The Cope Rearrangement is a chemical reaction involving the rearrangement of certain organic compounds known as 1,5-hexadienes. This process typically occurs through a thermal reaction, where the molecule undergoes a shift in the position of its double bonds, resulting in a new structural isomer. This rearrangement is significant in organic chemistry because it allows for the formation of different compounds from the same starting material. The Cope Rearrangement is often used in synthetic chemistry to create complex molecules and is a valuable tool for chemists in designing new substances.
