The Benzilic Acid Rearrangement is a chemical reaction that involves the conversion of benzil into benzilic acid. This rearrangement occurs when benzil, a diketone, is treated with a strong base, typically potassium hydroxide. The reaction involves the migration of a phenyl group and the formation of a carbanion intermediate, leading to the final product, benzilic acid. This reaction is significant in organic chemistry as it demonstrates the principles of rearrangement reactions and the stability of carbanions. The resulting benzilic acid can be further utilized in various synthetic applications, showcasing the versatility of this rearrangement in organic synthesis.
