who discovered it in the late 19th century, contributing to the understanding of organic transformations.
